Compounds (5)

CompoundDescription
hydronium ion
hydrogen sulfideA flammable, poisonous gas with a characteristic odor of rotten eggs. It is used in the manufacture of chemicals, in metallurgy, and as an analytical reagent. (From Merck Index, 11th ed)
CysteineA thiol-containing non-essential amino acid that is oxidized to form CYSTINE.
Coenzyme A
Acetyl Coenzyme AAcetyl CoA participates in the biosynthesis of fatty acids and sterols, in the oxidation of fatty acids and in the metabolism of many amino acids. It also acts as a biological acetylating agent.
