carboxyl

In these figures, lower precision in the carboxyl end-group concentration measurements is reflected by the greater degree of scatter in these data than in the amine end-group concentration data (Schaffer et al., 2003a; Zheng et l., 2005).

Each amino acid includes a central carbon atom and each of the following functional groups: hydrogen, amino, and carboxyl. Each student should prepare the index cards in Figure 2.

In the example described here, an RNase A enzyme is converted into a zymogen by adding to the enzyme a bridge of amino acids linking the amino and carboxyl termini of the enzyme.

The coat layer comprises a copolymerized polyester having carboxyl group terminals and Tg in the range of 70 to 80[degrees] C., and is formed in an amount ranging from 0.01 to 0.1 g/[m.sup.2] on the base film surface.

To determine the source of the carboxyl group, Zhang et al.

In that area the intensity of the carboxyl peak with the increase of ageing period can be seen, which is the result of the oxidation ageing processes.

An amino acid is an amphoteric organic acid containing both a basic amino group (N[H.sub.2]) and an acidic carboxyl group (COOH).

Addition of a jelling agent such as hydroxypropyl methlycellulose, carboxyl methylcellulose, chitosan, etc., to the cement liquid can improve the washout resistance of the cement paste before hardening occurs, allowing CPC to harden in standing water (11).

Called CHIP (carboxyl terminus of Hsc70-interacting protein), this molecule decides the fate of malformed proteins in heart muscles, says Cam Patterson of the University of North Carolina at Chapel Hill.

The biologically active portion of the molecule is its amidated carboxyl terminus.

The peak intensity at 957 [cm.sup.-1], assigned to the O--H vibrations in carboxyl groups, a potential product of chain scission of PLA, was chosen to calculate the carboxyl index for each film [30, 31].
