3,3-Dimethyl-1-butanol


3,3-Dimethyl-1-butanol is a structural analog of choline.

Effects

DMB inhibits microbial trimethylamine formation in mice and in human feces, thereby reducing plasma trimethylamine N-oxide levels after choline or carnitine supplementation. It consequently inhibited choline-enhanced endogenous macrophage foam cell formation and atherosclerotic lesion development in mice without alterations in circulating cholesterol levels.
While mice placed on a choline supplemented diet showed an increase in the proportions of the bacterial taxon Clostridiales in the gut, DMB induced a decrease in the proportions of this taxon.
Mice showed no evidence of toxicity to chronic DMB exposure.

Occurrence

DMB is found in some balsamic vinegars, red wines, and some cold-pressed extra virgin olive oils and grape seed oils.
