I-Malic Acid CAS: 6915-15-7 Umthengisi woMvelisi

I-asidi ye-malic, i-HOOCCH(OH).CH2COOH, eyaziwa ngokuba yi-hydroxysuccinic acid, yinto eqinileyo engenambala. Iyanyibilika emanzini nasetywaleni. I-asidi ye-malic ikhona kwiindlela ezimbini ezisebenzayo kunye nomxube we-racemic. Isetyenziswa kwezonyango kwaye ifumaneka kuma-apile nakwezinye iziqhamo. I-isomer yendalo yi-L-form efunyenwe kuma-apile nakwezinye iziqhamo ezininzi kunye nezityalo. I-asidi ye-malic yeyona acid yesithathu incinci ye-alpha hydroxy ngobukhulu beemolekyuli. Nangona isetyenziswa kwiimveliso ezininzi zokuthambisa, ngakumbi ezo zibonisa umxholo we-"asidi yeziqhamo" kwaye ngokubanzi yenzelwe ukulwa nokwaluphala, ngokungafaniyo ne-glycolic kunye ne-lactic acids, iingenelo zayo zolusu azikafundwa ngokubanzi. Abanye abenzi be-formula bakubona kunzima ukusebenza nayo, ngakumbi xa kuthelekiswa nezinye ii-AHA, kwaye inokucaphukisa kancinci. Ayisetyenziswa rhoqo njenge-AHA yodwa kwimveliso. Ifumaneka ngokwendalo kuma-apile. I-asidi ye-malic isetyenziswa kwiifomyula zamayeza njenge-acidulant esetyenziselwa injongo eqhelekileyo. Inencasa encinci ye-apile kwaye isetyenziswa njenge-agent yokunambitha ukufihla incasa ekrakra kunye nokubonelela ngoburhabaxa. I-asidi ye-malic ikwasetyenziswa njengendlela eyahlukileyo endaweni ye-citric acid kwimigubo ekhupha amanzi, ii-mouthwash, kunye neepilisi zokucoca amazinyo.
