    Notes: [Auszug] The pneumococcal product differs markedly, however, from N-acetylhyalobiuronic acid, the repeating unit of hyaluronate3 and of the oligosaccharide fractions obtained on digestion with testicular hyaluronidase2 as demonstrated in Table 1. The values indicate that the bacterial product is a ...

    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] 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 ...
