Metabolite Identification
Common NameMalonic semialdehyde
DescriptionMalonic semialdehyde belongs to the class of organic compounds known as 1,3-dicarbonyl compounds. These are carbonyl compounds with the generic formula O=C(R)C(H)C(R')=O, where R and R' can be any group. Malonic semialdehyde is an extremely weak basic (essentially neutral) compound (based on its pKa). Malonic semialdehyde exists in all living organisms, ranging from bacteria to humans.
