chemical compound groups

Organosulfur compounds can be classified into a vast range of compound groups based on the number of sulfur containing compounds. The different ... Several other organosulfur compounds such as disulfides and dibenzothiophene are used as catalysts and reactants in several chemical reactions.

This indicates that the bacteria are consuming the oil. The research team wanted to decode which parts of the oil were being consumed and how. Oil is a complex material, consisting of hundreds of chemical compounds, but the scientists focused their efforts on two compound groups that the bacteria may be responding to.

The method performs a polarity-based class-separation of the oxidized TAGs, providing information on groups such as the hydroxyperoxy-, hydroxyl-, epoxy-, or oxo (ketone or aldehyde)-TAGs, or TAGs with combinations of these chemical functionalities. This method remains challenging, primarily because ...

GC-VUV spectral data is inherently three dimensional (time, absorbance, wavelength) and specific to compound chemical structure. .... K.A. Schug, M. Garbalena, P. Walsh, Rapid Analysis and Time Interval Deconvolution for Comprehensive Fuel Compound Group Classification and Speciation Using Gas ...

Additional quantification of produced volatile compounds showed that production of all compound groups in R. cyanocarpum exceeded production in R. .... With the exception of available potassium, all physico-chemical soil properties showed significant differences between the three sites (Table 4).

Notably, compound 40 did not show significant cytotoxicity toward 32D cells or HSCs, nor did it augment leukemia cell proliferation. Taken together, our newly discovered p18SMIs represent novel chemical agents for murine and human HSCs ex vivo expansion and also can be used as valuable chemical ...

Hugs increase the level of the powerful feel-good hormone oxytocin and cause a drop in stress chemicals such as cortisol. Keep your gums healthy Columbia University researchers say they have “the most direct evidence yet” that getting rid of gum disease protects against heart disease by reducing ...

A compound group known as catechins may provide some protection. Catechins have an antioxidant anti-inflammatory ... Some chemicals in coffee include chlorogenic acid, thus cutting stroke risks by lowering the chances of developing type 2 diabetes. Further research could clarify how the interaction ...

"We would like to see further research to understand the underlying biological mechanisms for these findings." It's unclear how green tea affects stroke risks. A compound group known as catechins may provide some protection, as they have an antioxidant anti-inflammatory effect. Some chemicals in coffee ...

Chartier looks for attractions (his term) between chemical compounds in food and wine; Hanni emphasizes how all these ingredients get funneled ... One of the aromatic compound groups noted for beef is the terpenes, which add herb and spice notes. .... Are these isolated chemicals really magic bullets?
