Most people, when they criticize, whether they like it or hate it, they're talking about product. That's not art, that's the result of art. Art, to whatever degree we can get a handle on (I'm not sure that we really can) is a process. It begins in the heart and the mind with the eyes and hands.
Niacin (also known as vitamin B3 or nicotinic acid) is an organic compound with the formula C 6H 5NO 2 and, depending on the definition used, one of the 20 to 80 essential human nutrients.iacin cannot be directly converted to nicotinamide, but both compounds are precursors of the coenzymes nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP) in vivo. NAD converts to NADP by phosphorylation in the presence of the enzyme NAD+ kinase.
Niacin is a water-soluble B vitamin vitamin B3 - and the common name for 2 very different compounds: nicotinic acid and niacinamide. High doses of niacin (as nicotinic acid) can lower cholesterol levels (although the exact mechanism of action is still not known).owever, niacin is also made in the form of niacinamide-a form of vitamin B3 which, deliberately, is manufactured so that it will NOT cause dilation of the blood vessels-the flush so well known when using plain niacin.
