During pyrolysis, the kerogen macromolecules underwent a series of complex thermal decomposition reactions, featuring chemical bonds (crosslinks) breakage, along with the constant breaking, parting and cyclization of alkyl side chains, the carboxyl group
and ether bond functional groups in the aliphatic hydrocarbons.
The carboxyl group
density on the PAAc-g-PDMS surface was measured by a colorimetric method using toluidine blue O staining .
Ala253 and Ala249 (backbone donor) both expressed interactions with oxygen of hydroxyl group and carboxyl group
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.
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 .
Then we examine this interaction as a function of glycine rotate and then the carboxyl group
10x molar excess 1-ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride (EDC) and N-Hydroxysuccinimide (NHS) were added to activate the carboxyl group
of ELP to facilitate the formation of a peptide bond between ELP and PA (Figure 1).
CCP Composites US LLC has been granted a patent for a thermosetting, crosslinkable resin composition suitable for preparing a gel coat, the composition is comprised of: a polyester acrylic polymer having an average of more than two polymerizable carbon-carbon double bonds in each molecule, the carbon-carbon double bonds in the polyester acrylic polymer being from a reaction product of a saturated polyacid half-ester having an average acid functionality of two or more and an unsaturated epoxide monomer in about chemically equivalent amounts to furnish one epoxy group per carboxyl group
, the saturated polyacid half-ester being the reaction product of one or more polyols having an average of at least two hydroxy
2), with the cinnamic acids having a double bond between the carboxyl group
and the benzene ring.
In this review, the author follows mainly the trail of his studies on four groups of typical enzymes with a catalytic carboxyl group
Free carboxyl group
form electrovalent bonds that provide stickiness.
