| hydronium ion | |
| succinic acid | A water-soluble, colorless crystal with an acid taste that is used as a chemical intermediate, in medicine, the manufacture of lacquers, and to make perfume esters. It is also used in foods as a sequestrant, buffer, and a neutralizing agent. (Hawley's Condensed Chemical Dictionary, 12th ed, p1099; McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed, p1851) |
| cysteine | A thiol-containing non-essential amino acid that is oxidized to form CYSTINE. |
| methionine | A sulfur-containing essential L-amino acid that is important in many body functions. |
