carboxyl group

Such type of covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amino group of another.

In this investigation, dimethylolpropionic acid (DMPA) is included in the PU structure, and its carboxyl group is ionized to improve the hydrophilicity of poly(IPA)-grafted PU.

In this way, it can adjust the distance between the aromatic ring and carboxyl group [1-3].

These glutamate residues, though, cannot perform their functions unless a carboxyl group is added to them.

The CA molecule consists primarily of three groups: anthraquinone chromophore, a glucopyranose ring attached by a glycosidic linkage, and a carboxyl group (COOH).

The carboxyl group density on the PAAc-g-PDMS surface was measured by a colorimetric method using toluidine blue O staining [13].

The researchers synthesized gold nanoparticles whose surfaces were modified with various functional groups: a positively-charged amino group (-NH2), a negatively-charged carboxyl group (-COOH) or a neutral hydroxyl group (-OH).

This volume presents information on the synthetically useful protective groups in chemical reactions, focusing on major functional groups: the hydroxyl group, phenols and catechols, the carbonyl group, the carboxyl group, the thiol group, the amino group, the alkyne-CH, and the phosphate group.

et al., enhancement in ionic conductivity with increasing salt concentration can be associated to the increase in the number of mobile charge carriers and the interaction between NH4+ ion with carboxyl group bring to high dispersion of H+ that increases the conductivity of the CMC-NH4SCN SBE system [14].
