of its molecular structure is that the molecule contains two chemically different groups. One is an inorganic-philic group that easily reacts chemically with the surface of inorganic matter; the other is an organic-philic group that can react chemically with synthetic resins or other polymers or ...
For extraction of polar and apolar lipids, mycobacterial cells were suspended in 1:1 ratio of petroleum ether and methanolic saline (10:1) and the mixture was stirred for 2–4 h. Afterward cells were pelleted at 7000 × g and non-aqueous phase containing apolar lipids was ...
Non-saponifiable lipids were extracted two times in petroleum ether, washed with water, dried under nitrogen gas and stored at À 80 °C. For compound calibration, 2 mM solutions in 0.1% formic acid were directly infused into the mass spectrometer. Ergosterol, lanosterol and zymosterol ...
Bis(pinacolato)diboron is insoluble in water but soluble in common organic solvents, including non-polar solvents such as petroleum ether and hexane, and low-polarity solvents such as ether. It is worth mentioning that in the literature, Bis(pinacolato)diboron is often further purified by recrystal...
muricata were extracted, using petroleum ether, ethyl acetate and methanol by a Soxhlet extractor and preliminary phytochemical screening was performed, using standard protocols. In vivo antipediculicidal activity was assessed in backyard poultry and premises and had good drug response at higher ...
The introduction of defined non-polar deletion of various genes (33) confirmed the above results. This analysis identified additional genes that either down-regulate or induce transcription of rpoEP-lacZ. Thus, a ΔarcB mutation led to an increase in transcription, whereas ΔrpoS and Δcrp ...
Chemistry is the branch which deals with the detailed study of matter, its properties, how and why atoms/substanced combine or separate to form other substances. Understand all the basic concepts of Organic, Inorganic, and Physical Chemistry with detaile
The liver X receptor (LXR) is a member of the nuclear receptor family of transcription Search Way of life, presumptions about the world, along with understanding Posted onDecember 7, 2024 Reply Remarkably, characterizations associated with cycled electrodes show almost identical structures and advise...
Non-ionic surfactants aresurfactants that have polar head groups that are not electrically charged(see Fig. 20.18). They usually rely on a functional group able to deprotonate but only to a very low degree. What is degree Ethoxylation?
Non-saponifiables contained trace FFA contamination and polar compounds (migrated between triglyceride and FFA). Fig. 1 Appearance (a), UV spectrum (b), and thin-layer chromatography results (c) of BMSO and its fractions. I, BMSO; II, saponifiables; III, non- saponifiables; IV, bleached...
