ohun ti o jẹ Nicotinamide adenine dinucleotide(NAD +)?

Nicotinamide adenine dinucleotide (NAD) jẹ cofactor kan ti o ṣe iranlọwọ iṣelọpọ ti a rii ni gbogbo awọn sẹẹli ngbe. O wa ni awọn ọna meji, oxidized (NAD +) ati dinku (NADH).

Coenzyme NAD +, fọọmu oxidized ti NAD, ni akọkọ ṣe awari ni ọdun 1906 nipasẹ awọn onimọ-biochemist ti ilu Britain Arthur Harden ati William John Young. NAD + jẹ iṣelọpọ nipasẹ awọn ipa ọna gbigbepọ meji, eyiti o le ṣe lati ọna opopona de novo amino acid, tabi le ṣe iṣelọpọ nipasẹ atunlo awọn ohun elo ti iṣaju iṣaaju (bii nicotinamide) pada si ọna igbala ti NAD +. O jẹ ẹya iparun pyridine pataki ati ṣiṣẹ bi cofactor pataki ati aropo fun ọpọlọpọ awọn ilana ilana sẹẹli bọtini ti o ni irawọ-ara oxidative ati iṣelọpọ ATP, atunṣe DNA, ilana ilana eegun ti ikosile pupọ, ami ifihan kalsia iṣan ati iṣẹ Immunological.

NAD + jẹ ohun elo itẹwọgba gbigba elekitironi ni ifoyina nipa ẹda. O gba awọn elekitiro lati awọn ohun alumọni miiran ati dinku. O tun ṣe bi coenzyme ti itankale hydride ati aropo ti o jẹ NAD (+) polymerase, ati ṣe apẹrẹ coenzyme redox pẹlu dinku β-nicotinamide adenine dinucleotide (NADH). NAD (R) jẹ ribosylation ADP-ribose ninu ADP-A. O tun jẹ ipilẹṣẹ si cyclic ADP-ribose (ADP-ribosyl cyclase).

Gẹgẹbi ifasita ninu iṣelọpọ ara, NAD (R) tun ṣe ipa ninu awọn aati gbigbe gbigbe adenosine diphosphate (ADP) -ribose ti o kan diadenylate (ADP-ribose) polymerase ati ọpọlọpọ awọn ilana enzymu miiran. O le ni aabo fun NAD lati ṣe idiwọ tabi dinku suga, akàn ati awọn aisan miiran ti o ni ibatan ọjọ-ori.
