L-Phenylalanine CAS 63-91-2 bakeng sa Kereiti ea Lijo (FCC / USP)
Tšebeliso:
L-Phenylalanine (Khutsufatso ea Phe) ke amino acid ea bohlokoa ebile ke eona feela mofuta oa phenylalanine o fumanoang liprotheine. Ke e 'ngoe ea li-amino acid tse 18 tse tloaelehileng,' me ke e 'ngoe ea li-amino acid tse hlokahalang' meleng oa motho.
E le tlatsetso ea phepo e nepahetseng, L-phenylalanine e ka bonoa e le sehlopha sa benzyl se emetsoeng ke sehlopha sa methyl sa alanine, kapa sehlopha sa phenyl sebakeng sa hydrogen e sa feleng ea alanine. Boholo 'meleng ke phenylalanine hydroxylase catalysis oxidation ho tyrosine, le synthetic le tyrosine li-neurotransmitters tsa bohlokoa le lihormone, ho nka karolo' meleng metabolism ea tsoekere le mafura metabolism.
L-phenylalanine ke bioactive monko o monate oa amino acid. Ke amino acid e hlokahalang e ke keng ea iketsetsa maiketsetso ke batho le liphoofolo. Ho hlokahala hore motho a je 2.2g L-phenylalanine letsatsi le leng le le leng. E le e 'ngoe ea li-amino acid tse hlokahalang bakeng sa' mele oa motho, e 'nile ea sebelisoa haholo indastering ea meriana le lijo. Ke motsoako oa bohlokoa oa ente ea amino acid. Indastering ea ho lokisa lijo, L-phenylalanine e ka kenyelletsoa lijong tsa bohobe. Le phepo e nepahetseng ea phenylalanine e ka ntlafatsoa le ka amido-carboxylation e nang le glucide.
L-phenylalanine e ka ntlafatsa monko oa lijo le ho boloka li-amino acid tse hlokahalang. Indastering ea litlhare, L-phenylalanine e sebelisoa e le lipakeng tsa meriana e meng ea li-amino anticancer e kang formylmerphalanum joalo-joalo E sebelisoa hape ho etsa adrenalin, thyroxin le melanin. Kopo e 'ngoe ea bohlokoa ke ho kopanya aspartame le L-aspartic acid.
L - phenylalanine ke sesebelisoa sa mantlha sa lihlahisoa tsa bohlokoa tsa lijo tse tsoekere - Aspartame e tsoekere (Aspartame). Joaloka e 'ngoe ea li-amino acid tsa bohlokoa' meleng, L-phenylalanine e sebelisoa haholo bakeng sa tšelo ea amino acid le lithethefatsi tsa amino acid indastering ea meriana.
