A polypeptide chain is a sequence of amino acids linked together by peptide bonds, forming the primary structure of proteins. It folds into specific shapes to become functional proteins.
5 Must Know Facts For Your Next Test
Polypeptide chains are synthesized by ribosomes during the process of translation.
The sequence of amino acids in a polypeptide chain determines its final three-dimensional structure and function.
Peptide bonds between amino acids are formed through a dehydration synthesis reaction.
Polypeptide chains can undergo post-translational modifications, such as phosphorylation or glycosylation, which affect their function.
Denaturation can unravel polypeptide chains, leading to loss of protein function.
