1903 Jrnl. Chem. Soc. 84 i. 587 The protamines of fish spermatozoa are possibly formed by the polymerisation or condensation of kyrine or similar decomposition products of the proteids.
1906 Jrnl. Chem. Soc. 90 i. 777 Kyrines, the intermediate decomposition products of proteids by acids.
1916 Jrnl. Chem. Soc. 110 i. 103 The author has examined some kyrines in order to determine whether they differ in toxicity from their parent proteins.
1928 Physiol. Rev. VIII. 408 The close resemb[l]ance of these preparations to each other in properties and composition led him [sc. Siegfried] to suggest the generic name kyrine for them with the implication that they were the kernel, or nucleus, of the molecular structure of the proteins from which they were derived. This view was founded upon the resistance to hydrolysis of the kyrines under the conditions employed in their preparation.
1953 Chem. Abstr. 47 12474 Gelatin was..hydrolyzed with acid by Grassman's method..to kyrine sulfate.
