The main work is as follows : ( 1 ) We chose angiotensin converting enzyme ( ACE ) extracted from lung and Aspergillus niger genus lipase to hydrolyse the substrate of hippuryl-histidine-leucine ( HHL ) and tributyrin substrate glycerol ester respectively .

主要工作如下：1.以猪肺血管紧张素转化酶（ACE）水解底物马尿酰-组氨酸-亮氨酸，黑曲霉属脂肪酶水解底物 三 丁酸甘油酯作为研究对象。

Effects of Tributyrin on Leukemia Cell K562 in Vitro

三 丁酸 甘油 酯对K562白血病细胞的体外作用

Next we also probed the molecular mechanism of the effect of natural short-chain fatty acid glyceride-tributyrin on gastric cancer .

其次，作者还探讨了天然短链脂肪酸 甘油三酯 tributyrin 对胃癌 细胞作用的分子机制。

The hydrolysis of tributyrin was tracked by TLC and a strain named T6 which can produce lipase with non special catalysis was obtained . It is identified as Proteus vulgaris by the identification method of configuration physiology biochemistry molecular biology .

利用薄层层析法跟踪脂肪酶水解 甘油三酯 过程，根据 产物 判断脂肪酶催化 位置 特异性，得到一株催化 位置非特异性脂肪酶产生菌T6，经形态，生理生化和分子生物学鉴定该菌株为Proteus vulgaris。

Tributyrin with methanol in the transesterification model reactions showed high catalytic activity 98.03 % conversion rate ; 97.11 % fatty acid methyl ester yield rate ; 99.08 % selectivity rate .

在 三 丁酸 甘油 酯与甲醇的酯交换模型反应中表现出较高的催化活性，转化率达到98.03%；脂肪酸甲酯的产率达到97.11%；选择性达到99.08%。
