THE synthesis of phthaloyl amino-acids, using amino-acids as starting material, often proceeds under rather drastic conditions 1. Phthaloyl amino-acid esters, however, can be prepared under less d ...

The purpose of protein synthesis is simply to create a polypeptide -- a protein made out of a chain of amino acids. In a hair follicle cell, a protein called keratin is made. Lots of it.
