Hair Proteins and Crosslink Structures

1 Chemical structure and crosslink formation of protein component 

The HS protein is a globular protein, rich with Cys (i proximately llOOmmol/g) and with molecular weight about 20kDa, that forms a 

Protein types Rod Domains N-, C-terminal Total M.W. X10- Molecalar weight 

For a hair, when it is 2 1.25, the value of fgjf is independent of I and is 0.11. Also, for the hair where the SS bond is decreased by 14% by a reduction reaction, the fgjf value is 0.08 for k 1.55 and the hair shows gel-like entropy elasticity [54]. The fgjf value of natural rubber is 0.18-0.25 [55]. In the diluted system using this special mixed solvent, because even a fiber rich with SS bonds such as hair shows almost ideal rubber elasticity at a large deformation, quantitative analysis of the crosslinks is done using this phenomenon.
