| Description | 4-Hydroxy-3,5-dimethoxybenzaldehyde belongs to the class of organic compounds known as methoxyphenols. Methoxyphenols are compounds containing a methoxy group attached to the benzene ring of a phenol moiety. 4-Hydroxy-3,5-dimethoxybenzaldehyde is a mild, sweet, and plastic tasting compound. 4-Hydroxy-3,5-dimethoxybenzaldehyde is found, on average, in the highest concentration within a few different foods, such as common walnuts (Juglans regia), grape wine, and whisky and in a lower concentration in spirit, vinegar, and rum. 4-Hydroxy-3,5-dimethoxybenzaldehyde has also been detected, but not quantified in, several different foods, such as coconuts (Cocos nucifera), common grapes (Vitis vinifera), corianders (Coriandrum sativum), corns (Zea mays), and garden tomato (var.). This could make 4-hydroxy-3,5-dimethoxybenzaldehyde a potential biomarker for the consumption of these foods. 4-Hydroxy-3,5-dimethoxybenzaldehyde is a secondary metabolite. Secondary metabolites are metabolically or physiologically non-essential metabolites that may serve a role as defense or signalling molecules. In some cases they are simply molecules that arise from the incomplete metabolism of other secondary metabolites. Based on a literature review a small amount of articles have been published on 4-Hydroxy-3,5-dimethoxybenzaldehyde. This compound has been identified in human blood as reported by (PMID: 31557052 ). Syringaldehyde is not a naturally occurring metabolite and is only found in those individuals exposed to this compound or its derivatives. Technically Syringaldehyde is part of the human exposome. The exposome can be defined as the collection of all the exposures of an individual in a lifetime and how those exposures relate to health. An individual's exposure begins before birth and includes insults from environmental and occupational sources. |
