Q.1 Is Phenol acidic or basic? Ans. Phenol is a poor acid. In aqueous solutions within the pH range of 8-12, it is in equilibrium with the phenolate anion C6H5O- (also phenoxide). Phenol is more acidic than aliphatic compounds as it contains an OH group. The phenoxide anion is st...
What is phenol acidic? Phenol isa very weak acidand the position of equilibrium lies well to the left. Phenol can lose a hydrogen ion because the phenoxide ion formed is stabilised to some extent. The negative charge on the oxygen atom is delocalised around the ring. ... That is why phen...
To further examine the development of colon crypts, we found that elongated crypts inFam3D−/−mice were not present at birth but appeared progressively with aging. Goblet cell dysfunction was manifested first as a shift from the production of acidic mucin toward neutral mucin in the colonic e...
Dysregulation in pre-mRNA alternative splicing (AS) is emerging as a hallmark of cancer7. Nearly all multi-exon human genes undergo AS, a tightly regulated process that dramatically expands diversity of the transcriptome and proteome encoded by the genome7,8. As an essential process for removing ...
capable of improving the bonding strength between a rubber and a reinforcing material and giving a reinforced material having improved rigidity without deteriorating the health of worker by reacting a phenol with an oxo compound and a urethane in the presence of an acidic catalyst under specific ...

We show that astrocytes, as judged by glial fibrillary acidic protein (GFAP) expression, never emerge from neuroepithelial cells on embryonic day (E) 11.5 even when STAT3 is activated, in contrast to E14.5 neuroepithelial cells. A CpG dinucleotide within a STAT3 binding element in the GFAP ...
excited luciferin 6′-hydroxyl group is shown to be lower than the rate of emission by the phenol form itself and, consequently, although ground and excited p K values differ considerably (8.5 and 0.5 respectively), blue fluorescence is observed in non-polar and strong acidic aqueous solutions....
Following isolation and culture, live mouse islets were exposed to 100 nM Mtphagy dye (Dojindo Molecular Technologies) for 3 h to assess time-dependent accumulation of mitochondria to acidic organelles by the relative fluorescence intensity of the dye per cell91,92. Islets were then dissociated...
rnf genes are widespread in bacteria and biochemical and genetic data are in line with the hypothesis that they encode a membrane-bound enzyme that oxidizes reduced ferredoxin and reduces NAD and vice versa, coupled to ion transport across the cytoplasmi
