The introduction of negatively charged sulfate groups plays a crucial role in extracellular biomolecular interactions that dictate various cellular processes, including cell adhesion, leukocyte trafficking, hormone activities, and immune responses3,4,5,8. Tyrosine-sulfated proteins (referred hereafter as ...
Microbial functional group activities such as the ability to reduce sulfate and generate sulfide by sulfate reducing bacteria (SRB), oxidize sulfide and reduce nitrate by sulfide oxidizing, nitrate reducing bacteria (soNRB), and nitrate reduction by heterotrophic nitrate reducing bacteria (hNRB) were ...
the source of DIC in deep-sea sediments could be attributed to either anaerobic oxidation of methane or organoclastic sulfate reduction (OSR) [20]. Both processes utilize sulfate as an electron acceptor, convert carbon in methane or other complex organic compounds...
(168.0±0.5 eV) and sulfate(169.5±0.5 eV).The results show that nitrogen present in coal in pyrrolic forms is converted into pyridinic functionalities upon heat treatment and nitrogen oxides disappeared above 900 ℃.The major organic sulfur form in NXL is thiophene and its content is over 50%...
2.4.2Advantages of preparing functional textiles by radiation grafting At present, the main drawback of conventionalfunctional textilepreparation methods is that the combination offunctional materials(or groups) on textiles is insecure, resulting in poor functional durability. The energy ofionizing radiation...
The proportion of positive cells in the RI-, FSK-, cAMP-, and NOG-treated groups was: 30.9 ± 4.5%, 26.6 ± 4.6%, 24.3 ± 4.3%, and 18.0 ± 2.1% (mean ± SEM) respectively (Fig. 2b). The combination of NOG, FSK, and RI (NFR) was more effective ...
Since the polymer has a functional group corresponding to the polymerization initiator and the aforesaid electron-donating groups (functional groups), it can perform a great variety of functions by taking advantage of these functional groups. 展开 ...
b Chemical structures of the lipids used and their composition in the complex lipid bilayer (if present). Enclosed in the box are the lipids used in the homogeneous bilayer systems, covering all three headgroups and varying levels of acyl chain unsaturation. POPC (1-palmitoyl-2-oleoyl-sn-...
The first functional group (i.e., precursor functional group) is a group, which after undergoing a chemical reaction can be converted into a sulfonate, sulfate, carboxylate, phosphonate, or phosphate. In one embodiment, the precursor functional groups may be selected from the following: a hydroxy...
