| الوصف: | Gelatin has been interacted with benzenesulphonyl chloride and with other sulphonyl chlorides to give sulphonyl-gelatin derivatives. With dichloro-s-triazines, gelatin afforded crosslinked products or monofunctionally substituted soluble products according to the reactivity of the dichloro-s-triazine selected and the reaction conditions used; some of the monofunctionally substituted soluble products were reactive towards amines, including gelatin. The properties of the modified gelatins are recorded. Introduction of a sufficient number of hydrophobic groups into gelatin and other soluble proteins conferred diminished solubility in the region of the iso-ionic point of the derivative, bringing about the separation of a distinct protein-rich phase (coacervate) from aqueous solution when the pH was adjusted to that region. Some uses of these derivatives are indicated. |
