Many kinds of enols are known. [1] Keto–enol tautomerism refers to a chemical equilibrium between a "keto" form (a carbonyl, named for the common ketone case) and an enol. The interconversion of the two forms involves the transfer of an alpha hydrogen atom and the reorganisation of bonding electrons. The keto and enol forms are tautomers of ...
In pharmaceutical sciences, drug interactions occur when a drug's mechanism of action is affected by the concomitant administration of substances such as foods, beverages, or other drugs. A popular example of drug–food interaction is the effect of grapefruit on the metabolism of drugs .
[2] [83] The European Food Safety Authority established upper limits for some polyphenol-containing supplements and additives, such as green tea extract or curcumin. [89] [90] For most polyphenols found in the diet, an adverse effect beyond nutrient-drug interactions is unlikely. [2]
Dr. McGowan adds a few more: "Fatty meats, high-fat processed foods, cheese-laden pizza and, frankly, most traditional fast foods." That said, experts generally don't recommend completely avoiding ...

At a basic level, blood sugar is balanced by eating a whole-foods diet primarily focused on lean protein, vegetables, and complex carbs, since these foods provide the most reliable and stable ...
The equilibrium constant is 6 × 10 −7 at room temperature, thus that the relative amount of the enol form in a sample of acetaldehyde is very small. [27] At room temperature, acetaldehyde (CH 3 CH=O) is more stable than vinyl alcohol (CH 2 =CHOH) by 42.7 kJ/mol: [28] Overall the keto-enol tautomerization occurs slowly but is catalyzed by acids.
As an enol, phloroglucinol in principle exists in equilibrium with keto tautomers. Evidence for this equilibrium is provided by the formation of the oxime: C 6 H 3 (OH) 3 + 3 NH 2 OH → (CH 2) 3 (C=NOH) 3 + 3 H 2 O. But it behaves also like a benzenetriol as the three hydroxyl groups can be methylated to give 1,3,5-trimethoxybenzene. [4]
