bétaszsheet
Bétaszsheet is a term sometimes used colloquially to refer to a beta-pleated sheet secondary structure found in proteins. Beta-pleated sheets are a common structural motif in proteins, alongside alpha-helices. They are formed by hydrogen bonds between backbone atoms of adjacent polypeptide chains or different segments of the same chain. These hydrogen bonds occur between the carbonyl oxygen of one amino acid residue and the amide hydrogen of another.
There are two main types of beta-pleated sheets: parallel and antiparallel. In an antiparallel beta-pleated sheet,
Beta-pleated sheets contribute to the overall three-dimensional structure and stability of proteins. They can form rigid,
