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.
When you give it some thought, it makes good sense that drinking apple cider vinegar before meals would help with weight loss. Apples are a good source of pectin, and including pectin in your diet can make you feel fuller and more satisfied.Since apple cider vinegar contains the same amount of pectin as apples (one apple has about 1.5 grams pectin), it can suppress your appetite in a similar way.pples are a great source of potassium, and likewise, apple cider vinegar, taken on a regular basis, will contribute the potassium you need to help balance the sodium in your diet. In fact, try replacing salt in your diet with apple cider vinegar.
