Amino acids are the building blocks of protein. The sequence of life combining to form protein structures including muscle tissue, enzymes and hormones.
What makes amino acids, which combine to form proteins, different from other macronutrients (carbohydrates and fats)? They all contain an amino group (NH2) attached to an acidic carboxyl group (COOH) and an organic side group (R). Carbohydrates and fats do not contain an amino group.
Amino acids are a remarkable and essential component of our genetic code and are present in every single cell in our bodies. Thus, amino acids are involved in a number of metabolic pathways that effect the breakdown of food and growth.
