Amino acids are organic compounds fundamental to protein formation, play vital roles in diverse biological functions within the body, such as facilitating protein synthesis, enzyme activity, and hormone regulation.

As essential components of the human body, amino acids can be acquired through dietary sources. However, despite obtaining a significant portion of amino acids from food, there remains a fraction that cannot be sufficiently supplied through daily dietary intake alone. In such cases, it becomes imperative to supplement one’s diet to address this deficiency and ensure adequate amino acid levels. Therefore, amino acids can usually be divided into three categories.

Types of Amino Acids

  • Essential Aminos: essential amino acids are unable to be synthesized by the body and must be obtained from the diet, which can be also called naturally occurring amino acids. Examples include leucine, isoleucine, valine, lysine, methionine, and histidine.
  • Non-essential Amino Acids: These are amino acids that the body can synthesize from other compounds and do not need to be obtained from the diet. Examples include alanine, arginine, asparagine, aspartic acid, and tyrosine.
  • Conditionally Essential Amino Acids: conditional amino acid is normally non-essential but become essential under certain conditions, such as illness, stress, or during periods of rapid growth and development. Examples include arginine, cysteine, glutamine, tyrosine, and serine.

Functions of Amino Acids

  • Protein Synthesis: Amino acids play a crucial role in the synthesis of proteins, which are essential for growth, repair, and maintenance of tissues such as muscles, skin, hair, and organs.
  • Enzyme Production: Many enzymes, which are catalysts for biochemical reactions in the body, are composed of amino acids. These enzymes facilitate various metabolic processes, ensuring proper functioning of cells and organs.
  • Hormone Regulation: Certain amino acids serve as precursors for the synthesis of hormones and neurotransmitters, which play key roles in regulating mood, appetite, sleep, and other physiological functions.
  • Immune Function: Some amino acids, such as glutamine and arginine, are important for supporting immune function and maintaining a healthy immune response to pathogens and foreign invaders.
