Metabolite Identification
Common Namexi-2-Ethyl-1-hexanol
Description2-ethyl-1-hexanol, also known as fema 3151, is a member of the class of compounds known as fatty alcohols. Fatty alcohols are aliphatic alcohols consisting of a chain of a least six carbon atoms. Thus, 2-ethyl-1-hexanol is considered to be a fatty alcohol lipid molecule. 2-ethyl-1-hexanol is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 2-ethyl-1-hexanol can be found in a number of food items such as fats and oils, cereals and cereal products, fruits, and tea, which makes 2-ethyl-1-hexanol a potential biomarker for the consumption of these food products. 2-ethyl-1-hexanol can be found primarily in feces and saliva. 2-ethyl-1-hexanol exists in all eukaryotes, ranging from yeast to humans. 2-Ethylhexanol (abbreviated 2-EH) is a branched, eight-carbon chiral alcohol. It is a colorless liquid that is poorly soluble in water but soluble in most organic solvents. It is produced on a massive scale for use in numerous applications such as solvents, flavors, and fragrances and especially as a precursor for production of other chemicals such as emollients and plasticizers. It is encountered in natural plant fragrances, and the odor has been reported as "heavy, earthy, and slightly floral" for the R enantiomer and "a light, sweet floral fragrance" for the S enantiomer (Wikipedia). xi-2-Ethyl-1-hexanol is found in alcoholic beverages. xi-2-Ethyl-1-hexanol occurs in corn, olive oil, tobacco, tea, rice, tamarind, grapes, blueberries etc..
