amino acid

An amino acids is an organic compound, and it serves as a building block for proteins.

Each amino acid contains an amino group and a carboxylic acid group. Amino acids are important because they make up proteins, which are a vital part of your diet. When you consume food with amino acids, it turns them into proteins which are a source of energy. There are amino acids in food like bacon and eggs, which is why you get a burst of energy after eating them.
