Simple structure of a cell
WebbAbstract. An attempt has been made to describe the vibrational spectrum of a vitreous material in terms of a simple model based on the unit cell of the crystal. The model has been adapted to include broad distributions of intertetrahedral angles and configurations which are salient features of the structures of silicate glasses. WebbAll amino acids have the same basic structure, shown in Figure 2.1. At the center of each amino acid is a carbon called the. α carbon. and attached to it are four groups – a hydrogen, a carboxylic acid group, an amine group, and an R-group, sometimes referred to as a variable group or side chain. The α carbon, carboxylic acid, and amino ...
