Amino Acids, Neutral

Amino acids are a type of organic compound composed of nitrogen, carbon, hydrogen and oxygen that link together to form "building blocks" of proteins. There are 20 standard amino acids, of which 9 are essential for humans and must be obtained through the diet. Neutral amino acids play an important role in protein synthesis and in energy metabolism, and are also essential for the formation and repair of cells, tissues and organs. They are also involved in many biochemical pathways, allowing cells to regulate a wide variety of metabolic processes in the body. As they are water-soluble, they are easily absorbed from the gut, making them a valuable component of a balanced diet.
