Now, it is seen that polar groups dominate the molecular structure, resulting from hydroxyl groups from the two serine and threonine fragments in addition to the peptide bonds themselves. Only weak dispersive interactions will be contributed by glycine fragments (CH2 groups).

Glycines site antagonists which have been shown to be effective in analgesic models can be divided into different chemical classes although so far any high affinity effector molecule of the glycineB site bears more or less the structural motif of glycine within its molecular structure, as can be observed in the first example, kynurenic acid.

Some molecular structures are shown below. These molecules are all amino acids, the constituents of proteins. Look at the number of carbon atoms in each molecule and the way they are bonded together. Even within this small class of molecules there s great variety—glycine and alanine have only two or three carbon atoms phenylalanine has nine. ...

The monomeric building blocks of the biopolymers, called proteins, are the a-amino acids. The simplest amino acid is glycine, which has the molecular structure shown in Figure 23.18. An amino acid, as indicated by the name, must contain an amine group (—NH2) and a carboxylic acid group ( —COOH). In a-amino acids, the two groups are bonded to the same carbon atom. In acidic aqueous solution, the amine group is protonated to form —NHj in basic solution, the...
