Other enzymes contain a nonprotein component called a cofactor A nonprotein component of an enzyme that is necessary for an enzyme’s proper functioning. Coenzyme Q10 plays a major role in cellular energy production by breaking down carbohydrates and fats into cellular energy known as Adenosine Triphosphate (ATP). Menaquinones (vitamin K 2) are primarily of microbial origins and thus commonly found in fermented foods, such as cheese, curds, and natto (fermented soybeans). Vitamin K is a coenzyme for glutamate carboxylase, which mediates the conversion of glutamate to gamma-carboxyglutamate (Gla). Kirke PN, Molloy AM, Daly LE, Burke H, Weir DG, Scott JM. 2001 Jun;47(6):1094-101. So magnesium would be a great example of a mineral co-factor that an enzyme like DNA polymerase would use. Your cells use CoQ10 for growth and maintenance.. Levels of CoQ10 in your body decrease as you age.CoQ10 levels have also been found to be lower in people with certain conditions, such as heart disease, and in those who take cholesterol-lowering drugs called statins.

Your heart works hard to supply a steady flow of blood throughout your body, providing oxygen and nutrients to tissues along the way. In 1974, scientists at three laboratories discovered the function for vitamin K as a cofactor. These compounds contain the rare element cobalt. Vitamin K 2. Vitamin K is the coenzyme of the carboxylase enzyme and acts in its reduced hydroquinone form. Welcome To My presentation 2. Grain processing removes much of the thiamine content, so in many countries cereals and flours are enriched with thiamine. Clin Chem.

As a class, quinones act as important electron donors and acceptors in a variety of biological processes. In contrast to many plants, fungi, and bacteria, humans cannot produce riboflavin or vitamin B2, and thus require it as a dietary supplement. Now, not all minerals act only as co-factors. Vitamin K acts as a coenzyme of carboxylase, catalyzing the carboxylation of several vitamin K dependent proteins. 370, Vol. Food sources of thiamine include whole grains, legumes, and some meats and fish. Improvements in the assay method based on the restoration of normal clotting time in hemorrhagic chicks led to the proposal that a lack of vitamin K caused a deficiency in prothrombin activity and that vitamin K might be some kind of coenzyme or prosthetic group required for active prothrombin (Schoenheyder, 1936).
