Imikoreshereze y'ibicuruzwa
L-valine ni kirisiti yera cyangwa ifu ya kristaline, fist uburyohe bworoshye noneho uburyohe bukaze. Kubora kubusa muri acide formique, gushonga mumazi, muburyo budashonga muri Ethanol na ether. Kandi ni aside amine yingenzi ikenewe kugirango sysytem ya nervice yoroshye hamwe nibikorwa byubwenge. Nimwe muri bitatu byamashami yubushinwa Amino Acide (BCAAs). L. ibice byose byumubiri bikeneye. Valine irashobora gukoreshwa nkintungamubiri zintungamubiri, irashobora gufatanyirizwa hamwe nibindi byingenzi byinjizwamo aside amine, gutegura aside amine yuzuye.
L-Valine ikoreshwa nkibikoresho bya farumasi cyangwa byongera ibiryo.
Ububiko nububiko
Ipaki:
25kg / Ingoma cyangwa nkibisabwa.
Icyitonderwa: Ibigize imiti nubunini birashobora gutezimbere ibyifuzo byabakiriya
Ububiko:
Bika kontineri ifunze cyane ahantu humye, hakonje kandi hahumeka neza. Ubike usibye ibikoresho byibiribwa cyangwa ibikoresho bidahuye.
Kurinda umutekano
Icyitonderwa cyo gufata neza umutekano
Gukorera ahantu hafite umwuka mwiza. Wambare imyenda ikingira. Irinde guhura n'uruhu n'amaso. Irinde gushiraho umukungugu na aerosole. Koresha ibikoresho bidacana. Irinde umuriro uterwa na electrostatike isohoka.
