Ketones, Aldehydes, Acids

Aldehydes: An aldehyde is an organic compound containing a functional group with the structure -CHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain. Because of the instability of aldehydes, most of them exist in the form of derivatives of aldehydes. Aldehydes are the active components of medicinal drugs and have the potential to be used as antioxidants, anti-parkinson drugs and sedative-hypnotic drugs. Ketones: Ketones are carbonyl group containing compounds, having aliphatic non-cyclic, aliphatic cyclic or phenyl constituents on both sides. They are comparatively stable than aldehyde due to hindrance as well as electronic effect and sometimes exist as tautomer with enol, which makes them water soluble. Acids: Compounds with an acidic functional group in their structure e.g. sulphonic, phenolic or carboxylic. Carboxylic acids are more commonly referred to as acids. They are widely distributed in nature in the form of lactic acid, formic acid, butyric acid, propionic acid, citric acid, acidic amino acids, malice acid, fumaric acid and etc. They are potentially used as acidulants, antioxidants, metallic detoxifiers in plants. It can also be used as product stabilizer and food additives.

Furthermore, deletion of either the gene encoding the histidine kinase or the response regulator of the TC system resulted in the loss of the ability to grow on (S)-2-Hydroxysuccinic acid, thus indicating that the cognate TC system regulates and is essential for the expression of ME. Transcriptional analyses shows that expression of maeE is induced in the presence of (S)-2-Hydroxysuccinic acid and repressed by glucose, whereas TC system expression is induced by (S)-2-Hydroxysuccinic acid and is not repressed by glucose.
