Pabrik Pasokan High Quality DL-Phenylalanine lan L-Phenylalanine
Deskripsi Produk
Phenylalanine minangka asam amino aromatik sing penting ing manungsa (disedhiyakake saka panganan), Phenylalanine nduweni peran kunci ing biosintesis asam amino liyane lan penting ing struktur lan fungsi akeh protein lan enzim.Phenylalanine diowahi dadi tirosin, digunakake ing biosintesis neurotransmiter dopamin lan norepinefrin.Bentuk L saka Phenylalanine digabungake menyang protein, dene bentuk D minangka obat penghilang rasa sakit.Penyerapan radiasi ultraviolet dening Phenylalanine digunakake kanggo ngitung jumlah protein.
L-phenylalanine minangka L-enantiomer saka phenylalanine.Nduweni peran minangka nutraceutical, mikronutrien, metabolit Escherichia coli, metabolit Saccharomyces cerevisiae, metabolit tanduran, metabolit alga, metabolit tikus, metabolit xenobiotik manungsa lan inhibitor EC 3.1.3.1 (alkaline phosphatase).Iki minangka asam amino kulawarga erythrose 4-phosphate/phosphoenolpyruvate, asam amino proteinogenik, fenilalanin lan asam L-alpha-amino.Iki minangka basa konjugat saka L-phenylalaninium.Iki minangka asam konjugat saka L-phenylalaninate.Iki minangka enantiomer saka D-phenylalanine.Iki minangka tautomer saka zwitterion L-phenylalanine.
