Many variants of each are known. Proteins are characterized by amide linkages (-N(H)-C(O)-) formed by the condensation of amino acids. The sequence of the amino acids in the polypeptide backbone is known as the primary structure of the protein. Like al…

Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group. A typical fatty acid contains 12–18 carbons, though some may have as few as 4 or as many as 36.
WebJan 17, 2024 · Abstract. Three chiral carbonyl hypoiodites, R–C (O)OI, have been prepared from N-protected ( S )-valine to give the ligand-stabilised ( S )-valinoyl hypoiodite complexes with 4-dimethylaminopyridine, 4-pyrrolidinopyridine, and 4-morpholinopyridine as the stabilising ligands. The identity of the complexes was established by NMR ( 1 H, 13 C, 1 ...
