Fluoride being most electro negative element bears a negative charge and is attracted by positively charged ions like calcium (Ca2+) present in bone and tooth of human body.
In this structure the nitrogen atom bears a positive charge, and the oxygen atom of the acid group bears a negative charge.
Under acidic conditions in the late endosomes, the amine "head" of sphingosine, a putative "pocket factor", bears a positive charge, while α4, α5, α7 of SCARB2 and the late endosomal membrane are negatively charged (Fig. S6A and S6B).
In another mode, since it is well known that the steel surface bears a positive charge in acid solution [24], it is difficult for the protonated inhibitors to approach the positively charged mild steel surface (H3O+/metal interface) due to electrostatic repulsion.
Comparison with earlier results obtained for isonicotinic acid and its methyl ester shows that the dehydration rate constant is at least two orders of magnitude larger when the pyridine nitrogen bears a plus charge, and that the rate constant is at least 100 times smaller for the demethanolation than for the dehydration.
The carboxyl group bears a negative charge, and therefore it is the major functional group in the adsorption of cationic dyes.
Biosorption of both dyes on both biosorbents follow the Langmuir adsorption isotherm model at the ambient pH, at which the breadfruit surface bears a negative charge.
CS bears a negative charge owing to the presence of –COO− and −OSO3− groups.
Carbocation is an organic species which has an electron deficient carbon which bears a positive charge.
This means that whether a carbon center which bears an electron pair has affinity for a proton or alternatively for a carbon center that bears a positive charge.
The carboxyl terminus bears a positively charged di-lysine or arginine motif (GKKKY in yeast; Figure 1B) required for retrieval of Rer1p from the intermediate compartment/cis-Golgi to the ER [ 14].
