Ú Some nucleotides are coenzymes or other biologically active compounds Ú Each nucleotide is composed of a nitrogenous base, usually purine or pyrimidine; a carbohydrate, either ribose or deoxyribose; and a phosphoric acid residue Ú Each nucleotide is composed of a nitrogenous base, usually purine or pyrimidine; a carbohydrate, either ribose.

They ensure physiological functions, like blood clotting and metabolism, occur in an organism. These coenzymes can be produced from nucleotides such as adenosine, uracil, guanine, or inosine. Adenosine triphosphate (ATP) is an example of an essential non-vitamin.

soluble vitamins simply results in their excretion in the urine. Consumption of excess fat-soluble vitamins can lead to toxic conditions known as hypervitaminoses. The vitamin sources and the roles of the major coenzymes in metabolism, including both metabolite coenzymes and vitamin-derived coenzymes, are listed in Table IV. NAD+ and NADP+. Books. Physics. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Most of the coenzymes are nucleotides and are composed of vitamins Every coenzyme is a cofactor and every cofactor is not a coenzyme. Most of the coenzymes are nucleotides and are composed of vitamins. Coenzymes are the active constituents of enzymes. Coenzymes are organic molecules required for proper enzyme function and are often derived from vitamins. An enzyme lacking a cofactor or coenzyme is an apoenzyme; an enzyme with a bound cofactor or coenzyme is a holoenzyme. Competitive inhibitors regulate enzymes by binding to an enzyme’s active site, preventing substrate binding.   In contrast, water-soluble vitamins contain large numbers of electronegative oxygen and nitrogen atoms, which can engage in hydrogen bonding with water. Most water-soluble vitamins act as coenzymes or are required for the synthesis of coenzymes. The fat-soluble vitamins are important for a variety of physiological functions.

D. Baines, M. Brown, in Encyclopedia of Food and Health, Role of Nucleotides in Immune Response. Dietary nucleotides have been shown to be required for normal immune defense in adults. In two separate double-blind clinical studies, the patients fed a diet containing nucleotides had an improved immune function compared with patients receiving a nucleotide-free diet.

Vitamins and Coenzymes Part E Other nucleotides (formed from uracil, cytosine, guanine, and inosine) have also been found to act as coenzymes. For example Those coenzymes. 2 Water-Soluble Vitamins Riboflavin (Vitamin B 2) and Related Coenzymes Nicotinic Acid, Nicotinamide, and Related Coenzymes Pantothenic Acid and Coenzyme A Pyridoxine (Vitamin B 6) Biotin Vitamin B 12 L-Ascorbic Acid (Vitamin C) Adenosine Triphosphate and Related Nucleotides The most common sources of coenzymes are dietary vitamins (Figure ). Some vitamins are precursors to coenzymes and others act directly as coenzymes. Vitamin C is a coenzyme for multiple enzymes that take part in building the important connective tissue component, collagen.
