Compound	Description
hydronium ion
hydrogen sulfide	A 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)
Cysteine	A thiol-containing non-essential amino acid that is oxidized to form CYSTINE.
Coenzyme A
Acetyl Coenzyme A	Acetyl 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.
