| hydronium ion | |
| Tyrosine | A non-essential amino acid. In animals it is synthesized from PHENYLALANINE. It is also the precursor of EPINEPHRINE; THYROID HORMONES; and melanin. |
| Valine | A branched-chain essential amino acid that has stimulant activity. It promotes muscle growth and tissue repair. It is a precursor in the penicillin biosynthetic pathway. |
| Arginine | An essential amino acid that is physiologically active in the L-form. |
| Asparagine | A non-essential amino acid that is involved in the metabolic control of cell functions in nerve and brain tissue. It is biosynthesized from ASPARTIC ACID and AMMONIA by asparagine synthetase. (From Concise Encyclopedia Biochemistry and Molecular Biology, 3rd ed) |
| chlorine | An element with atomic symbol Cl, atomic number 17, and atomic weight 35, and member of the halogen family. |
| glutamic acid | A non-essential amino acid naturally occurring in the L-form. Glutamic acid is the most common excitatory neurotransmitter in the CENTRAL NERVOUS SYSTEM. |
| cysteine | A thiol-containing non-essential amino acid that is oxidized to form CYSTINE. |
| Cystine | A covalently linked dimeric nonessential amino acid formed by the oxidation of CYSTEINE. Two molecules of cysteine are joined together by a disulfide bridge to form cystine. |
| aspartic acid | One of the non-essential amino acids commonly occurring in the L-form. It is found in animals and plants, especially in sugar cane and sugar beets. It may be a neurotransmitter. |
| Glutamine | A non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes. It is synthesized from GLUTAMIC ACID and AMMONIA. It is the principal carrier of NITROGEN in the body and is an important energy source for many cells. |
| glycine | A non-essential amino acid. It is found primarily in gelatin and silk fibroin and used therapeutically as a nutrient. It is also a fast inhibitory neurotransmitter. |
| potassium | An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE. |
| racemethionine | A preparation of METHIONINE that includes a mixture of D-methionine and L-methionine isomers. |
| Sodium | A member of the alkali group of metals. It has the atomic symbol Na, atomic number 11, and atomic weight 23. |
| Proline | A non-essential amino acid that is synthesized from GLUTAMIC ACID. It is an essential component of COLLAGEN and is important for proper functioning of joints and tendons. |
| Serine | A non-essential amino acid occurring in natural form as the L-isomer. It is synthesized from GLYCINE or THREONINE. It is involved in the biosynthesis of PURINES; PYRIMIDINES; and other amino acids. |
| polyhistidine | RN refers to (L)-isomer; polyhistidine fusion tag, usually consisting of six consecutive histidines added to the end of a protein, allows easy purification with metal-chelate resins; |
| Leucine | An essential branched-chain amino acid important for hemoglobin formation. |
| endolysin | |
| phenylalanine | An essential aromatic amino acid that is a precursor of MELANIN; DOPAMINE; noradrenalin (NOREPINEPHRINE), and THYROXINE. |
| d-aspartic acid | The D-isomer of ASPARTIC ACID. |
