Detailed explanation-1: -When connected together by a series of peptide bonds, amino acids form a polypeptide, another word for protein.
Detailed explanation-2: -Protein folding is essential for a polypeptide chain to acquire its proper structure and function. Protein folding is assisted by HSP called chaperones. Multimeric complexes that form hollow structures, called chaperonins, also participate in protein folding.
Detailed explanation-3: -Primary structure. The simplest level of protein structure, primary structure, is simply the sequence of amino acids in a polypeptide chain.
Detailed explanation-4: -When folding, two types of structures usually form first. Some regions of the protein chain coil up into slinky-like formations called “alpha helices, ” while other regions fold into zigzag patterns called “beta sheets, ” which resemble the folds of a paper fan.
