The carbon chain on the D ring of cholesterol is degraded by functionalizations with carboxyl groups and sequential decarboxylation reactions.
42.
When the carboxyl group of the C-terminus is replaced with a methylamide, further elongation of the peptide chain is prevented.
43.
The first mechanism is a reaction between perchloromethyl mercaptan and biological functional groups such as hydroxyl, sulfhydryl, amino and carboxyl groups.
44.
It was suggested that the modification leads to faster changes in conformation due to the restrictions introduced by the carboxyl group.
45.
The covalent chemical bonds are formed when the carboxyl group of one amino acid reacts with the amine group of another.
46.
It can still bind by chelating to the metal atoms on the surface, probably through either the cyanate or carboxyl groups.
47.
Ionized carboxyl groups ( RCO 2 " ) are formed by hydrolysis of the collagen by the action of hydroxide.
48.
Isopeptide bonds can occur between the side chain amine of lysine and the side chain carboxyl groups of either glutamate or aspartate.
49.
The deprotonation of the carboxyl group causes the lone pair of electrons to move down making carbon dioxide and separating from oxalosuccinate.
50.
Next, a glycine is incorporated fueled by ATP hydrolysis and the carboxyl group forms an amine bond to the NH 2 previously introduced.
