Abstract
1. The Group B lipoid of hog lung was subjected to alkaline cleavage and then fractioned.
2. The precipitate occurring on hydrolysis proved to mainly consist of tetracosanol-1.
3. The supernatant fluid was acidified and exhausted with ether. Into ether passed an acetone-insoluble group-active fragment and acetonesoluble organic acids palmitic acid and probable unsaturated acids.
4. The scission products that remained thereby in water were found to be aspartic and glutamic acid, glycine, alanine, arginine and inositoland α-glycero-phosphoric acid.
5. Its large part precipitated when the group-active, essentially electrophoretically-homogeneous fragment (Partial Group Lipoid) was hydrolyzed with acid, and the supernatant here proved to contain aspartic and glutamic acid, serine, hexosamine (glucosamine and chondrosamine), ethanolamine, galactose and glycerophosphoric acid in molecular proportions of 1:2:2:2:1:4:5.
