Abstract

This report is to observe the amino acid composition at silk fibroins among varieties by using paper chromatography method and to study how they may concern with the genetical problem and the biochemical synthesis of the fibroin in silkgland. The results reached are as follows: 1. The amino acid composition of silk fibroin among varieties were observed as similar with each other on the paper chromatogram pictures. 2. In spite of the results of the amino acid composition analysis was similar with other workers results, there was some difference among varieties in numerical analysis. 3. The amino acid composition was considered to concern somewhat with the genetic problem of silkworm. 4. Some nutritive amino acids are considered to related with the worm growth more than the silk fibroin. 5. The paper chromatography of this report showed an unknown amino acid which was not found before in specific species silk fibroin and it is imagined as Hydroxyproline in view of other worker’s graphy result. 6. The biochemical synthesis mechanism of silk fibroin in the silk gland, neither Stepwise process nor Template, could stand with the results of this paper satisfactory one side.
