Isicelo
I-L-pyroglutamic acid inomsebenzi onamandla wokuthambisa kunye nokungena okuqinileyo kwesikhumba. Njengesongezo esinesondlo kakhulu kwaye sifunxeka ngokulula, sinokulawula ulusu kwaye sisebenze njengento yokuthambisa.
I-L-pyroglutamic acid iphinda ithintele umsebenzi we-tyrosine oxidase, ukwenzela ukuba kuthintelwe ukubekwa kwezinto "ze-melanoid" esikhumbeni kwaye zenze mhlophe ulusu. Iyakwazi ukuthambisa i-cutin kwaye inokusetyenziswa kwizinto zokuthambisa iinzipho.
I-L-pyroglutamic acid inokwenza i-derivatives kunye nezinye izinto eziphilayo. Ineziphumo ezikhethekileyo kumsebenzi ongaphezulu, ukungafihli kunye nokuqaqamba. Isenokusetyenziswa njenge-surfactant kwisicoci; I-reagent ye-Chemical yesisombululo se-racemic amine; Iziphakathi ze-Organic;Aphakathi kwezonyango, izongezo zomzimba.
Ukongama
1. Ngokuqhelekileyo sinezinga letoni kwisitokhwe, kwaye sinokuhambisa izinto ngokukhawuleza emva kokufumana umyalelo.
2. Umgangatho ophezulu kunye nexabiso elikhuphisanayo linokubonelelwa.
3. Ingxelo yohlalutyo lomgangatho (COA) yebhetshi yokuthunyelwa iya kubonelelwa phambi kokuthunyelwa.
4. Ikhweshine yomthengisi kunye namaxwebhu obugcisa anokubonelelwa ukuba kucelwe emva kokudibana nesixa esithile.
5. Inkonzo enkulu emva kokuthengisa okanye isiqinisekiso : Nawuphi na umbuzo wakho ungasonjululwa ngokukhawuleza.
6. Ukuthumela iimveliso ezikhuphisanayo kunye nokuzithumela kumazwe angaphandle ngobuninzi kakhulu ngonyaka.
