If the chromic acid oxidation is performed with stoichiometric oxidant in the presence of diethyl ether as co-solvent (a method introduced by H.C. Brown), the epimerization of l-menthone to d-isomenthone is largely avoided.
Apple cider vinegar isn't likely to be effective for weight loss. Proponents of the apple cider vinegar diet claim that drinking a small amount of apple cider vinegar before meals or taking an apple cider vinegar supplement helps curb appetite and burn fat. However, there's little scientific support for these claims.
Apple cider vinegar accelerates the body's ability to break down and derive nutrients from fats and protein efficiently and quickly from the digestive system, which means a faster metabolism and more vitality, says Ellison. Both apple cider vinegar and raw apples contain the fiber pectin. There is evidence to suggest that fibers like pectin can increase a personâs sense of fullness after they eat it, which lowers their desire to overeat or compulsively snack.
