Two amino acid sequences from potentially helical fragments of low-sulphur proteins from α-keratin have been analysed computationally and periods 9.4 and 28 residues long noted in the axial disposition of charged residues. Ionic interactions between

Wool treated with N-ethylmaleimicle (NEMI) to decrease the sulfhydryl content by 70% supercontracts much more slowly than untreated wool at 98.5° C. in 6 M LiBr at pH 6, whereas in 4 M LiBr/l N HCl the contraction rates of treated and untreated fibe

A comparatively rapid paper chromatographic method has been developed for estimating lanthionine without prior oxidation to lanthionine S-oxide. The method is applicable to hydrolyzates of most proteins and estimates as little as 5 μmoles/gm with go

Animal fibers were reduced to varying degrees with solutions of thiols and alkylated with methyl iodide or ethylene dibromide. The stress-strain curves of S-methylated Lincoln wool fibers showed the following characteristics. The stresses at the end

Iodination of wool fibers in ethanol or n-propanol accelerates the first stage and retards the second stage of supercontraction. Iodination in aqueous KI3 has little effect on the rate of the first stage but retards the second stage of supercontracti

Observations of changes in crimp of wool fibers during supercontraction in aqueous solutions have led to a means of modifying the crimp of fibers from a single fleece. Felting studies on such modified fibers have shown that straightening of the wool

Treatment of wool with 40% (wt./wt.) HNO3 at 0-30° C. for periods up to 18 hr. causes a decrease in sulfhydryl, disulfide, and tyrosine contents and an increase in free amino groups. An equivalent concentration of HCl under similar conditions causes

Various solvent systems have been investigated for obtaining maximum alkylation of cysteine residues in reduced wool to dimethylene-S,S'-dicysteine residue. These and related amino acid residues were determined in wool hydrolyzates by means of an aut

In a series of trials in four carbonizing mills, the addition of a nonionic surface active agent to the sulfuric acid bowl resulted, in each experiment, in an increased yield of car bonized wool and, on spinning, increased yarn strength. In a similar
