Acetovanillone
Acetovanillone, also known as 4-hydroxy-3-methoxyacetophenone or acetoguaiacon, is a member of the class of compounds known as alkyl-phenylketones. Alkyl-phenylketones are aromatic compounds containing a ketone substituted by one alkyl group, and a phenyl group. Acetovanillone is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Acetovanillone is a faint, sweet, and vanillin tasting compound found in corn and garden onion, which makes acetovanillone a potential biomarker for the consumption of these food products. Acetovanillone may be a unique S.cerevisiae (yeast) metabolite.

Sulcatone
Sulcatone, also known as methylheptenone or fema 2707, belongs to the class of organic compounds known as ketones. These are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Sulcatone is a very hydrophobic methylketone, practically insoluble in water, and relatively neutral. It exists as a clear, colorless liquid. Sulcatone can be found in all eukaryotes, ranging from yeast to plants to humans. Sulcatone has a musty, apple green-bean, and pear-like taste. and a citrus-like lemongrass odor. It is a volatile oil component of citronella oil, lemon-grass oil and palmarosa oil. Sulcatone is naturally found in bay leaf, blackberry fruit, sour cherries, cloves, ginger and lavender. In insects and animals, it has a role as an alarm or attractant pheromone. In fact, sulcatone is one of a number of mosquito attractants, especially for those species such as Aedes aegypti with the odor receptor gene Or4 (PMID:25391959 ). Sulcatone is secreted by humans in their sweat and is a compound frequently found in human body odors (but in few other mammals). Sulcoatone is used as a pheromone by ferrets, european badgers, red foxes, treefrogs, bedbugs, wasps and butterflies. Sulcatone is one of several ketones found in Cannabis sativa (PMID:6991645 ). Sulcatone, also known as 6-methylhept-5-en-2-one, is a member of the class of compounds known as ketones. Ketones are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, sulcatone is considered to be an oxygenated hydrocarbon lipid molecule. Sulcatone is slightly soluble (in water) and an extremely weak acidic compound (based on its pKa). Sulcatone is an apple, bitter, and citrus tasting compound and can be found in a number of food items such as oil palm, winter savory, european plum, and swamp cabbage, which makes sulcatone a potential biomarker for the consumption of these food products. Sulcatone can be found primarily in feces and saliva. Sulcatone exists in all eukaryotes, ranging from yeast to humans. Sulcatone is an endogenous metabolite. Sulcatone is an endogenous metabolite.

3,5-octadien-2-one
3,5-Octadien-2-one belongs to the class of organic compounds known as enones. Enones are compounds containing the enone functional group, with the structure RC(=O)CR. An enone, also called an α, β-unsaturated carbonyl, is a type of organic compound consisting of an alkene conjugated to a ketone. 3,5-octadien-2-one exists in multiple cis or trans isomers. The trans-trans or (3E, 5E) form is most biologically relevant. 3,5-octadien-2-one is a clear, yellowy Liquid that is weakly water soluble (1.6 g/L). 3,5-octadien-2-one has a fruity, green, grassy odor. 3,5-octadien-2-one has been detected, but not quantified in, asparagus, oysters and cauliflowers. This could make 3,5-octadien-2-one a potential biomarker for the consumption of these foods. Flavouring compound [Flavornet]
