| Amino Acids are the monomers that make up proteins by joining in [[Condensation_Reaction|condensation reactions]] to form [[Peptide_bond|peptide bonds]] between themselves. All amino acids have an alpha [[Carboxylic_acid|carboxylic acid]] group, an alpha [[Amine|amine]] group and a [[Hydrogen|hydrogen]] atom bonded to a central carbon along with a fourth variable group. This group varies in the 20 essential amino acids and generally allows amino acids to exhibit [[Stereoisomerism|sterioisomerism]] to create [[Optical_isomerism|optical isomers]] D and L. The only exception to this being the simplest amino acid [[Glycine|glycine]] with its variable group being another hydrogen atom. This prevents sterioisomerism as there aren't four different groups then bonded to the central carbon<sup>1</sup><sup></sup><sup></sup>.
