查询词典 mercapto

The major causes of off-flavour of the cooked rice was due the intractions among rice proteins, lipids and carbohydrates, which result in the production of carbonyl compounds,the increase of caproaldehyde,and the decrease of acetaldehyde and mercapto group as well as the changes in the cell wall structures.

本文结合近几年研究工作及国内外对大米陈化研究的新进展，综合阐述了随大米存放时间的延长，其化学组织特别是大米蛋白质、类脂与淀粉的共同作用，促使羰基化合物的生成、乙醛减少、己醛增加、SH基减少，以及胞壁改变，是造成大米陈化、米饭&陈米臭&的主因。

During the process of sepsis, trace dose of leptin injected peritoneally significantly improves and stabilizes the hepatic and renal functions. The mechanisms may be related with those intestinal enzymes associated with metabolism of free radicals, mercapto group and purine. Indomethacin exerts a similar role as leptin though at much higher dose.

Results are summarized as follows:(1) The absorption property of CdSe nanoparticle colloid under magnetic field was investigated by magnetic circular dichroism measurement, which proved the discrete energy states in CdSe nanoparticles due to size confinement effects.(2) Aggregation of small nanoparticles was usually observed under HRTEM measurements. In order to obtain HRTEM images of well dispersed particles, surfactant molecules were assembled on the surfaces of mercapto acetate stabilized CdSe nanoparticles.
