產(chǎn)品介紹

丙氨酸是人體中一種很小的非必需氨基酸,丙氨酸是蛋白質(zhì)結(jié)構(gòu)中最廣泛應(yīng)用的一種,它參與了色氨酸和維生素B6的代謝。丙氨酸是肌肉和中樞神經(jīng)系統(tǒng)的重要能量來源,增強(qiáng)免疫系統(tǒng),幫助糖和有機(jī)酸的代謝,并在動(dòng)物身上顯示降低膽固醇的作用。DL-丙氨酸,一種化學(xué)品,用作制造維生素B6的原料,醫(yī)學(xué)微生物和生物化學(xué)氨基酸代謝用。有甜味,味覺值0.06%.。200℃升華,264~269℃分解。并隨加熱速度而不同。由水-乙醇液重結(jié)晶者為斜方晶體系,由水重結(jié)晶者為針狀結(jié)晶或結(jié)晶性粉末。10%水溶液的PH值5.5-7.0,約于295-300℃熔化并分解,化學(xué)性能穩(wěn)定,遇亞硝酸可轉(zhuǎn)變?yōu)長(zhǎng)-乳酸。無旋光性。氨基酸代謝和生化研究,有機(jī)微量分析測(cè)定氮和氨基氮的標(biāo)準(zhǔn)樣品,肝功能試驗(yàn)中測(cè)定谷一丙轉(zhuǎn)氨酶活力 。
