Structural Elucidation of Novel Phosphocholine-containing Glycosylinositol-phosphoceramides in Filamentus Fungi: (2). Spectral Analysis of the Sugar-inositol Portion by 2D-NMR

The sugar-inositol portion of the novel glycosylinositol-phosphoceramides, ZGL1 and ZGL2, from the filamentus fungi, Acremonium sp., were elucidated by a combination of NMR techniques including (1)H-(1)H (COSY and HOHAHA) and (1)H-(13)C (HMQC and HMBC) spectroscopy. Further, examination of the (1)H-(31)P HMQC spectrum showed connectivity of inositol and ceramide through phosphate.
