The guanidine group of the amino acid arginine is ubiquitous in Nature In its protonated state, several resonance forms that delocalize the cationic charge of the guanidinium cation over the entire functional group contribute to the high basicity of guanidine (pK aH = 136 in water) 1 The Hbonding ability ofGuanidine is one of the most versatile functional groups in chemistry;Abstract Here we applied a novel method1a to predict pKa values of the guanidine functional group, which is a notoriously difficult This method, which was

Guanidine is not expected to undergo hydrolysis in the environment due to the lack of functional groups that hydrolyze under environmental conditions(2) Guanidine does not contain chromophores that absorb at wavelengths >290 nm and therefore is not expected to be susceptible to direct photolysis by sunlight(2)Turner Construction Company Aug 13 Jun 151 year 11 months Dallas/Fort Worth Area Project Hall Arts Center Downtown Dallas ($72 million)Lipoplexes of DNA and siRNA 68 The polar (cationic) headgroup can be an amine (primary, secondary, tertiary, and even quaternary eg, imidazolium 9) or guanidine functional group Guanidines, the most basic functional group in biological chemistry, are positively charged at physiological pH 74 as they have pKa = 125 10 Guanidines
Guanidine and Functional group See more » Guanidine nitrate Guanidine nitrate is the chemical compound with the formula NO3 New!!Arginine R (Arg) Arginine, an essential amino acid, has a positively charged guanidino group Arginine is well designed to bind the phosphate anion, and is often found in the active centers of proteins that bind phosphorylated substrates As a cation, arginine, as well as lysine, plays a role in maintaining the overall charge balance of a proteinConsidered to have acidic character At pH=1, Pepcid's guanidine group will be ionized in the stomach (pKa=105;
The use of the guanidine functional group to connect monosaccharide units in glycooligomers is particularly attractive with regard to molecular recognition processes Like thioureas and ureas, guanidines can also form bidentate hydrogen bonds In addition, because of their positively charged character, guanidines can exert strong electrostaticIn one embodiment, the bicyclic guanidine compound may be chosen from a compound of Formulas (2)(9) or a combination of two or more thereof One or more different guanidinecontaining compounds with a guanidine functional group as part of a fused ring system may be used as the catalyst material in the ring opening polymerization process The multidendate binding capabilities of the guanidine functional group A high concentration of guanidines can also assist with translocation across membranes 11, 15–17 thus underlying the fact that polyarginine functions as a cellpenetrating peptide 18–
