Abstract
Earlier work at this Bureau has shown that wool that has been reduced with thioglycolic acid and then alkylated with ethyl bromide is attacked by pepsin in such a way that the scale material remains intact, whereas the interior of the fiber is completely dissolved. The composition of the scale material so obtained has now been studied. It is essentially protein; it contains the same amino acids as the whole wool, but in different proportions:[long dash]the whole wool used in this work contained 12.2% of cystine, 8.6 of arginine, 6.1 of tyrosine, and 9.5 of serine, whereas the scale material contained 20.3, 4.8, 3.3, and 11.2%, respectively.This publication has 7 references indexed in Scilit:
