Acids carboxyl group

Wool has a complex chemical stmcture, composed mainly of a large number of different proteins (87). It is amphoteric in character because of the presence of basic amino and acidic carboxyl groups in the side chains of some of the component amino acids. In an aqueous acidic dyebath, protonation of the amino and carboxyl groups results in a net positive charge on the fiber. [Pg.347]

Amino acids, as their name implies, are difunctional. They contain both a basic amino group and an acidic carboxyl group. [Pg.1016]

The detailed mechanism of this enantioselective transformation remains under investigation.178 It is known that the acidic carboxylic group is crucial, and the cyclization is believed to occur via the enamine derived from the catalyst and the exocyclic ketone. A computational study suggested that the proton transfer occurs through a TS very similar to that described for the proline-catalyzed aldol reaction (see page 132).179... [Pg.139]

The majority of nonsteroidal antiinflammatory agents contain an acidic carboxyl group. A series of experimental agents in this class have been prepared in which the acidic proton is supplied by a highly enolizable proton from a function such as a p-dicarbonyl incorporated into a heterocyclic system. As an example, an acylated, highly oxidized isoquinoline moiety can fulfill this function (see also the benzo-thiazines below). Toward this end, reaction of... [Pg.378]

Thus the monodisperse polystyrene latex stabilized with strong-acid surface groups can be hydrolyzed to form a latex stabilized with the same number of nonionic hydroxyl groups, which in turn can be oxidized to form a latex stabilized with the same number of weak-acid carboxyl groups, thus offering model colloids with identical characteristics except for the type of chemically bound surface groups ---- strong-acid, weak-acid, non-... [Pg.80]

Know the meaning of carboxylic acid, carboxyl group, acyl group, carboxylate anion, acidity or ionization constant, inductive effect. [Pg.190]

Activation of the amino acid carboxyl groups is the only set of clearly reversible reactions catalysed by NRPS. So far these reactions have been studied in the case of ACV synthetases only by the amino acid-dependent ATP-PPi exchange reaction [reaction (11)] ... [Pg.13]
