Scholarcy highlights

  • In Part 1 of this series, the complete amino acid composition of a 16-hr hydrolysate of Merino wool of 64's quality was presented
  • The results previously reported for Merino wool of 64's quality are included for comparison
  • A comparison of the amino acid composition of the three types of wool is rendered easier by reference to the block diagram of Figure 1, where the percentage by weight of each amino acid is presented
  • In all cases the nitrogen content has been almost quantitatively accounted for, making it unlikely that any further unknown amino acids are present in these hydrolysates. iI> The two samples of Merino wool differ by more than 10 per cent. in their aspartic acid, cystine, glycine, phenylalanine, serine, and threonine contents, while the Corriedale 56's hydrolysate differed
  • It must be emphasized that except for the cystine, methionine, and tryptophan results, the analyses reported are replicate determinations on the same wool hydrolysate, and do not include variations from sample to sample
  • In view of the variation between the wools reported in the present paper, work at present in progress aims to assess the extent of the variation from site to site on the sheep, between individual sheep of the same strain, and between different strains of Merino sheep
  • The overall pattern of the amino acid composition of the three wools is similar small variations between the wools are observed with some of the amino acids
