L-Phenylalanine CAS 63-91-2 no ka papa ʻai (FCC / USP)
Hoʻohana:
L-Phenylalanine (Pōkole Phe) kahi amino acid pono a ʻo ia wale nō ke ʻano o ka phenylalanine i loaʻa i nā protein. ʻO ia kekahi o nā 18 mau amino acid maʻamau, a ʻo kekahi o nā walu amino pono ʻino i ke kino o ke kanaka.
Ma ke ʻano he mea kōkua kōkua !, L-phenylalanine hiki ke ʻike ʻia ma ke ʻano he hui benzyl i pani ʻia no ka hui methyl o alanine, a i ʻole kahi hui phenyl ma kahi o kahi hydrogen terminal o alanine. ʻO ka hapanui o ke kino e ka phenylalanine hydroxylase catalysis oxidation i loko o ka tyrosine, a synthetic me nā tyrosine nui neurotransmitters a me nā hormones, e komo i ke kino i ke kō a me ka momona momona.
ʻO L-phenylalanine kahi waikawa amino aika ala. He acid amino pono ia ʻaʻole hiki ke synthesize ʻia e nā kānaka a me nā holoholona. Pono ia i kahi kanaka e lawe iā 2.2g L-phenylalanine i kēlā me kēia lā. Ma ke ʻano he ʻewalu amino acid pono no ke kino o ke kanaka, ua hoʻohana ākea ʻia ia i nā ʻoihana lāʻau lapaʻau a me nā mea hoʻohui meaʻai. He mea waiwai nui ia o ka amino acid injection. I ka ʻoihana hana meaʻai, hiki ke hoʻohui ʻia ka L-phenylalanine i loko o nā meaʻai bakery. A hiki ke hoʻonui ʻia ka meaʻai o ka phenylalanine a e ka amido-carboxylation me ka glucide.
Hiki i ka L-phenylalanine ke hoʻomaikaʻi i nā mea ʻala a mālama i ke kaulike o nā amino acid pono. I ka ʻoihana lāʻau lapaʻau, hoʻohana ʻia ʻo L-phenylalanine ma waena o kekahi lāʻau lapaʻau anticancer amino e like me formylmerphalanum a me nā mea ʻē aʻe. Hoʻohana ʻia ia e hana adrenalin, thyroxin a me melanin. ʻO kekahi noi nui e synthesize i ka aspartame me ka L-aspartic acid.
L - phenylalanine ka mea maka maka o ka mea hoʻohui mea nui - mea ʻono Aspartame (Aspartame). Ma ke ʻano he amino acid pono i loko o ke kino, hoʻohana nui ʻia ka L-phenylalanine no ka transfusion a me ka amino acid i ka ʻoihana lāʻau.
