Classification of Amino Acids The 20 amino acids essential for protein synthesis can be classified in several ways. 1. Based on Chemical Structure: Glycogenic amino acids: These amino acids are used for the formation of glucose. Ketogenic amino acids: These amino acids can be synthesized into ketone bodies. Glucogenic and ketogenic amino acids: Two amino acids, leucine and lysine, can be converted into both glucose and ketone bodies. 2. Based on the Metabolic Fate: Essential amino acids: These amino acids cannot be synthesized by the body and must be obtained from the diet. Non-essential amino acids: These amino acids can be synthesized by the body. Glycogenic and Ketogenic Amino Acids Glycogenic and Ketogenic Amino Acids: These amino acids serve as precursors for the synthesis of glucose or ketone bodies. Ex: Isoleucine, phenylalanine, tryptophan, tyrosine, threonine Based on the nutritional requirement, amino acids can be classified into two classes: Essential or Indispensable Amino Acids: These amino acids cannot be synthesized in the body and must be supplied through the diet. They are required for growth and maintenance of the individual. Ex: Histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine Importance of Essential Amino Acids: Imbalance of amino acids can lead to protein synthesis and serious health consequences.
