Vanillin is an organic compound with the molecular formula C 8 H 8 O 3. It is a phenolic aldehyde. Its functional groups include aldehyde, hydroxyl, and ether. It is the primary component of the extract of the vanilla bean. Synthetic vanillin is now used more often than natural vanilla extract as a flavoring in foods, beverages, and ...
Glucovanillin, also known as vanilloside, is a chemical compound found in vanilla beans.Chemically, it is a glucoside composed of glucose and vanillin.Glucovanillin is particularly prevalent in green vanilla beans [2] and upon ripening it is hydrolyzed by the action of the enzyme β-glucosidase which releases vanillin, [3] [4] the major contributor to the aroma and flavor of vanilla.
ortho-Vanillin (2-hydroxy-3-methoxybenzaldehyde) is an organic solid present in the extracts and essential oils of many plants. [1] [2] [3] Its functional groups include aldehyde, ether and phenol. ortho-Vanillin, a compound of the formula C 8 H 8 O 3, is distinctly different from its more prevalent isomer, meta-vanillin.
Compounds containing a vanillyl group are called vanilloids, and include vanillin, vanillic acid, capsaicin, vanillylmandelic acid, etc. [1] [2 This organic chemistry article is a stub . You can help Wikipedia by expanding it .
Vanillylamine is produced from vanillin by the enzyme vanillin aminotransferase. [2] It is then converted with 8-methyl-6-nonenoic acid into capsaicin by the enzyme capsaicin synthase . [ 2 ]
Isovanillin is a phenolic aldehyde, an organic compound and isomer of vanillin. [2] It is a selective inhibitor of aldehyde oxidase.It is not a substrate of that enzyme, and is metabolized by aldehyde dehydrogenase into isovanillic acid, which could make it a candidate drug for use in alcohol aversion therapy.

Vanillin–HCl staining (10% vanillin and 90% of a mixture of ethanol and HCl, giving an orange color) can be used to visualize the localisation of tannins in cells. The localization of phlorotannins can be investigated by light microscopy after vanillin–HCl staining. [1] The phlorotannins can be seen this way in physodes in brown algae.
In enzymology, a vanillin synthase (EC 4.1.2.41) is an enzyme that catalyzes the chemical reaction 3-hydroxy-3-(4-hydroxy-3-methoxyphenyl)propanoyl-CoA ⇌ {\displaystyle \rightleftharpoons } vanillin + acetyl-CoA
