ʻO D-2-Aminobutyric Acid (HD-Abu-OH) (CAS: 2623-91-8) kahi isomer o L-Aminobutyric Acid.
Introduction: ʻO D-2-Aminobutyric Acid he amino acid derivative a hiki ke hoʻohana ʻia ma ke ʻano he reagent biochemical.
Hoʻohana: D-2-Aminobutyric Acid he kī waena o nā lāʻau lapaʻau chiral, chiral pesticides a me chiral food additives, a hoʻohana nui ʻia i nā ʻano lāʻau lapaʻau, pesticides a me nā meaʻai.ʻO ka D-2-Aminobutyric Acid he waika α-amino chiral koʻikoʻi.He mea koʻikoʻi kemika a me ka chiral intermediate, a hoʻohana nui ʻia i ka synthesis lāʻau.
ʻO ke ala Synthesis: I kēia manawa, hōʻike ka palapala e pili ana i ka synthesis o D-2-Aminobutyric Acid, e like me ka hoʻohana ʻana i ka methionine i ka hoʻonohonoho d ma ke ʻano he mea maka e synthesize D-2-Aminobutyric Acid ma o ka desulfurization a me nā hana ʻē aʻe.Ammonia hydrolysis reaction method, chemical separation method, etc. ʻO ka mea mua, ua acetylated ka racemic 2-Aminobutyric Acid e loaʻa ai ka N-Acetyl-2-Aminobutyric Acid, a laila hoʻohana ʻia ka amino acylase i unuhi ʻia mai ka puʻupaʻa puaʻa e koho i ka hydrolyze (S). )-configuration N-Acetyl-2-Aminobutyric Acid, ma laila e loaʻa ai ka (S)-2-Aminobutyric Acid, ka mea unhydrolyzed (R)-N-Acetyl -2-Aminobutyric Acid i racemized e kahi ala kūpono e loaʻa ai ka racemic 2-Aminobutyric Acid. , no laila e ʻike ai i kāna hoʻonā kinetic ikaika a hiki i kāna hopena hope loa i ka 71.9%.
Hoʻohana: Hoʻohana ʻia ka D-2-Aminobutyric Acid ma ke ʻano he lāʻau waena
