L-Phenylalanine CAS 63-91-2 fun Iwọn Ounje (FCC / USP)
Lilo:
L-Phenylalanine (Abbreviated Phe) jẹ amino acid pataki ati pe ọna kan ti phenylalanine nikan ti o wa ninu awọn ọlọjẹ. O jẹ ọkan ninu awọn amino acids 18 wọpọ, ati ọkan ninu mẹjọ pataki amino acids ni ara eniyan.
Gẹgẹbi afikun ijẹẹmu , L-phenylalanine ni a le wo bi ẹgbẹ benzyl ti o rọpo fun ẹgbẹ methyl ti alanine, tabi ẹgbẹ phenyl kan ni ipo hydrogen ebute ti alanine. Pupọ ninu ara nipasẹ ifoyina phenylalanine hydroxylase catalysis sinu tyrosine, ati sintetiki pẹlu tyrosine awọn neurotransmitters pataki ati awọn homonu, lati kopa ninu iṣelọpọ ara ti gaari ati iṣelọpọ ti ọra.
L-phenylalanine jẹ amino acid oorun oorun bioactive. O jẹ amino acid pataki eyiti ko le ṣe adapọ ti ara ẹni nipasẹ eniyan ati ẹranko. O ṣe pataki fun eniyan lati jẹun 2.2g L-phenylalanine ni gbogbo ọjọ. Gẹgẹbi ọkan ninu awọn amino acids mẹjọ pataki fun ara eniyan, o ti lo ni lilo pupọ ni ile iṣoogun ati ile-iṣẹ afikun ounjẹ. O jẹ eroja pataki ti abẹrẹ amino acid. Ninu ile-iṣẹ iṣelọpọ ounjẹ, L-phenylalanine ni a le ṣafikun sinu awọn ounjẹ akara. Ati pe ounjẹ ti phenylalanine le ni ilọsiwaju ati nipasẹ amido-carboxylation pẹlu glucide.
L-phenylalanine le mu oorun oorun awọn ounjẹ dara sii ki o tọju dọgbadọgba ti awọn amino acids pataki. Ninu ile-iṣẹ iṣoogun, a lo L-phenylalanine bi agbedemeji ti diẹ ninu awọn oogun oogun amino bi formylmerphalanum ati bẹbẹ lọ O tun lo lati ṣe adrenalin, thyroxin ati melanin. Ohun elo pataki miiran ni lati ṣapọpọ aspartame pẹlu L-aspartic acid.
L - phenylalanine ni akọkọ aise ohun elo ti awọn pataki ounje aropo - sweetener Aspartame (Aspartame). Gẹgẹbi ọkan ninu awọn amino acids pataki ninu ara, L-phenylalanine jẹ lilo akọkọ fun gbigbe amino acid ati awọn oogun amino acid ni ile-iṣẹ iṣoogun.
