The structure and properties of some natural organic compounds, conveniently considered here. It must be remembered that the less common amino acids may be structurally and biologically very important in particular proteins; for example, hydroxyproline and hydroxylysine in the collagens; or they may be essential for certain metabolic processes, such as ornithin

The structure and properties of biopolymers,idal dimensions, and hence their solutions have properties often similar to those of colloidal dispersions. The macromolecules with which we are concerned in this chapter are polymeric materials which occur naturally, and hence are called .. The term . defines a molecular structure built up of repea
