GENERAL KNOWLEDGE

Detailed explanation-1: -All of the water-soluble vitamins and two of the fat-soluble vitamins, A and K, function as cofactors or coenzymes. Coenzymes participate in numerous biochemical reactions involving energy release or catabolism, as well as the accompanying anabolic reactions (Figure 1).

Detailed explanation-2: -The vitamin that does not have a co-enzyme activity is tocopherol. also known as vitamin E, this is a light yellow oil, a fat-soluble vitamin, that is actually a family of compounds found in nature.

Detailed explanation-3: -Water soluble vitamins act as coenzymes when activating enzymes. Water soluble vitamins bind to the active site, which helps to facilitate enzyme activity.

Detailed explanation-4: -Vitamin B The coenzyme (5’-deoxyadenosyl) and methyl forms of this vitamin are essential for the recyling of the active folate coenzyme, for the methylation of homocysteine to form methionine, and for metabolism of propionate.
