3-Methyl-2-butenal

β,β-Dimethylacrylic aldehyde

C5H8O (84.0575118)


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 (84.0575118)


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. Found in various foods, including potato and tomato, and cooked foods, e.g. butter, meats, coffee, roasted peanut. Flavouring ingredient

It exists as a clear, colorless oil with a boiling point of 68-70 oC. 1-Penten-3-one is a very hydrophobic molecule, practically insoluble in water, but soluble in most organic solvents. 1-Penten-3-one has a spicy, pungent, peppery odor that is also described as being mustard-like, garlic-like or onion-like, This compound also has a peppery, garlic-like, allium-like, mustard-like or onion-like taste. 1-Penten-3-one has been found in the volatile components of human feces (PMID: 21386183) and saliva (PMID: 24421258). Outside of the human body, 1-Penten-3-one has been detected, but not quantified in, several different foods, such as banana fruit, beef, butter, chives, clams, fish, grapes, grapefruit juice, kiwi fruit, milk, oranges, peaches, potatoes, soybeans, strawberries, black tea and tomatoes. Present in banana, orange peel oil, grapefruit juice, wine grape, peach, fish oil, chicken fat, black tea, soybean, lovage leaf, endive, oyster, clam and cooked beef. 1-Penten-3-one is found in many foods, some of which are asian pear, mango, peppermint, and hard wheat.

   

Methyl propenyl ketone

Methyl propenyl ketone is a very hydrophobic molecule, practically insoluble in water, and relatively neutral. Methyl propenyl ketone, with regard to humans, has been found to be associated with several diseases such as nonalcoholic fatty liver disease and ulcerative colitis. Methyl propenyl ketone has also been linked to the inborn metabolic disorder celiac disease. Methyl propenyl ketone is occasionally found as a volatile component of normal human biofluids. It is found as a volatile in the hawthorn fruit upon ripening, and also is part of the scent components of the urine of some animals. Methyl propenyl ketone is a volatile organic compound.
