Studien über die Albuminoide mit besonderer Berücksichtigung des Spongin und der Keratine

Abstract

THIS little book does not treat, as its title might lead some to suppose, of the albuminous substances in general, but of that limited group of them to which the term albuminoid is usually restricted by physiologists. This group includes spongin, cornein, gor-gonine, onuphine, conchiolin, spirographin, and silk, which are products (mainly skeletal in function) of the invertebrate world; and collagen, reticulin, elastin, and the keratins, which are found among the vertebrata. One notes in this list the absence of chitin among the invertebrate products, the reason being that this material has now been shown not to be a member of the proteid group at all. Reticulin, also, which is mentioned, and was originally described by Siegfried, does not really exist. Miss Tebb conclusively proved it to be an artifact from collagen, and this view is accepted by Dr. Strauss.
