Amino acids
Proteins are a class of biologically significant substance. They are important to virtually all processes in living systems. A few of acids are hormones that offer as chemical messengers that coordinate specific biochemical activities. Few proteins give out to transport the substances by the organism. Proteins are as well available in toxins (poisonous materials) aqlso in antibiotics. All the proteins are making up of many amino acid units associated together into a large chain. An amino acid is a bifunctional organic molecule which consists of both a carboxyl group set, -COOH, also an amine group set, -NH2.
