These amino acids are normally non-essential, but become essential during times of physiological stress. Ketogenic Glycogenic Glycogenic amino acids have the ability to be converted into glucose. Aspartic Acid Cysteine Glutamic Acid Glutamine Glycine Histidine Methionine Proline Serine Ketogenic Ketogenic amino acids have the ability to be converted into ketones. The process of ketone formation involves both the breakdown of fats and the formation of a source of energy. The 40,000 different kinds of protein in the human body are made up of 20 amino acids.
Taurine is made from methionine and cysteine.
Hydroxyproline and Hydroxylysine, both minor amino acids, are made from proline and lysine. Aliphatic Alanine Glycine Isoleucine Leucine Proline Valine 2. Aromatic Phenylalanine Tryptophan Tyrosine 3. Acidic Aspartic Acid Glutamic Acid 4. Basic Arginine Histidine Lysine 5.
