What is Amino Acid?
Amino acids are organic molecules containing both an amino group (–NH₂) and a carboxyl group (–COOH) attached to the same carbon atom (the alpha carbon). They are the fundamental building blocks of proteins, with 20 standard amino acids encoded by the genetic code. The sequence of amino acids in a polypeptide chain determines the protein's three-dimensional structure and function.

Amino acids are organic molecules containing both an amino group (–NH₂) and a carboxyl group (–COOH) attached to the same carbon atom (the alpha carbon). They are the fundamental building blocks of proteins, with 20 standard amino acids encoded by the genetic code. The sequence of amino acids in a polypeptide chain determines the protein's three-dimensional structure and function.
Amino acids are the monomeric building blocks of proteins and enzymes. They are used in nutritional supplements, pharmaceutical synthesis, food flavouring (glutamate as MSG), and as chiral catalysts in asymmetric synthesis. Several serve as precursors to neurotransmitters (e.g., tyrosine → dopamine)…
Dietary amino acids are generally safe. Excessive supplementation with individual amino acids can cause metabolic imbalances. Phenylketonuria (PKU) is a genetic condition where phenylalanine cannot be metabolised properly, requiring dietary restriction.
