Experiments on Wool from Copper-Deficient SheepPart I: Some Physical Measurements on Intact Fibers and Experiments on the Dissolution and Fractionation of Oxidized WoolNational Chemical Research Laboratory, South African Council for Scientific and Industrial Research, Pretoria, South Africa It has been confirmed that wool from copper-deficient sheep has a faster rate of extension in water under constant load than normal; it has been found that this wool has a greater diameter swelling in formic acid and is more easily penetrated by certain large reagent molecules than normal. The dissolution in aqueous buffer solutions of copper-deficient and normal wool after oxidation has been examined and further evidence that the copper-deficient wool is deficient in a sulfur-rich protein fraction, whose absence may he responsible for its physical abnormalities, has been obtained.
