The occurrence of FA and carbonyl compounds
(acetaldehyde, acrolein, EC, formaldehyde and furfural) was studied in this research with the objective of verifying, for the first time, the risk of exposure to these compounds through consumption of sparkling wines.
Schiff bases 1-17 were synthesized by condensation of 1-aminoanthracene-9,10-dione with variety of aromatic and aliphatic carbonyl compounds
using reported catalytic method (Fareed et al., 2013).
However, the isomers in low molecular carbonyl compounds
such as acetone/propionaldehyde and butanone/butyraldehyde were difficult to analyze by the APCI-MS/MS due to the same molecular mass.
constitute the major aromatic substances in yoghurt [13, 14].
Application of the Swern oxidation to the manipulation of highly reactive carbonyl compounds
, Journal of organic chemistry, 50(12): 2198-2200.
A class of carbonyl compounds
is called [alpha],[beta]-unsaturated carbonyls, also referred to as electrophilic carbonyls.
The highly significant difference (pless than 0.01) was recorded for the content of phenols, carbonyl compounds
, cyanides, dissolved oxygen, biological oxygen demand, total soluble salts, total dissolved salts, nitrates and sulphates, whereas, the concentration of magnesium, potassium and oil and grease differed significantly (pless than 0.05) with respect to the sampling points on average basis.
MGO and glyoxal (GO) are reactive carbonyl compounds
that are by-products of auto-oxidation of glucose, lipid peroxidation and protein glycation, a process where protein and glucose interact, interfering with the function of protein in the body.
This reaction takes place between carbonyl compounds
and active methylene compounds for the production of carbon-carbon bond, and it is considered as one of the most important methods to produce functionalized alkenes.
(2006) demonstrated that volatile 3MH and 4MMP could be formed from other carbonyl compounds
are known to instigate harmful chemical reactions) and nitrogen produced by glycation.
From the generals of structure and bonding and functional groups, stereochemistry,and reactivity to the specifics of alkynes, alkenes, benzenes, carbonyl compounds
et al., it's all here.
Previous work has explained that the majority of whisky's odor contribution comes from carbonyl compounds
. Yet it is interesting to note that, while carbonyl compounds
are the most prevalent odor components of the compounds present, they have the smallest combined mass, with alcohol being a major component as whisky is legally required to be a minimum of 40% alcohol by volume.
"Although the data are preliminary, we found that patients with an elevation of three or four cancer-specific carbonyl compounds
was predictive of lung cancer in 95% of patients with a pulmonary nodule or mass," Dr.
