Madzi olemera (deuterium oxide) ndi madzi omwe maatomu awo a haidrojeni onse ndi deuterium (2H kapena D, omwe amadziwikanso kuti heavy hydrogen) osati hydrogen-1 isotope (1H, yotchedwanso protium) yomwe imapanga haidrojeni yambiri. m'madzi abwinobwino.Kupezeka kwa isotopu yolemera kumapatsa madzi zinthu zosiyanasiyana za nyukiliya, ndipo kuchuluka kwa misa kumapereka kusiyana pang'ono kwakuthupi ndi mankhwala poyerekeza ndi madzi abwinobwino.
Deuterium ndi isotope yolemera ya haidrojeni. Madzi olemera amakhala ndi ma atomu a deuterium ndipo amagwiritsidwa ntchito mu zida za nyukiliya. Madzi a Semiheavy (HDO) ndiofala kwambiri kuposa madzi olemera kwambiri, pomwe madzi okosijeni olemera amakhala ochulukirapo koma alibe mawonekedwe apadera. Madzi a tritiated amakhala ndi radioactive chifukwa cha tritium.
Madzi olemera ali ndi mawonekedwe osiyana ndi madzi wamba, monga kukhala 10.6% deser komanso kukhala ndi malo osungunuka kwambiri. Madzi olemera samasiyanitsidwa pang'ono ndi kutentha komwe kumaperekedwa, ndipo alibe mtundu wa buluu pang'ono wamadzi wamba. Ngakhale ilibe kusiyana kwakukulu kwa kukoma, imatha kukoma pang'ono. Madzi olemera amakhudza machitidwe achilengedwe mwa kusintha ma enzyme, ma hydrogen bond, ndi kugawanika kwa maselo mu eukaryotes. Zitha kukhala zakupha kwa zamoyo zambiri zama cell pazambiri zopitilira 50%. Komabe, ma prokaryotes ena monga mabakiteriya amatha kukhala m'malo olemera a haidrojeni. Madzi olemera amatha kukhala oopsa kwa anthu, koma pakufunika kuti chiphe chichitike.
