The chitin is modified to impart the structure required by the functions of each particular tissue, via crystalHzation, deacetylation, cross-finking to other biopolymers (Fig. 1), and, in certain cases, quinone tanning. The resulting complex structures are capable of exceptional performances [15]. 

Early biochemical studies supported the hypothesis that the HRl and the HR2 peptides would interact to form a helical structure (Chen et al. 1995 Lu et al. 1995). This hypothesis was strengthened when X-ray structures were resolved for co-crystals of HRl and HR2 peptides (Chan et al. 1997 Tan et al. 1997 Weissenhom et al. 1997). The results showed that in the six-helix bundle, three HRl domains were packed tightly together in the center of the bundle, with the HR2 domains bound in an antiparallel manner in grooves formed along the HRl core. 

Leather is the material made from animal skin by the process of tanning, which entails chemically altering the composition of the skin so as to make it durable and resistant to decay. Leather is therefore not a protein but a protein derivative. Although the tanning process alters the composition of skin, leather retains the fibrous structure and utilitarian functionality that make skin suitable for multifarious applications. Shelter, clothing, and decorative objects made from leather are, unlike skin or hide, stable to physical, chemical, and biological decay under dry or wet conditions (O Flaherty et al. 1965 ...
