Ascorbic Acid | 50-81-7
IiNkcazo zeeMveliso
I-Ascorbic Acid yikristale emhlophe okanye etyheli kancinane okanye umgubo, i-acid.mp190℃-192℃ encinci, inyibilika ngokulula emanzini, inyibilika kancinane etywaleni kwaye inyibilika ngokungakhululekanga kwi-ether nakwiklorofomu kunye nesinye isinyibilikisi sezinto eziphilayo. Kwimeko eqinileyo izinzile emoyeni. Isisombululo sayo samanzi siguqulwa ngokulula xa sidibana nomoya.
Ukusetyenziswa: Kwishishini lamachiza, lingasetyenziselwa ukunyanga i-scurvy kunye nezifo ezahlukahlukeneyo ezithintekayo kunye nezingapheliyo, zisebenza ngokungabikho kwe-VC.
Kwishishini lokutya, inokusebenzisa zombini njengezongezo zesondlo, i-VC eyongezelelweyo ekulungisweni kokutya, kwaye ikwayi-Antioxidants elungileyo ekugcinweni kokutya, isetyenziswa kakhulu kwimveliso yenyama, iimveliso zomgubo ovundisiweyo, ibhiya, iziselo zeti, incindi yeziqhamo, iziqhamo ezinkonkxiweyo, ezinkonkxiweyo. inyama njalo njalo; ekwasetyenziswa ngokuqhelekileyo kwizinto zokuthambisa, izongezo zokutya kunye nezinye iindawo zoshishino.
