Abstract:
The high performance separation and pre-concentration of polar phenols from aqueous matrices is difficult because of the strong interactions between phenols and water molecules. Conjugated microporous polymers (CMPs) are a kind of novel porous organic materials. Polyphenylene core-conjugated microporous polymers (PPc-CMPs) were used as a novel coating material in the solid-phase microextraction of polar phenols in water samples for the first time. The novel PPc-CMPs fibers exhibited good thermal stability (>450 °C), high enrichment factors (519-2372), low limits of detection (0.02-0.05 ng L-1), wide linearity (0.1-1000 ng L-1), and good repeatability (2.5%-8.1%) for polar phenols. The new coating was successfully used in the analysis of phenols in real environmental water samples. PPc-CMPs as a polar solid-phase microextraction coating material was excellent for the rapid and sensitive analysis of phenols at trace levels in the environment.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
Phase II Reactions: Miscellaneous Conjugation Reactions
A key example involves the conjugation of cyanide ions, which impair cellular respiration and alter hemoglobin into non-oxygen-carrying cyanmethemoglobin. To neutralize this threat, a sulfur atom from thiosulphate is transferred to the cyanide ion, catalyzed by the enzyme rhodanese, resulting in an inactive compound called thiocyanate. The production of...

The paradox
Nucleosomes, paradoxically, perform two opposite functions simultaneously. On the one hand, their main responsibility is to protect the delicate DNA strands from physical damage and help achieve a higher compaction ratio. While on the other hand, they must allow polymerase enzymes to access DNA...
