The aldehyde or keto group can come into contact with the hydroxyl group of the same molecule, and then a cyclic derivative is obtained from the linear chain (for sugars with n > 4). Cyclization of monosaccharides can occur in two ways. If the hydroxyl group at the fourth carbon atom ...
To visualize PG, cells were grown in an optimized amount of either NAM derivatives1–3. After incubation (0.2% (w/v) of NAM derivative, see Methods andSupplementary Figs 1a and 2), a subsequent Copper (I)-catalysed azide-alkyne cycloaddition, also known as a ‘click’ reaction46, was ap...
are secreted by certain strains of bacteria as slimes. The structure of an individual dextran varies with the strain of microorganism. Dextrans can be used as plasma expanders (substitutes for wholeblood) in cases of severe shock. In addition, a dextran derivative compound is employed medically ...
Starting from the corresponding galactal derivative 11b and following the same route, several galacto-triazole-type compounds 10h−10l were obtained. All the compounds were isolated and fully characterized by their 1H NMR, 13C NMR, and HRMS. The position of alkyl substitution was verified ...
The classical β-oxidation scheme for the breakdown of fatty acids whereby two-carbon units are successively removed is a repetitive process involving four successive reactions. After the initial activation to form a CoA derivative, there is (1) a dehydrogenation, (2) a hydration, (3) a second...
Cisplatin - CPL (cis-diaminodichloroplatin), a platinum derivative, belongs to the group of alkylating medicines. The mechanism of action of alkylating agents is based on damaging the biological activity of the deoxyribonucleic acid, DNA, through the formation of crosslinks between adjacent DNA ...
Inactivation of the pykA gene in strain PB12.SA22 generated the derivative PB12.SA41 (aroL-, aroK-, pykA- strain expressing aroGfbr, tktA, aroB and aroE genes from two different plasmids) (Table 3, Figure 1). Cultures of this strain showed no-significant differences (P < 0.05) in μ...
Stretchable unidirectional liquid-transporting membrane with antibacterial and biocompatible features based on chitosan derivative and composite nanofibers Liling Li, Yongling Mai, Yuanfeng Wang, Shiguo Chen Article 118703 select article Simultaneous adsorption for cationic and anionic dyes using chitosan/electros...
In fact, the change in a weight-loss experiment is extremely far from the total change embodied in free energy values, and the change that is measured (technically, the partial derivative of the energy with respect to reaction) is not path-independent and is notably influenced by the activity...
(g) Percentage of metabolic activity of Jurkat T cells incubated with WT-G3 (positive control), NL-G3, or NL-TT-G3 for 4h.N=4, mean±s.d., n.s. is no significant differences, ****p<0.0001, ANOVA with Tukey’s post hoc; (h) IL-2 produced by Jurkat T cells after...
