different types of proteins and amino acids
Amino acids are organic compounds which contain at least one amino group (-NH2) and a carboxy (-COOH) group. In the human genome, 20 amino acids are created to build proteins and therefore termed proteinogen. Besides this, there are approximately 250 amino acids which do not form proteins.hese are: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Arginine and histidine form the group of so-called semi-essential amino acids. They have to be consumed in the diet under certain circumstances. The ten non-essential amino acids are able to be produced in the body.
