英语词汇“nicotinamide adenine dinucleotide”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

nicotinamide adenine dinucleotide n. a coenzyme that participates in tissue respiration and other metabolic reactions, acting as an electron acceptor (by the addition of a hydride ion to the pyridine ring of the nicotinamide) during the oxidation of a substrate, and producing a reduced form which is then oxidized in another reaction; abbreviated NAD (also as the oxidized form NAD⁺; as the reduced form NADH).

ΚΠ

1960 Science 25 Nov. 1549/2 To complete the scheme we should expect NAD for nicotinamide-adenine dinucleotide, thus: FMN, NMN, FAD, NAD.

1984 E. Holtzman & A. B. Novikoff Cells & Organelles (ed. 3) i. iii. 37 In four of the steps we are considering, two hydrogen atoms are removed from substrates; from these, two electrons and one proton are transferred to NAD (nicotinamide adenine dinucleotide), with an additional H⁺ being freed.

1997 New Scientist 20 Dec. 48/1 The enzymes which destroy ethanol and methanol need the assistance of two ‘helper’ substances. The first, nicotinamide adenine dinucleotide (NAD), is responsible for taking away the hydrogen atoms snipped out of ethanol and methanol.
