    Notes: [Auszug] ACCORDING to the generally accepted view, papain is an enzyme which converts proteins (true ovalbumin ex-cepted) into peptones, and is without effect on the latter. Hydrolytic power towards peptones and true ovalbumin is only acquired after treatment with certain reagents (‘activators’), ...

    Notes: [Auszug] WORKING with latex of Carica papaya, we were able by different methods (dialysis, precipitation, etc.) to separate the natural activator from the enzyme system. When solutions containing the activator were added to a latex preparation ('centrifugate') which split up gelatin, but not ...

    Notes: [Auszug] ON passing a stream of carbon dioxide through strongly cooled, pure α-amino acid esters or their solutions (for example, in ether) with certain precautions, new crystalline products have been obtained. After careful purification the products give analytical data which correspond to the formulæ ...
