Amino Acid IV

Amino acids are the building blocks of the human body, making up proteins that form tissues, organs, muscles, skin, and hair. Amino acids are also the precursors of enzymes and neurotransmitters that regulate almost all metabolic processes, making them essential for human health. The presence of nitrogen in amino acids distinguishes proteins from fats and carbohydrates that your body uses. Without amino acids, life would not exist.
