Igizwe n’ivyuma bita BPG canke DPG mu congereza, ni ikintu gihambaye gitera hemoglobine.

Ugufatanya kwa 2,3-DPG mu ngirabuzimafatizo zitukura n’imiti y’ibinyabiziga bigumaho birahagarara neza, ivyo bikaba bigabanya ubushobozi bwa hemoglobine ku ndwara ya O2 no gutuma habaho ugusenyuka kwa O2 na hemoglobine. Cane cane iyo amaraso aciye mu nyama, kuba hariho 2,3-DPG mu ngingo z’amaraso zitukura birashobora kwongerera cane O2 ku nkenegwa z’imitsi. Ikindi, abarwayi bafise ubumuga bukomeye bw’umubiri bafise ingorane yo guhumanya amahaha n’abantu basanzwe barashobora guhindura imitsi mu guhindura ivyiyumviro vya 2,3-DPG mu ngingo z’amaraso zitukura iyo ivyuka kuva ku rugero rw’ikiyaga bikaja ku burebure bwinshi canke uburebure bw’uburebure bwinshi mu kiringo gito. Uronke igitigiri ca O2.

Mu gihe BPG iriho, umwuka w’ikirere ushobora kugaragazwa n’iyi nkuru ikurikira:

HbBPG + 4O2 → Hb(O2)4 + BPG (Iciyumviro: Iyi ni inyishu ishobora guhindurwa)

Ishami 2,3-diphosphoglycerate Uruhara ruhambaye rwa 2,3-diphosphoglycerate (2,3-DPG) mu ngingo z’amaraso zitukura ni ugutunganya igikorwa ca O2 c’amaraso y’umubiri.

Itandukaniro hagati y’indwara y’utugingo ngengabuzima dutukura n’izindi ngingo ni uguhingura 2,3-DPG. Ibiri muri 2,3-PDG ni vyo vyari hejuru cane mu gice c’imbere c’umubiri (mu maraso y’umubiri: ibiri muri 2,3-PD vyari incuro 177 n’incuro 239 z’ivyo bita 3-fosphoglycerate). Ivyo biva ku kuba hariho umugera wa diphosphoglycerate (DPG) na 2,3-DPG phosphatase mu ngingo z’amaraso zitukura. Ivyo bisubizo bifatwa n’izo enzyme zibiri ntibishobora gusubirwamwo. Mu bihe bisanzwe, ingaruka mbi z’inyishu z’ibice 2,3-diphosphoglycerate ku mutase ya DPG ni nyinshi kuruta guhagarika 3-fosphoglycerate, rero glucose mu turemangingo tw’amaraso dutukura iracari ahanini glycolysis kugira ngo haboneke aside ya lactique. Kubera igikorwa gito c’ivyuma 2,3-DPG phosphatase, 2,3-DPG ni nini kuruta gusenyuka, bikaba bituma habaho urugero rwo hejuru rwa 2,3-PD mu ngingo z’amaraso zitukura.
