STUDIES ON RABBIT FIBRES

DISCUSSIONS ON THE CARROTTING REACTIONS (PART 1) (PART 2)

Abstract

When rabbit fibre is carroted by the mixture of Hg (NO₃)₂, HNO₃ and NaNO₂, the following correlations may be considered between the amino acid residues and the amounts of weight increase; 1) The increase of cystine is largest 2) Those of tyrosine, tryptophane, lysine, hydroxylysine and arginine are only larger. 3) Those of phenylalanine, histidine serine and threonine are more or less shown. 4) Those of glycine, aranine, proline, valine, leucine, metionine, aspartic acid and glutamic acid are not shown.
The above expectations were tested with the various fibres whose chemical composition was well known i.e. nylon, bombyx mori, antheraea yamamai, wool and Angora rabbit fibre.
