REMARKS - The spectrum is dominated by pyrolysis fragments of the sugar moieties (compare with polysaccharide patterns, Group A). The peak at m/z 130 may well represent a dideoxyhexose-minus-H20 unit. No obvious pyrolysis products of the steroid skeleton are observed but note the high peak at m/z 44 (CO2 '?).
