Discovery of ubiquinone (coenzyme Q) and an overview of function.
Details of the discovery of ubiquinone (coenzyme Q) are described in the context of research on mitochondria in the early 1950s. The importance of the research environment created by David E. Green to the recognition of the compound and its role in mitochondria is emphasized as well as the dedicated work of Karl Folkers to find the medical and nutritional significance. The development of divers...
متن کاملCoenzyme Q and mitochondrial disease.
Coenzyme Q(10) (CoQ(10)) is an essential electron carrier in the mitochondrial respiratory chain and an important antioxidant. Deficiency of CoQ(10) is a clinically and molecularly heterogeneous syndrome, which, to date, has been found to be autosomal recessive in inheritance and generally responsive to CoQ(10) supplementation. CoQ(10) deficiency has been associated with five major clinical phe...
متن کاملCoenzyme q and the respiratory chain: coenzyme q pool and mitochondrial supercomplexes.
Two alternative models of organization of the mitochondrial electron transport chain (mETC) have been alternatively favored or questioned by the accumulation evidences of different sources, the solid model or the random collision model. Both agree in the number of respiratory complexes (I-IV) that participate in the mETC, but while the random collision model proposes that Complexes I-IV do not ...
متن کاملCoenzyme Q 10 : a Review
Ubiquinone or Co Q(10) is essentially a vitamin like substance and is a cofactor of an enzyme. It is an integral part of the memberanes of mitocondria where it is involved in the energy production. It is a nutrient necessary for the function of every cell of the body especially vital organs of the body like heart, liver, brain etc. Studies have shown that coenzyme Q(10) alters the natural histo...
متن کاملEndogenous synthesis of coenzyme Q in eukaryotes.
Coenzyme Q (Q) functions in the mitochondrial respiratory chain and serves as a lipophilic antioxidant. There is increasing interest in the use of Q as a nutritional supplement. Although, the physiological significance of Q is extensively investigated in eukaryotes, ranging from yeast to human, the eukaryotic Q biosynthesis pathway is best characterized in the budding yeast Saccharomyces cerevi...
