Pentose

In chemistry, a pentose is a monosaccharide with five carbon atoms. The chemical formula of all pentoses is C5H10O5, their molecular weight is 150.13 g/mol. Pentoses are important in biochemistry. Ribose is a constituent of RNA, the related molecule, deoxyribose, is a constituent of DNA. Phosphorylated pentoses are important products of the pentose phosphate pathway, most ribose 5-phosphate, used in the synthesis of nucleotides and nucleic acids, erythrose 4-phosphate, used in the synthesis of aromatic amino acids. Like some other monosaccharides, pentoses exist in two forms, open-chain or closed-chain, that convert into each other in water solutions; the linear form of a pentose, which exists only in solutions, has an open-chain backbone of five carbons. Four of these carbons have one hydroxyl functional group each, connected by a single bond, one has an oxygen atom connected by a double bond, forming a carbonyl group; the remaining bonds of the carbon atoms are satisfied by six hydrogen atoms.

Thus the structure of the linear form is H–x–C–4-x–H, where x is 0, 1, or 2. The term "pentose" sometimes is assumed to include deoxypentoses, such as deoxyribose: compounds with general formula C5H10O5-y that can be described as derived from pentoses by replacement of one or more hydroxyl groups with hydrogen atoms; the aldopentoses are a subclass of the pentoses which, in the linear form, have the carbonyl at carbon 1, forming an aldehyde derivative with structure H–C–4–H. The most important example is ribose; the ketopentoses have instead the carbonyl at positions 2 or 3, forming a ketone derivative with structure H–CHOH–C–3–H or H–2–C–2–H. The latter are not known to occur in nature, are difficult to synthesize. In the open form, there are 8 aldopentoses and 4 2-ketopentoses, stereoisomers that differ in the spatial position of the hydroxyl groups; these forms occur in pairs of optical isomers labelled "D" or "L" by conventional rules. The aldopentoses have three chiral centers. Ribose is a constituent of RNA, the related molecule, deoxyribose, is a constituent of DNA.

Phosphorylated pentoses are important products of the pentose phosphate pathway, most ribose 5-phosphate, used in the synthesis of nucleotides and nucleic acids, erythrose 4-phosphate, used in the synthesis of aromatic amino acids. The 2-ketopentoses have two chiral centers; the 3-ketopentoses are rare. The closed or cyclic form of a pentose is created when the carbonyl group interacts with an hydroxyl in another carbon, turning the carbonyl into a hydroxyl and creating an ether bridge –O– between the two carbons; this intramolecular reaction yields a cyclic molecule, with a ring consisting of one oxygen atom and four carbon atoms. The closure turns the carboxyl carbon into a chiral center, which may have any of two configurations, depending on the position of the new hydroxyl. Therefore, each linear form can produce two distinct closed forms, identified by prefixes "α" and "β"; the one deoxypentose has two steroisomers, for two total steroisomers. In the cell, pentoses have a higher metabolic stability than hexoses.

A polymer composed of pentose sugars is called a pentosan. The most important tests for pentoses rely on converting the pentose to furfural, which reacts with a chromophore. In Tollens’ test for pentoses the furfural ring reacts with phloroglucinol to produce a colored compound. In each of these tests, pentoses react much more and than hexoses

La Salle College Antipolo

La Salle College Antipolo, or La Salle Antipolo, is a Lasallian educational institution located in Antipolo City, Rizal, in the Philippines. It was founded as a La Salle School by Br Rolando Dizon FSC, a past President of De La Salle University, Manila, in 1986; the construction of the school began on March 16, 1985. During this time, Kindergarten to Fourth Grade classes were temporarily held first at La Salle Green Hills. Construction was delayed because of the costs and logistics that were involved in building a school on a mountain. Classes were transferred to the Antipolo campus on January 13, 1986 and were housed in two buildings. A third building was completed in the summer of 1987, with a fourth one completed in 1989; the school's St. Benilde Multi-purpose Hall was finished in 1991, while the high school and laboratory-library buildings were completed in 1994; the Tertiary Education Unit was launched in 1998, with BS in Elementary Education and BS in Accountancy as the pioneer offerings.

Skippy Roberge

Joseph Albert Armand "Skippy" Roberge was an American professional baseball player, an infielder whose professional career lasted for ten seasons between 1939–1952 and included 177 games played in Major League Baseball for the Boston Braves. Skippy Roberge was born in Lowell, Massachusetts, on May 19, 1917, he attended Keith Academy, now part of Lowell Catholic High School, from 1933–1937, where he was the football quarterback, All-American forward for the basketball team, shortstop and pitcher for the baseball team. He did not attend college. After high school, Roberge joined a semi-pro baseball team in the Lowell Twilight League, the Lowell YMCA basketball team, where he played until 1938 when he tried out for the Braves nicknamed the Boston Bees. Manager Casey Stengel liked what he saw and assigned Roberge to a Class D farm team, the Bradford Bees, for 1939; the next year, in 1940, Roberge moved up to the Class B team, the Evansville Bees to the Class A team, the Hartford Bees, before entering the Majors.

Roberge was a right-handed backup utility Infielder for the Boston Braves from 1941–1942, 1946. Listed at 5 feet 11 inches 185 pounds, he made his Major League debut at the age of 24, he never started a game, but finished his career with 508 at-bats and a.220 batting average, with 3 home runs. 1941: 15 RBIs.216 batting average. 1942: 12 RBIs.215 batting average. 1943–1945: Roberge served in the United States Army during World War II. 1946: 20 RBIs.231 batting average. All in all, Roberge batted in 177 games with a career slugging percentage of.283. He fielded in 163 games with 17 errors, a.972 fielding percentage. Roberge served with the U. S. Army Company C, 52d Infantry Regiment, 4th Signal Battalion with the rank of Technician Fifth Grade; the first few months while stationed in England, he played and taught baseball as part of a traveling squad around England. But in late 1944, as the Allied Forces advanced, Roberge was sent to the front lines, where he was wounded in the Roer River crossing at Linnich, Germany, on February 14, 1945, which earned him the Purple Heart.

Roberge was discharged in December 1945. Though his war wound hindered his return to the majors, Roberge continued to play baseball in the minor leagues, he retired from the game for the 1951 season, but spent one final season in the minors playing for the Double-A Little Rock Travelers in 1952 before leaving professional baseball at the age of 35. He worked the next 22 years back in his hometown at the General Electric Company, while coaching local youth leagues. Roberge was inducted into the Lowell Catholic High School's Athletic Hall of Fame. Roberge died in his hometown of Lowell on June 7, 1993, at the age of 76, is buried in St. Joseph Cemetery in Lowell. Baseballinwartime.com, Family Article

Hyozo Omori

Hyozo Omori was a Japanese physical education specialist who studied in America and married the American artist Annie Barrows Shepley. In Japan, they established Yurin En, a settlement house and leader in the Japanese playground movement. Omori introduced basketball and volleyball to the country and was the team manager at the 1912 Stockholm Olympics in Sweden. Hyozo Omori was in the 1905 class of Stanford University and continued his studies in Springfield, Massachusetts as a YMCA exchange student, he graduated from YMCA's College in Springfield with honors in 1907. In October 1907, Omori married artist Annie Barrows Shepley. In 1908, when he had returned to Japan, he introduced volleyball and basketball to the country and became known as the "Father of Japanese Basketball". In Tokyo, the Omoris established a settlement house, Yurin En which offered dramatic classes and a playground for children, it offered courses in sewing, flower arranging and crafts as well as mother's meetings and opportunities for people to speak English.

They met resistance because of their co-educational programs, the fact that the Omoris were Christian, that they broke down well-establish class barriers. The Yurin En was at the forefront of the Japanese playground movement. In 1909, Omori was the Physical Director for the Japanese Association; that year, he wrote "A Brief Survey of the Present Conditions of Physical Education in Japan" for Hygiene and Physical Education. Hyozo Omori was a physical education specialist and team manager for the Japanese team that competed in the 1912 Stockholm Olympics in Sweden. Yahiko Mishima from Tokyo Imperial University ran short distances and Shizo Kanakuri, a 20-year-old Tokyo Higher Normal School student ran the marathon. Judo master Kanō Jigorō was the leader of the team, it was the first time. Omori became quite ill when the group arrived in Stockholm following the Trans-Siberian Railway trip. Hyozo Omori died in 1913, Annie continued running Yurin En after his death

Moroccan British Society

The Moroccan-British Society was created on 23 February 2003. Its goal is ‘to provide means and allow Moroccans and British people to acquire a better mutual understanding of their civilizations and political, scientific, economic and commercial institutions so as to promote and foster their friendly relations and their cooperative ties in every domain.’ Lalla Joumala is president of the MBS since its inception. Lalla Joumala called for greater dialogue between faiths. Speaking at a 2007 conference on the necessity for Muslims to adopt democracy, she said that there was a ‘vital necessity’ to increase dialogue between the three religions. Joumala described the project as ‘aiming to foster inter-religious dialogue in these times of prevalent political and religious tensions internationally’, she went on: ‘The Moroccan British Society, in contributing to this event, seeks to underline the Moroccan example, where interfaith respect is the norm. Islam in Morocco has always opposed extremism and enabled people to live in peace and good intelligence with all faiths and religious communities.

In 2004, the Middle East Centre at St Antony’s College of Oxford University received a £1.5m donation from the Moroccan British Society to establish ‘the King Mohammed VI Fellowship in Moroccan and Mediterranean Studies’. In 2007, Eugene Rogan wrote that ‘The King Mohammed VI Fellowship in Moroccan and Mediterranean Studies has served as the basis for extending cooperation between Moroccan academics and Great Britain, has enabled the MEC to develop its work in North Africa significantly.’ This was criticised by Robin Simcox of the Centre for Social Cohesion.
