Ingcaciso yeMveliso
Amanzi anzima (deuterium oxide) luhlobo lwamanzi aneathom zehydrogen ziyideuterium (2H okanye D, ekwaziwa ngokuba yihidrojeni enzima) kuneyona hydrogen-1 isotope eqhelekileyo (1H, ekwabizwa ngokuba yiprotium) eyenza uninzi lwehydrogen. kumanzi aqhelekileyo.Ubukho be-isotopu enzima ngakumbi inika amanzi iipropathi ezahlukeneyo zenyukliya, kunye nokwanda kobunzima bunika iipropati ezahlukeneyo zomzimba kunye neekhemikhali xa kuthelekiswa namanzi aqhelekileyo.
I-Deuterium yi-isotope ye-hydrogen enzima. Amanzi anzima aneathom zedeuterium kwaye asetyenziswa kwizixhobo zenyukliya. Amanzi ane-Semiheavy (i-HDO) axhaphake kakhulu kunamanzi anzima acwengileyo, ngelixa amanzi e-oksijini enzima exinene kodwa engenazo iimpawu ezizodwa. Amanzi ane-Tritiated ane-radioactive ngenxa yesiqulatho se-tritium.
Amanzi anzima aneempawu zomzimba ezahlukileyo kumanzi aqhelekileyo, anje ngokuba ngqindilili nge-10.6% kunye nendawo ephezulu yokunyibilika. Amanzi anzima awahlulwanga kangako kubushushu obunikiweyo, kwaye akanawo umbala oluhlaza kancinci wamanzi aqhelekileyo. Ngelixa ingenawo umohluko wencasa obalulekileyo, inokungcamla okuswiti kancinci. Amanzi anzima achaphazela iinkqubo zebhayoloji ngokuguqula i-enzymes, iibhondi ze-hydrogen, kunye nokuhlukana kweeseli kwi-eukaryotes. Inokuba yingozi kwi-multicellular organisms ekugxininiseni ngaphezu kwe-50%. Nangona kunjalo, ezinye iiprokaryotes ezifana neebhaktheriya zinokuphila kwindawo enzima ye-hydrogen. Amanzi anzima anokuba yityhefu ebantwini, kodwa isixa esikhulu siya kufuneka ukuze kwenzeke ityhefu.
