“… lecithins … phospholipids that were inactive or scarcely active per se, such as phosphatidylethanolamine and lysophosphatidylcholine (miristoyl; Iysod 14 ) increased the activating efficiency of lecithins, (b) ApoHBD …-water interface was not essential for HBD activity since a molecular dispersion of diheptanoyl lecithin (diC 7 ) activated apoHBD to a limited extent.”
