Notes:
Charlesby's equation connecting degree of crosslinking with polymer solubility will adequately explain the decreasing solubility of the urea-bisulfite-soluble protein fraction of wool after the wool has been pre-treated in alkaline solutions. It has been shown that lanthionine thio-ether linkages are probably sufficiently stable crosslinks in the ureabisulfite solutions to account for the lower solubility of alkali-treated wool. They are formed from cystine residues during the alkali treatment. The activation energy of the reaction of cystine residues with hydroxyl ions is 24.4 kcal./mole.
