Intengo enhle kakhulu lg lycine a mino a cid Impushana
1. Isingeniso Sokukhiqiza :
I-Glycine (Gly), eyaziwa nangokuthi i-Amino Acid, iyi-AID engabalulekile ye-Amino ngefomula yamakhemikhali C2H5NO2. I-Glycine yi-amino acid ye-endoGenous antioxidant inciphise i-glutathione, evame ukwengezelelwa ngokuxakile lapho umzimba ungaphansi kwengcindezi enkulu futhi kwesinye isikhathi ubizwa ngokuthi yi-amino acid ebalulekile. I-Glycine ingenye yama-amino acid alula kakhulu.
I-Glycine eFomu eliqinile ingumhlophe onsundu ophikisayo we-crystalline powder, amaphunga nangewona anobuthi. Kuyancibilika kalula emanzini futhi kucishe kufakwe infolol noma ether. Inamaqembu asebenzayo kanye ayisisekelo namasisekelo ku-molecule, futhi angaba yi-Iogoned emanzini, nge-hydrophility eqinile. I-Glycine ingathatha amafomu ahlukile ama-molecular ngokulungisa i-acidity kanye ne-alkalinity yesisombululo esinamanzi.

I-Occression:
I-Glycine yi-amino acid elula kunazo zonke phakathi kwamalungu angama-20 ochungechunge lwe-amino acid, eyaziwa nangokuthi i-amibonga acid, okuyi-amino acid engabalulekile emzimbeni womuntu. Ukulungiswa kwe-acidity kanye ne-alkalinity yekhambi lamanzi anamanzi angenza i-glycine ibonise amafomu ahlukile ama-molecular amafomu. Isibopho esiseceleni kwe-glycine yi-athomu le-hydrogen. I-Glycine ayiyona i-isomeric ejikelezayo ngenxa yekhabhoni yayo ye-alpha ne-athomu elilodwa le-hydrogen. Njengoba ibhodi eliseceleni le-glycine lincane kakhulu, lingahlala izikhala amanye ama-amino acid angenawo, ngokwesibonelo, njenge-amino acid ngaphakathi kwe-helix yase-collagen helix. Kuyi-crystal emhlophe noma i-light ophuzi crystalline powder emazingeni okushisa asekamelweni. Inokunambitheka okumnandi okuhlukile, okungase kulinganise ukunambitheka kwe-acid kanye ne-alkaline, imaski umunyupho futhi uthuthukise ubumnandi bobumnandi be-saccharin eyengeziwe ekudleni.
4. Isicelo:
1.DED EMkhakheni Wezemithi, Ukuhlolwa Kwe-Biochemical kanye Synthensis Organic
2. Isetshenziswa njenge-ejenti yokuhlasela, esetshenziselwa ukulungiselela izicubu zamasiko amaphakathi, ithusi, igolide kanye nesiliva
3. I-Glycine isetshenziswa ikakhulukazi njengezengezo zokudla okunempilo kokuphakelwa kwenkukhu.
4. Izithasiselo zokudla okunempilo. Iningi elisetshenziselwa ukunambitha njll.
I-5. Kusetshenziswe njenge-solvent yokususa i-carbon dioxide embonini yomanyolo
