Yolk

Among animals which produce eggs, the yolk is the nutrient-bearing portion of the egg whose primary function is to supply food for the development of the embryo. Some types of egg contain no yolk, for example because they are laid in situations where the food supply is sufficient or because the embryo develops in the parent's body, which supplies the food through a placenta. Reproductive systems in which the mother's body supplies the embryo directly are said to be matrotrophic. In many species, such as all birds, most reptiles and insects, the yolk takes the form of a special storage organ constructed in the reproductive tract of the mother. In many other animals very small species such as some fishes and invertebrates, the yolk material is not in a special organ, but inside the egg cell; as stored food, yolks are rich in vitamins, minerals and proteins. The proteins function as food in their own right, in regulating the storage and supply of the other nutrients. For example, in some species the amount of yolk in an egg cell affects the developmental processes that follow fertilization.

The yolk is not living cell material like protoplasm, but passive material, to say deutoplasm. The food material and associated control structures are supplied during oogenesis; some of the material is stored more or less in the form in which the maternal body supplied it as processed by dedicated non-germ tissues in the egg, while part of the biosynthetic processing into its final form happens in the oocyte itself. Apart from animals, other organisms, like algae, specially in the oogamous, can accumulate resources in their female gametes. In gymnosperms, the remains of the female gametophyte serve as food supply, in flowering plants, the endosperm. In avian eggs, the yolk is a hue of yellow in color, it is spherical and is suspended in the egg white by one or two spiral bands of tissue called the chalazae. The yolk mass, together with the ovum proper are enclosed by the vitelline membrane, whose structure is different from a cell membrane; the yolk is extracellular to the oolemma, being not accumulated inside the cytoplasm of the egg cell, contrary to the claim that the avian ovum and its yolk are a single giant cell.

After the fertilization, the cleavage of the embryo leads to the formation of the germinal disc. As food, the chicken egg yolk is a major source of minerals, it contains all of the egg's fat and cholesterol, nearly half of the protein. If left intact when an egg is fried, the yellow yolk surrounded by a flat blob of egg white creates a distinctive "sunny-side up" form. Mixing the two components together before cooking results in a pale yellow mass, as in omelets and scrambled eggs; the developing embryo inside the egg uses the yolk as sustenance. It is at times separated from the egg white for cooking, is employed as an emulsifier, is used in mayonnaise, hollandaise sauce, crème brûlée, avgolemono and ovos moles, it is used in painting as a component of traditional egg-tempera. It is used in the production of egg yolk agar plate medium, useful in testing for the presence of Clostridium perfringens. Egg yolk contains; the antibody transfers from the laying hen to the egg yolk by passive immunity to protect both embryo and hatchling from microorganism invasion.

Egg yolk can be used to make liqueurs such as eggnog. Egg yolk is used to extract egg oil which has various cosmetic and medicinal uses; the yolk makes up about 33% of the liquid weight of the egg. The yolk of one large egg (56.7 g total, 17.6 g yolk. All of the fat-soluble vitamins are found in the egg yolk. Egg yolk is one of the few foods containing vitamin D; the composition of the most prevalent fatty acids in egg yolk is: Unsaturated fatty acids: Oleic acid, 47% Linoleic acid, 16% Palmitoleic acid, 5% Linolenic acid, 2% Saturated fatty acids: Palmitic acid, 23% Stearic acid, 4% Myristic acid, 1%Egg yolk is a source of lecithin, as well as egg oil, for cosmetic and pharmaceutical applications. Based on weight, egg yolk contains about 9% lecithin; the yellow color is due to lutein and zeaxanthin, which are yellow or orange carotenoids known as xanthophylls. The different yolk's proteins have distinct roles. Phosvitins are important in sequestering calcium and other cations for the developing embryo.

Phosvitins are one of the most phosphorylated proteins in nature. Lipovitellins are involved in lipid and metal storage, contain a heterogeneous mixture of about 16% noncovalently bound lipid, most being phospholipid. Lipovitellin-1 contains two chains, LV1N and LV1C. Yolks hold more than 90% of the calcium, phosphorus, thiamine, vitamin B6, vitamin B12, pantothenic acid of the egg. In addition, yolks cover all of the fat-soluble vitamins: A, D, E, K in the egg, as well as all of the essential fatty acids. A single yolk from a large egg contains 22 mg of calcium, 66 mg of phosphorus, 9.5 micrograms of selenium, 19 mg of potassium, according to the USDA. Double-yolk eggs occur when ovulation occurs too or when one yolk becomes joined with another yolk; these eggs may be the result of a young hen's r

Tobacco Factory Theatre

Tobacco Factory Theatres is located on the first floor of the Tobacco Factory building on the corner of North Street and Raleigh Road, Southville in Bristol, England. The theatre itself is a studio-style space, with a low ceiling and fixed grid with structural pillars which intrude into the acting area. There is a dance studio and Box Office; the theatre can seat up to 350 people, although it has a capacity of about 250. The programme includes classic and contemporary theatre, dance, film, opera and family shows. In 2012 over 100,000 people came through the theatre doors and the theatre is attracting national critical acclaim. Tobacco was the main industry in South Bristol from the beginning of the twentieth century and at its peak around 40% of the local workforce worked in the Imperial Tobacco Factory; the relocation of Imperial Tobacco in the 1980s was devastating to the local area, causing massive unemployment and deprivation. The Tobacco Factory building itself fell into disrepair but was renewed from the late 1990s when George Ferguson acquired the building, inviting Show of Strength Theatre Company to use part of the first floor as a theatre space.

The building became a mixed-use cultural space with a café-bar and a 250-seat studio theatre, under the name of Tobacco Factory Theatre. In 2005 the Tobacco Factory Theatres became a charitable trust and in 2007 it became a Key Arts Provider of Bristol City Council, it has expanded since 2008. It now has two rehearsal spaces, it has made capital improvements, including the installation of a renewable energy system. The theatre attracts national critical acclaim, it has strong relationships with venues and with theatre companies. It is well known for productions by Shakespeare at the Tobacco Factory, inhouse family-friendly productions and a comedy line-up, as well as classic and contemporary theatre, puppetry, film and music; the theatre was redesigned in 2013 and has become one of the UK's few Theatre-in-the-Round auditoria, increasing the maximum seating capacity to 350, with improved comfort and sightlines. The theatre can still be used for thrust stage performance; the Brewery Theatre opened its doors for the first time on 29 August 2009.

An old tyre garage, the building is 160 yards down the road from the Tobacco Factory and houses the 90-seat Brewery Theatre and Brewery dance studio with sprung floor. The building is home to Mark’s Bread bakery and cafe, a Bristol Beer Factory Brewery and Visitors' centre; the Brewery Theatre is programmed with theatre from small scale touring companies to Tobacco Factory Theatre productions. The shows programmed are a range from children’s shows and magic, to clowning, comedy and classical theatre; the Last Voyage of Sinbad the Sailor Hansel and Gretel The Lost Present The Room in the Elephant Faith Fall Made in Heaven Cinderella: A Fairytale The Adventures of Pinocchio Ali Baba and The Forty Thieves A Christmas Carol The Ugly Duckling Alice Through The Looking Glass Topless Mum Tobacco Factory Theatres receives seven percent of its funding from public sources such as the Arts Council of England. They raise 85% of their income through box office receipts, bar sales and space hire, they offer various levels of membership on which they rely to allow the theatre to produce high-quality work.

The theatre is recognised by Bristol City Council as a key arts provider. The theatre received funding from the Arts Council of England for the first time in 2007. List of theatres in Bristol
