Glycine does not have … NettetAlthough most amino acids can exist in both left and right handed forms, Life on Earth is made of left handed amino acids, almost exclusively. No one knows why this is the case. However, Drs. John Cronin and Sandra Pizzarello have shown that some of the amino acids that fall to earth from space are more left than right.
