糖酵解酶 的英文怎麼說
中文拼音 [tángjiàojiě]
糖酵解酶
英文
glycolytic enzyme-
The global regulator csra of e. coli is a specific mrna - binding protein. csra negatively regulates several metabolic pathways that are induced post - exponentially, including glycogen biosynthesis, gluconeogenesis, and glycogen catabolism ; positively controls gene expression within the glycolytic pathway ; and also csra modulates the levels of enzymes that participate directly in pep metabolism
Csra是整體調控網路的調控基因,可負調控指數生長後期誘導的一些代謝途徑,包括糖原的生物合成、糖原的分解代謝、糖異生,而對糖酵解的一些重要基因的表達則執行正調控功能, csra也調控直接參與pep代謝的三個酶的活性水平。The results were as follows : leaching solution by hot water extraction was date in color and had mellow date aroma and the highest fusel oil content but strong bitter taste ; leaching solution by pectinase enzymolysis had the highest reducing sugar content easy for fermentation but excessively high methanol content in fermenting wine ; leaching solution by microwave extraction had the shortest extraction time and fermentation time and the highest ethyl acetate content in wine and the produced wine had special aroma
