Nicotinic acid
Nicotinic acid is an odorless white crystalline powder with a feebly acid taste. pH (saturated aqueous solution) 2.7. pH (1.3\\\\\% solution) 3-3.5. (NTP, 1992) Nicotinic acid is a pyridinemonocarboxylic acid that is pyridine in which the hydrogen at position 3 is replaced by a carboxy group. It has a role as an antidote, an antilipemic drug, a vasodilator agent, a metabolite, an EC 3.5.1.19 (nicotinamidase) inhibitor, an Escherichia coli metabolite, a mouse metabolite, a human urinary metabolite and a plant metabolite. It is a vitamin B3, a pyridinemonocarboxylic acid and a pyridine alkaloid. It is a conjugate acid of a nicotinate. Niacin is a B vitamin used to treat vitamin deficiencies as well as hyperlipidemia, dyslipidemia, hypertriglyceridemia, and to reduce the risk of myocardial infarctions. Nicotinic acid is a metabolite found in or produced by Escherichia coli (strain K12, MG1655). Niacin is a Nicotinic Acid. Niacin, also known as nicotinic acid and vitamin B3, is a water soluble, essential B vitamin that, when given in high doses, is effective in lowering low density lipoprotein (LDL) cholesterol and raising high density lipoprotein (HDL) cholesterol, which makes this agent of unique value in the therapy of dyslipidemia. Niacin can cause mild-to-moderate serum aminotransferase elevations and high doses and certain formulations of niacin have been linked to clinically apparent, acute liver injury which can be severe as well as fatal. Niacin is a water-soluble vitamin belonging to the vitamin B family, which occurs in many animal and plant tissues, with antihyperlipidemic activity. Niacin is converted to its active form niacinamide, which is a component of the coenzymes nicotinamide adenine dinucleotide (NAD) and its phosphate form, NADP. These coenzymes play an important role in tissue respiration and in glycogen, lipid, amino acid, protein, and purine metabolism. Although the exact mechanism of action by which niacin lowers cholesterol is not fully understood, it may act by inhibiting the synthesis of very low density lipoproteins (VLDL), inhibiting the release of free fatty acids from adipose tissue, increasing lipoprotein lipase activity, and reducing the hepatic synthesis of VLDL-C and LDL-C. Nicotinic acid, also known as niacin or vitamin B3, is a water-soluble vitamin whose derivatives such as NADH, NAD, NAD+, and NADP play essential roles in energy metabolism in the living cell and DNA repair. The designation vitamin B3 also includes the amide form, nicotinamide or niacinamide. Severe lack of niacin causes the deficiency disease pellagra, whereas a mild deficiency slows down the metabolism decreasing cold tolerance. The recommended daily allowance of niacin is 2-12 mg a day for children, 14 mg a day for women, 16 mg a day for men, and 18 mg a day for pregnant or breast-feeding women. It is found in various animal and plant tissues and has pellagra-curative, vasodilating, and antilipemic properties. The liver can synthesize niacin from the essential amino acid tryptophan (see below), but the synthesis is extremely slow and requires vitamin B6; 60 mg of tryptophan are required to make one milligram of niacin. Bacteria in the gut may also perform the conversion but are inefficient. A water-soluble vitamin of the B complex occurring in various animal and plant tissues. It is required by the body for the formation of coenzymes NAD and NADP. It has PELLAGRA-curative, vasodilating, and antilipemic properties.

C8H13N2O5P (248.05620580000001)
Pyridoxamine 5-phosphate belongs to the class of organic compounds known as pyridoxamine 5-phosphates. These are heterocyclic aromatic compounds containing a pyridoxamine that carries a phosphate group at the 5-position. Vitamin B6 is a water-soluble compound that was discovered in 1930s during nutrition studies on rats. The vitamin was named pyridoxine to indicate its structural homology to pyridine. Later it was shown that vitamin B6 could exist in two other, slightly different, chemical forms, termed pyridoxal and pyridoxamine. All three forms of vitamin B6 are precursors of an activated compound known as pyridoxal 5-phosphate (PLP), which plays a vital role as the cofactor of a large number of essential enzymes in the human body. Vitamin B6 is a water-soluble vitamin. The three major forms of vitamin B6 are pyridoxine (also known as pyridoxol), pyridoxal, and pyridoxamine, which are all converted in the liver to pyridoxal 5-phosphate (PLP) a cofactor in many reactions of amino acid metabolism. PLP also is necessary for the enzymatic reaction governing the release of glucose from glycogen. Vitamin B6 is a water-soluble compound that was discovered in 1930s during nutrition studies on rats.

Pyrimidine
Pyrimidine is a heterocyclic aromatic organic compound similar to benzene and pyridine, containing two nitrogen atoms at positions 1 and 3 of the six-member ring. Pyrimidines are heterocyclic, six-membered, nitrogen-containing carbon ring structures, with uracil, cytosine and thymine being the basal structures of ribose-containing nucleosides (uridine, cytidine and thymidine respectively), or deoxyribose-containing deoxynucleosides, and their corresponding ribonucleotides or deoxyribonucleotides. Pyrimidines serve essential functions in human metabolism as ribonucleotide bases in RNA (uracil and cytosine), and as deoxyribonucleotide bases in DNA (cytosine and thymine), and are linked by phosphodiester bridges to purine nucleotides in double-stranded DNA, in both the nucleus and the mitochondria. Pyrimidine activated sugars are also involved in polysaccharide and phospholipid synthesis, glucuronidation in detoxification processes, glycosylation of proteins and lipids and in the recently identified novel endothelium-derived vasoactive dinucleotides. Pyrimidines are synthesized de novo from simple precursors. Synthesis occurs in six steps, with cellular compartmentalization of specific steps in the cytosol or mitochondria, enabling changes in metabolic rate with need. Pyrimidine synthesis differs from purine synthesis, in that the single pyrimidine ring is assembled first and is then linked to ribose phosphate to form UMP. The enzymes that catalyse UMP synthesis, CAD [carbamoylphosphate synthetase II (CPSII), aspartate transcarbamoylase (ATCasea) and dihydroorotase (DHOase)], dihydroorotate dehydrogenase (DHODH) and uridine monophosphate synthase (UMPS), are encoded by only three genes - CAD, DHODH and UMPS (chromosomal locations 2p21, 16q22 and 3q13, respectively).
