However, whether such reactions, as carbonyl stress has a primary role or a secondary effect of apoptotic tissue damage in diabetes is under vigorous debate.

According to carbonyl stress theory of aging, carbonyl-amine reaction as a common reaction of free radical oxidation and non-enzymatic glycosylation is an inevitable and irreversible core process during the slow aging procedure caused by oxidation and glycosylation.

To study various deleterious alterations of malondialdehyde(MDA) on erythrocytes and the inhibitive effect of glutathione(GSH) on the MDA-related carbonyl stress.

In this thesis, from the viewpoint of environment, we discussed the carbonyl stress a.

Study on Simulation of Vibrant Frequency of Carbonyl;

Two isoxazole intermediates containing 1,2,3triazolyl and carbonyl,which can also be used as intermediates for synthesis of new heterocyclic compounds,have been synthesized.

0,the amount of oxidation element Ⅰ 4%,the temperature 85 ℃ and the time 4 h;the optimum conditions to obtain the maximal carbonyl content was: pH=5.

The conditions/reagents for protecting carbonyl groups as acetals, thioacetals and oxothioacetals as well as the corresponding deprotection processes published during the period of 2000～2006 are briefly surveyed.

This article narrates the transformation of carbonyl group in optically active epoxy ketones under different reagents and enumerates some synthetic applications of this kind of transformation.

The chemical reductants fail to reduce carbonyl group under ambient conditions.

The mass spectral fragmentation of long chain carboxide compounds was discussed and calculation of molecular formula was proposed in the paper.

It bas been discovered that the carboxylic ester rare earth salt is superior to the organotin in antidehydrochlorination, and inferior to the organotin in antioxidation through following the tracks of carboxide group and conjugated double bond with the help of infrared spectroscopy and ultraviolet-visible spectroscopy.
