Title: Ubiquinones
Synonyms: Coenzymes Q; mitoquinones; SA; Q-275
Literature References: A group of lipid-soluble benzoquinones involved in electron transport in mitochondria, i.e., in the oxidation of succinate or reduced nicotine adenine dinucleotide (NADH) via the cytochrome system. Occurs in the majority of aerobic organisms, from bacteria to higher plants and animals. Ubiquinone structures, analogous to the menaquinones, q.v., are based on the 2,3-dimethoxy-5-methylbenzoquinone nucleus with a variable terpenoid side chain contg one to twelve mono-unsaturated trans-isoprenoid units with 10 units being the most common in animals. According to the existing dual system of nomenclature the compds can be described as: coenzyme Qn in which n = 1-12, or ubiquinone(x) in which x designates the total number of carbon atoms in the side chain and can be any multiple of 5. Differences in properties are due to the difference in length of the side chain. Naturally occurring members are the coenzymes Q6-Q10. The entire series has been prepd synthetically.
