malate n.【化學】蘋果酸,蘋果酸鹽(或酯)。

malathion

The tested isozymes included esterase ( est ) 、 superoxide dismutase ( sod ) 、 malate . dehydrogenase ( mdh ) 、 malic enzyme ( me ) 、 glutamate dehydrogenase ( gdh ) 、 peroxidase ( per ) and alcohol dehydrogenase ( adh ) . there were obvious differences between the normal strain and its degenerative strain in est 、 mdh 、 me 、 sod . the zymotype were the same in the other isozymes . the results were not only used to test the degenerative strain at young stage , but also as the theoretical base to study the genetic mechanism of the degenerative strain 而其余四種酶在正常菌株和退化菌株中酶譜一致。本研究不僅可以作為菌株退化早期鑒別的手段之一,而且為進一步研究菌種退化遺傳機理提供了蛋白質水平上的一些理論依據。

First , three isozymic systems ( lactate dehydrogenase ( ldh ) , esteraes ( est ) , malate dehydrogenase ( mdh ) ) extracted from threepopulations of mandarinfishes were detected by discontinuous vertical plate polyacrylamide gel electrophoresis ( page ) . several loci were tested but none polymorphic locus was detected in qiupu river population . the results showed that : ldh can be used as biochemical markers to identify these three populations of mandarinfishes 首先,本試驗采用聚丙烯酰胺凝膠電泳( page )對我省三個水域鱖魚群體3種同工酶( ldh 、 est 、 mdh )的不同基因座位進行了檢測,結果表明: ldh同工酶可以作為區分秋浦河鱖魚、長江鱖魚兩個群體與萬佛湖鱖魚群體的生化遺傳標記;其次,運用rapd技術分析了三群體鱖魚的基因組dna的多態性。

We present a preliminary study on the zymograms of esterase ( est ) , lactate dehydrogenase ( ldh ) , malate dehydrogenase ( mdh ) from four groups of microtus fortis by vertical discontinous polyacrylamide gel electrophoresis method . the number , mobility and dye intensity of the enzyme band were analyzed 采用垂直板不連續聚丙烯酰胺凝膠電泳法對四類東方田鼠的酯酶( est ) 、蘋果酸脫氫酶( mdh )和乳酸脫氫酶( ldh )進行了初步研究。
