Discuss the secondary structure of peptides

WebMay 4, 2024 · Secondary Structure refers to the coiling or folding of a polypeptide chain that gives the protein its 3-D shape. There are two types of secondary structures observed in proteins. One type is the alpha (α) helix structure. This structure resembles a coiled spring and is secured by hydrogen bonding in the polypeptide chain. WebThe secondary structure is formed by hydrogen bonds between carbonyl and amino groups that make up the polypeptide backbone and causes the molecule to either bend and fold (beta pleated sheet) or spiral around (helicase).

Instead, the chains are arranged in unique but specific conformations. The term secondary structure refers to the fixed arrangement of the polypeptide backbone.

WebAug 23, 2024 · When two amino acids link together to form an amide link, the resulting structure is called a dipeptide. Likewise, we can have tripeptides, tetrapeptides, and other polypeptides. At some point, when the structure is long enough, it is called a protein. The average molecular weight of proteins in yeast is about 50,000 with about 450 amino acids. WebSecondary Protein Structure α -Helices, β -sheets, and triple helices are three types of secondary structures. All are formed and stabilized by noncovalent interactions, mainly hydrogen bonds.
