Abstract
1. Preps. I and II of the Partial Group Lipoid (active fragment of Group A human liver group lipoid), which had been described formerly in an article2)rom this institute, were investigated regarding structure.
2. The sole ethanolamine molecule in Prep. II or one of the two ethanolamine molecules in Prep. I appears to be joined through its NH2-group with a carboxyl belonging to the amino acid grouping in which glycine has been found to bear its NH2-group in a free state.
3. The polysaccharide was found conjugated with the NH2-group of one of the glutamyl rests in the polypeptide N-glycosidically.
4. Arrangement of the amino acids as well as that of the mono-saccharides was discussed.
The expenses of this work were defrayed by a grant from the Education Department through the Grant Committee for Scientific Researches. H. Masamune.
