1898 Jrnl. Chem. Soc. 74 i. 612 The substances..are called protones; these are, by the prolonged action of pancreatic juice, partially broken up into hexones (lysine, histidine, arginine).
1916 A. P. Mathews Physiol. Chem. iv. 136 It has been suggested by Taylor that the protamine, salmin, may be made up of these tri-peptides, or protones, united as follows.
1928 A. T. Cameron Textbk. Biochem. viii. 115 According to Kossel protamines are hydrolysed first into protones which are compounds containing two radicals of arginine..united with one of alanine, or serine, or proline, or valine.
