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.
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. [3]
Synthetic essence consists of a solution of synthetic vanillin in ethanol. The chemical compound vanillin (4-hydroxy-3-methoxybenzaldehyde) is a major contributor to the characteristic flavor and aroma of real vanilla and is the main flavor component of cured vanilla beans. [40] Vanillin was first isolated from vanilla pods by Gobley in 1858. [41]
Vanillylmandelic acid (VMA) is a chemical intermediate in the synthesis of artificial vanilla flavorings [1] and is an end-stage metabolite of the catecholamines (epinephrine, and norepinephrine). It is produced via intermediary metabolites.
Vanillic acid (4-hydroxy-3-methoxybenzoic acid) is a dihydroxybenzoic acid derivative used as a flavoring agent. It is an oxidized form of vanillin. It is also an intermediate in the production of vanillin from ferulic acid. [2] [3]
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, para-vanillin.
The nitrile obtained reacts with a hydroxamic acid chloride to give a 3,5-disubstituted 1,2,4-oxadiazole as a further intermediate. Intermediate in the opicapon synthesis. With hydrazides, the aldehyde 5-nitrovanillin forms hydrazones that can be cyclized with Chloramine-T to give substituted 1,3,4-oxadiazoles. [10]
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
