Abstract
When egg-yolk lecithin was digested with pancreas extract or commercial pancreatin, a powerful haemolytic substance was formed as the intermediate product.
This substance was isolated in pure crystalline state, and was proved to be lysolecithin. It was identical in every respect with lysolecithin formed from lecithin by the action of snake venom.
The author expresses his sincere thanks to Prof. U. Suzuki for his kind guidance throughout this work.
