3-Methyl-2-butenal

β,β-Dimethylacrylic aldehyde

C5H8O (84.0575)


3-Methyl-2-butenal, also known as senecialdehyde or 3,3-dimethylacrolein, belongs to the class of organic compounds known as enals. These are alpha,beta-unsaturated aldehydes of the general formula RC=C-CH=O in which the aldehydic C=O function is conjugated to a C=C triple bond at the alpha,beta position. 3-methyl-2-butenal has been detected, but not quantified, in several different foods, such as common oregano, beechnuts, oval-leaf huckleberries, tea leaf willows, and red rice. This could make 3-methyl-2-butenal a potential biomarker for the consumption of these foods. 3-Methyl-2-butenal is a derivative of acrolein that is an alpha, beta-unsaturated carbonyl metabolite. It can be formed endogenously during lipid peroxidation or after oxidative stress, and is considered to play an important role in human carcinogenesis. The endogenously formed acroleins are a constant source of DNA damage, can lead to mutation, and can also induce tumours in humans (PMID:8319634). 3-Methyl-2-butenal, which is an unsaturated aldehyde bearing substitution at the alkene terminus, is a poor inactivator of the enzymes protein tyrosine phosphatases (PTPs). The inactivation of PTPs can yield profound biological consequences arising from the disruption of cellular signalling pathways (PMID:17655273). Present in blackberry, grape brandy, cocoa, currants, baked potato, tea, costmary and white bread. Flavouring ingredient

   

Cyclopentanone

3-Acetyl-6-methyl-pyran-2,4(3H)-dione

C5H8O (84.0575)


Cyclopentanone 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. Cyclopentanone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Thus, cyclopentanone is considered to be an oxygenated hydrocarbon lipid molecule. Cyclopentanone is a cyclic ketone, structurally similar to cyclopentane, consisting of a five-membered ring containing a ketone functional group. Cyclopentanone is a colorless liquid organic compound with a peppermint-like odor. Cyclopentanone is found in various foods, including potato and tomato, and cooked foods, e.g. butter, meats, coffee, roasted peanut. Cyclopentanone is also used as a flavouring ingredient.

Thiophene is a maillard product. At room temperature, thiophene is a colorless liquid with a mildly pleasant odor reminiscent of benzene, with which thiophene shares some similarities. The high reactivity of thiophene toward sulfonation is the basis for the separation of thiophene from benzene, which are difficult to separate by distillation due to their similar boiling points (4 °C difference at ambient pressure). Like benzene, thiophene forms an azeotrope with water. Not only is thiophene reactive toward electrophiles, it is also readily lithiated with butyl lithium to give 2-lithiothiophene, which is a precursor to a variety of derivatives, including dithienyl Maillard product
