Intangiriro

Uburyohe bwa acide uburyohe, butagira impumuro nziza, gusa ibimenyetso bya sulfite. Ni aside amine ikoreshwa ningirabuzimafatizo zitandukanye kugirango irinde ibintu byangiza no kongera imbaraga mu nyamaswa n’ibimera. Ninimwe muri acide zirenga 20 za amino zigize proteyine, kandi niyo aside aside yonyine ifite sulfhydryl ikora (-SH).
