BACKGROUND: Many well-documented biochemical processes lack a molecular mechanism. Examples are: how ATP hydrolysis and an enzyme contrive to perform work. such as active transport; how peptides are formed from amino acids and DNA from nucleotides; how proteases cleave peptide bonds. how bone mineralses; how enzymes distinguish between sodium and potassium; how chirality of biopolymer... https://www.spidertattooz.com/Color-Club-Nail-Lacquer-Pure-Energy-0-5-oz-p9629/
