Isicelo
I-L-pyroglutamic acid inomsebenzi oqinile wokuthambisa kanye nokungena okuqinile esikhumbeni. Njengesengezo esinomsoco kakhulu futhi esimunca kalula, singalawula isikhumba futhi sisebenze njengesithambisa.
I-L-pyroglutamic acid iphinde ivimbele ukusebenza kwe-tyrosine oxidase, ukuze ivimbele ukufakwa kwezinto "ze-melanoid" esikhumbeni futhi yenze isikhumba sibe mhlophe. Ingathambisa i-cutin futhi ingasetshenziswa kuzimonyo zezinzipho.
I-L-pyroglutamic acid nayo ingakha ama-derivatives namanye ama-organic compounds. Inemiphumela ekhethekile emsebenzini ongaphezulu, obala nokukhanya. Ingasetshenziswa futhi njenge-surfactant yokuhlanza; I-Chemical reagent yokuxazulula i-racemic amine; I-Organic intermediates;Iziphakathi zezokwelapha, izithasiselo zomzimba.
Ukuphakama
1. Ngokuvamile sinezinga lethani esitokweni, futhi singaletha impahla ngokushesha ngemva kokuthola i-oda.
2. Ikhwalithi ephezulu kanye nentengo yokuncintisana inganikezwa.
3.Umbiko wokuhlaziywa kwekhwalithi (COA) wenqwaba yokuthunyelwa uzonikezwa ngaphambi kokuthunyelwa.
4. Uhlu lwemibuzo yabahlinzeki kanye nemibhalo yezobuchwepheshe inganikezwa uma isicelo emva kokuhlangabezana nenani elithile.
5. Isevisi enhle yangemuva kokuthengisa noma isiqinisekiso : Noma yimuphi umbuzo wakho uzoxazululwa ngokushesha okukhulu.
6. Thumela imikhiqizo encintisanayo futhi uyithumele emazweni angaphandle ngobuningi njalo ngonyaka.
