The presence of glycolipids on wool fibers has been detected by analyzing the solubilized material when wool is treated with different organic solvents selected to remove internal lipids. One of these has been isolated and identified as a glucosilceramide. These compounds are thought to contribute to the bilayer structure that may be present in the β-layers of the cell membrane complex.

The role of nonkeratinous proteins in the crimp formation of wool fibers by draft and immediate relaxation was investigated. For this purpose, Australian Shropshire wool fibers were treated with formic acid and pronase (proteolytic enzyme) to modify the nonkeratinous proteins. Formic acid is known to remove some of the intercellular cement, one of the nonkeratinous proteins, from the cell membrane complex, while pronase removes all nonkeratinous proteins. Little crimp formation occurred in the wool fibers treated with formic acid and pronase, indicating that the nonkeratinous proteins, especially the intercellular cement of the cell membrane complex, play an important role in the crimp formation of wool fibers by the draft and immediate relaxation process. A similar effect on crimp formation also occurred when the wool fibers were steamed in a relaxed state.

Cell Membrane Complex

The cell membrane complex of wool has been examined by electron microscopy of stained. cross sections after immersion of the wool in formic acid. The cell membrane complex of the cortex is considerably modified by the treatment, but that of the cuticle appears unchanged. Resistant membranes from cuticle cells, cortical cells and wool have been prepared by treatment with performic acid-ammonia. Amino acid analyses show that the resistant membranes from the cuticle contain citrulline but those from cortical cells do not. It is concluded that the cell membrane complex of the cuticle differs from that of the cortex. Because of the high lysine content of the resistant membranes, their resistance to chemical attack, the hydrophobicity of epicuticle and the observation of a small amount of e-(y-glutamyl)lysine, it is postulated that the resistant membranes may contain an appreciable amount of e-(y-glutamyl)lysine cross links.
