Individual Amino Acids and Their Abbreviations

Glycine (Gly): Simplest amino acid, non-polar
Alanine (Ala): A non-polar amino acid, commonly involved in protein structure
Valine (Val): Non-polar, essential amino acid, involved in muscle metabolism
Leucine (Leu): Essential, non-polar amino acid, important for protein synthesis and muscle repair
Isoleucine (Ile): Essential amino acid, non-polar, critical for energy regulation
Methionine (Met): Non-polar, contains sulfur, initiates protein synthesis
Phenylalanine (Phe): Aromatic non-polar amino acid, precursor to neurotransmitters
Tryptophan (Trp): Precursor to serotonin, non-polar
Proline (Pro): Unique structure, contributes to the formation of collagen; non-polar
Serine (Ser): Polar amino acid, involved in metabolic processes and enzyme regulation
Threonine (Thr): Polar, essential amino acid, involved in protein synthesis and immune function
Cysteine (Cys): Contains sulfur, important for forming disulfide bonds in proteins, polar
Tyrosine (Tyr): Precursor to hormones like thyroid hormones; polar
Asparagine (Asn): Polar, involved in nitrogen transport and metabolism
Glutamine (Gln): Most abundant amino acid in blood, polar, vital for immune function
Aspartic Acid (Asp): Electrically charged, plays a role in metabolic processes
Glutamic Acid (Glu): Electrically charged, functions as a neurotransmitter
Lysine (Lys): Essential, positively charged, important for protein synthesis and hormone production
Arginine (Arg): Electrically charged, precursor to nitric oxide, important for blood flow
Histidine (His): Electrically charged, essential for growth and tissue repair; involved in hemoglobin's function.
