WebThe beta sheet, (β-sheet) (also β-pleated sheet) is a common motif of the regular protein secondary structure.Beta sheets consist of beta strands (β-strands) connected laterally by at least two or three backbone hydrogen bonds, forming a generally twisted, pleated sheet.A β-strand is a stretch of polypeptide chain typically 3 to 10 amino acids long with … WebNot only do the hydrogen bonds hold the chains together, they also are very specific in which bases are connected by the hydrogen bonds. Adenine (A) forms two hydrogen bonds only with thymine (T). Guanidine (G) forms three hydrogen bonds only with cytosine (C). In each case, the hydrogen bond is formed between the positive hydrogen end of …

Therefore, the G-C pairing is more stable than the A-T pairing. Thus, strands with more G-C content have more hydrogen …
Web17 aug. 2024 · The secondary structure of proteins. Within the long protein chains there are regions in which the chains are organised into regular structures known as alpha-helices (alpha-helixes) and beta-pleated sheets. These are the secondary structures in proteins. These secondary structures are held together by hydrogen bonds.
