    Notes: [Auszug] THE word ‘cellulose’ possesses two connotations: in a technical sense it denotes products obtained by certain processes from vegetable material; in a chemical sense it is commonly used for a linear high-molecular polysaccharide composed solely of glucose residues linked by α 1-4 glucosidic ...

    Notes: [Auszug] Rubber-like Properties of Hair Keratin IT follows from the classical work of Joule 1 that the restoring force of stretched rubber is due to thermal motion. Meyer, y. Susich and Valk 2 showed for rubber at 100–300) per cent extension that the force at constant extension is proportional to the ...

    Notes: [Auszug] IN a series of communications in NATURE, Dr. D. M. Wrinch1 has put forward a new hypothesis on the structure of certain proteins—the ‘yclol-theory’. According to this, peptide chains should be capable of uniting to form two- and three-dimensional nets, three peptide residues ...

    Notes: [Auszug] Fibrous proteins have been classified by Astbury1 into two groups, the keratin–myosin–fibrinogen group and the collagen group. The first group exhibits ‘long-range’ elasticity, which is attributed to attractive forces tending to establish a special folding of the protein chains in the contracted ...

    Notes: [Auszug] IF cellulose is precipitated from solution or liberated from its compounds with sodium hydroxide, the space lattice (a = 8.14 A., b = 10.3 A., c = 9.14 A., (β = 62°) differs from that of native cellulose (a = 8.35 A., b = 10.3 A., c = 7.9 A., (β = 84°). In this form it is known as hydrate ...
