Isolation and characterization of 1-O-alpha-2-acetamido-2-deoxy-D-galactopyranosyl-myo-inositol from pregnancy urine.

ABSTRACT

A new neutral glycoside of myo-inositol was isolated from the pregnancy urine of a single donor. Its structure was investigated by 1H-NMR spectroscopy and mass spectroscopy. It was identified as 1-O-alpha-2-acetamido-2-deoxy-D-galactopyranosyl-myo-inositol. No such structure or sequence has previously been reported in either myo-inositol or glucose glycosides.
