Beta sheet
Videos
The beta sheet is a common motif of the regular protein secondary structure. Beta sheets consist of beta strands connected laterally by at least two or three backbone hydrogen bonds, forming a general

Protein folding

Protein folding is the physical process by which a protein, after synthesis by a ribosome as a linear chain of amino acids, changes from an unstable random coil into a more ordered three-dimensional s

…connected by hairpins, while the fourth is adjacent to the first and linked to the third by a longer loop. This type of structure forms easily during the protein folding process. It was named after a pattern common to Greek ornamental artwork (see meander). Due to the chirality of their component amino acids, all strands…
