WebAmino Acids. The naturally occurring amino acids have a common structure. Amino acids, as the name implies, have two functional groups, an amino group (–NH 2) and a carboxyl group (–COOH). These groups are joined to a single (aliphatic) carbon. In organic chemistry, the carbon directly attached to a carboxyl group is the alpha (α) position ... Web9 mrt. 2001 · In presence of nitrogen oxide, no resonance took place due to the interaction between nitrogen and the ionized carboxylic group. Therefore, we favor the species (II) (see Scheme 1).In that case the absorption bands at 1743 and 1379 cm −1 can be observed. But, when the oxidized starch was washed, these absorption bands vanished …
