Polyacrylic acid is a polyelectrolyte which is soluble in aqueous media at neutral pH, due to the ionization of the pendent carboxyl side chains. Carbopols are polymers of acrylic acid that have been cross-linked with polyalkanyl esters or divinyl glycol. Carbopols readily absorb water, become ...
Carboxylesterse 2EthanolFatty Acid Ethyl Ester SynthaseNon-oxidative MetabolismPalmitic Acid Ethyl EsterAlcoholic beverages are consumed in high volumes globally, and the absorbed ethanol is metabolized by oxidative and non-oxidative pathways. Although the latter pathways are minor, the resulting ...

Post-translational modifications to the carboxyl (C) terminus domain of α-synuclein can play an important role in promoting the pathologic aggregation of α-synuclein. Various cleavages that diminish this highly charged, proline-rich region can result in exposure of hydrophobic, aggregation-prone reg...
The length of this peptide was also examined in labeling experiments with cysteine-reactive probes which indicated that the peptide did not extend to the next carboxyl-containing amino acid residue in the alpha-subunit sequence (Asp804). The site of attachment of DEAC is thus Glu779, an ...
Thus, the cyclic pathway forms an extra molecule of acetyl-CoA, with pyruvate synthase and PEP carboxylase as the carboxylating enzymes. The proposal is based on in vitro transformation of 4-hydroxybutyrate, detection of all enzyme activities, and in vivo-labeling experiments using [1-C]4-...

EDAC is generally utilized as a carboxyl activating agent for amide bonding with primary amines. In addition, it will react with phosphate groups. EDAC has been used in peptide synthesis; crosslinking proteins to nucleic acids; and preparation of immunoconjugates as examples. Typically, EDAC is ...
The C-terminal amino acid of the variant surface glycoprotein from Trypanosoma brucei is glycosylated. For two variant proteins that terminate in an aspartic acid and a serine residue respectively, it was shown that the sugar side chain is linked through ethanolamine to the alpha-carboxy group of...
