It breaks glucose down into molecules called pyruvate that are fed to the mitochondria for processing 此分解过程产生了一定的能量，但并不多。
Studies on the heterogeneous asymmetric hydrogenation of ethyl pyruvate and acetophenone catalyzed by supported rhodium 负载型铑催化剂催化潜手性羰基化合物的多相不对称氢化反应的研究
It is also formed from glyceraldehydes 3 - phosphate in glycolysis , with the release of atp , after which it may be converted to phosphoenol pyruvate 也可以由糖酵解过程中的甘油醛3 ?磷酸形成，伴随有atp的释放，然后可能转化为磷酸烯醇式丙酮酸。
In bacterial , many enzymes compete for intracellular pep , especially the phosphotransferase system which is responsible for glucose transport in e . coli . this system uses pep as a phosphate donor and converts it to pyruvate , which is less likely to recycle back to pep Pep和e4p是dahp合成的限制性底物，在大肠杆菌中， pep又是许多酶的竞争性底物，特别是负责葡萄糖转运的糖磷酸基转运系统。
Ppsa and tkta are the key genes in central metabolism of aromatic amino acids biosynthesis . ppsa encoding phosphoenolpyrucate synthetase a ( ppsa ) which catalyzes pyruvate into pep ; tkta encoding transketolase a which plays a major role in erythrose - 4 - phosphate ( e4p ) production of pentose pathway Ppsa基因编码磷酸烯醇式丙酮酸合成酶a ( ppsa ) ，该酶催化丙酮酸合成磷酸烯醇式丙酮酸； tkta基因编码转酮酶a ，该酶在磷酸戊糖途径中生成4 -磷酸赤藓糖起主要作用。
The genes encoding pyruvate decarboxylase ( pdc ) and alcohol dehydrogenase ii ( adh ii ) were amplified from total dna of zymomonas mobilis by pcr . the genes of adhb andpdc were inserted into expression vector pse380 and then transformed into e . coli dh5a . the recombinant strains were induced to express adh ii and pdc with iptg 本论文以zymomonasmobilisdna为模板， pcr扩增zymomonasmobilis中的乙醇脱氢酶基因( adhb )和丙酮酸脱羧酶基因( pdc ) ，分别构建表达质粒pse - adhb和pse - pdc并在大肠杆菌dh5中表达。
