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.
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 .
A number of vanilloids, most notably capsaicin, bind to the transient receptor potential vanilloid type 1 (TRPV1) receptor, an ion channel which naturally responds to noxious stimuli such as high temperatures and acidic pH. [1]
Based on mRNA expression of TRPV2 in mice, it is also speculated that it is expressed in arterial muscle cells, which can then be influenced by blood pressure; though it was evident that TRPV2 expression was localized in the intracellular area, some growth factors localized it to the plasma cell membrane.

VMA is found in the urine, along with other catecholamine metabolites, including homovanillic acid (HVA), metanephrine, and normetanephrine.In timed urine tests the quantity excreted (usually per 24 hours) is assessed along with creatinine clearance, and the quantity of cortisols, catecholamines, and metanephrines excreted is also measured.
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.
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 ]
