Estimation of total carbonyl content was carried out according to the method outlined by Vuorela et al [3] through two different measurements such as quantification of (a) carbonyls and (b) protein.
IR absorption band from OH groups increased during thermooxidation reactions because there is a disequilibrium in the formation and consumption of hydroperoxides throughout the formation of carbonyls, esters, lactones, and ketones groups[22].
Two of the most commonly measured oxidative protein modifications are protein carbonyls and 3-NT, which are used to assess the cellular status of protein oxidation.

In detail, GO had significantly higher concentrations of ascorbic acid, total free cysteine, [alpha]-tocopherol, and 3-nitrotyrosine and lower concentrations of lycopene, protein carbonyls, and malondialdehyde.
The first seven chapters discuss medicinal chemistry, covering the topics of organometallic enzyme inhibitors, organometallic steroid analogs, chirality in chemotherapeutics, gold complexes, the antimalarial ferroquine, metal carbonyls as prodrugs, and the electronics of nitrosyl and thiol iron complexes.
The solvents, known to be lung irritants, are composed of nicotine and flavouring, and can even transform into carbonyls, or cancer-causing chemicals such as acetaldehyde and formaldehyde.
Those solvents, known as lung irritants, can transform into something even more worrisome: carbonyls. Carbonyls include cancer-causing chemicals, such as formaldehyde, and suspected carcinogens, such as acetaldehyde.
30 January 2014 - A study, conducted at the US University of Louisville (UofL), has discovered that specific volatile organic compounds (VOCs), known as carbonyls and found in exhaled breath, may help the diagnosis of early-stage lung cancer, UofL said.
The experimental results were then evaluated with respect to the sensitivities or reproducibilities across different carbonyls. In the course of this comparative study, preconcentration of CCs by each system was treated by their basic tools such as cartridge derivatization (HPLC-UV) and sorbent tube trapping (GC).
Protein carbonyls are formed through oxidation of proteins by a variety of mechanisms which are the sensitive markers of oxidative injury.
