Primary bonding force that crosslinks chains
WebLecture 5. L. Chasin. So the long chain of a polypeptide does not assume a random coil configuration in space, but, amazingly, folds into a precisely defined 3-dimensional shape each and every time. That is, each of the billions of protein molecules of a given kind, with a specific name and sequence, are superimposable, atom for atom. WebThe simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain. For example, the hormone insulin has two polypeptide …
