Protein macromolecules make up 50% of the dry weight of most cells. They are instrumental in everything an organism does. They have many functions including structural support, food storage, transport, hormonal coordinates, contractile movements, defence and enzyme aid. Proteins are very complex and are constructed from the same set of 20 monomers called amino acids. Amino acids consist of an asymmetrical carbon bonded to an amino group, hydrogen, an R group and a carboxyl group. Amino acids are joined together via a dehydration reaction, removing the hydroxyl group from the carboxyl end of one amino acid and a hydrogen from the amino g...
