性质描述: 含一分子结晶水的乳清酸(C5H4N2O4·H2O,[50887-69-9])为白色针状结晶。熔点345-346℃(分解)。在100ml水中通溶解0.18g,100ml沸水中能溶解13g,极微溶于醇及有机溶剂,不溶于醚。无臭,味酸。
生产方法: 由草酸二乙酯经与乙酸缩合、与尿素环合得到5-乙氧羰基甲叉乙内酰脲,再经扩环、酸析而得乳清酸。
用途: 乳清酸是一种营养药,也称维生素B13。该品与5-氨基咪唑-4-羧酰胺在90℃成盐,则得到氨咪酰胺乳清酸盐(C9H10N6O5·2H2O,[2574-78-9])。这两种药物都是保肝药。

应用

乳清酸(OA)是从头嘧啶生物合成的中间体,可用于研究乳清酸磷酸核糖基转移酶(OPRT)的特异性和动力学,其催化从 5′-磷酸-α-d-核糖 1′-二磷酸(PRPP)到乳清酸(OA)的可逆磷酸核糖转移,形成焦磷酸盐和乳清酸 5′-单磷酸(OMP)。乳清酸用作通过产氨棒杆菌(ATCC 6872)或酿酒酵母等微生物潜在的商业生物生产尿苷 5′-单磷酸(UMP)的原料。乳清酸可用于研究 AMPK/SREBP-1 依赖性细胞信号传导途径,以及研究诱导肝脏脂肪生成的转录调节机制。

应用
Orotic acid is an intermediate in de novo pyrimidine biosynthesis that may be used to study the specificity and kinetics of orotate phosphoribosyltransferase (OPRT) which catalyzes the reversible phosphoribosyl transfer from 5?-phospho-α-d-ribose 1?-diphosphate (PRPP) to orotic acid (OA), forming pyrophosphate and orotidine 5?-monophosphate (OMP). It is used as a starting material for the potential commercial bioproduction of uridine 5?-monophosphate (UMP) by microbes such as Corynebacterium ammoniagenes (ATCC 6872) or Saccharomyces cerevisiae. It may be used to study the AMPK/SREBP-1 dependent cell signaling pathway and transcription regulation mechanisms that induce hepatic lipogenesis.

备注
Stable under recommended storage conditions. Incompatible with oxidizing agents.
