Structural analysis of choline phospholipids by fast atom bombardment mass spectrometry and tandem mass spectrometry.
The structures of intact choline phospholipids were determined by positive and negative ion mode fast atom bombardment mass spectrometry, tandem mass spectrometry, and B2/E and B/E constant linked
Characterization of acetylenes and terpenoids isolated from Solidago altissima L.
This study presents the first isolation of (E)-dehydromatricaria lactone from Solidago altissima L. in nature and shows that compounds 1, 2, 3, 4, and 5 exhibited growth inhibitory activity, whereas compound 7 did not exhibit the activity.
Odor Components of Human Breath After the Ingestion of Grated Raw Garlic
The major odor components of finely grated, raw garlic in the air of the human mouth have been studied. Immediately after garlic ingestion, tests of the mouth air of six subjects revealed two major
A novel ceramide trihexoside from the eggs of the sea urchin, Hemicentrotus pulcherrimus.
The finding of melibiosylceramide (Gal alpha 1-6Glc beta 1-1Cer) from the eggs of another sea urchin species and the present finding of the novel ceramide trihexoside suggest that there are a variety of unique sugar structures in sea urnin glycosphingolipids.
Sugar-pendant diamines.
This method has been used to synthesize a library of sugar-pendant diamines including an OH-protected derivative, and an N,N'-diisopropyl-substituted derivative.
The location of double bonds in a cerebroside from edible fungi (mushroom) estimated by B/E linked scan fast atom bombardment mass spectrometry
The structure of a cerebroside isolated from Hypsizigus marmoreus (mushroom, Bunashimeji) was determined to be (4E, 8E)-N-2-hydroxyhexadecanoyl-1-O-β-glucopyranosyl-9-methyl-C18-sphinga-4,8-dienine
