Proteins,tal tissues, pliant and stiff, of animals and plants. The precise complement of amino acids or sugars and their sequential order along the chain ultimately controls the mechanical properties of the material which they form. These chemicals and the materials they form are the subject of this and the next three chapters.

Basic Theory of Elasticity and Viscoelasticity, to the forces which hold the constituent atoms or molecules together. This occurs in simple crystalline (including polymeric crystalline) and ceramic materials, and such materials are typically very rigid. Or it can feed the energy into large changes in shape (the main mechanism in rubber and other

Biological Ceramics, relatively light and, with chitin as the fibre, can make a tough skeleton. Moreover its mechanical properties can be very closely tailored to its use by varying the order and complement of amino acids in the protein matrix, so that the insect cuticle can be adapted to perform many functions, from m
