说明

General description

Crotonaldehyde(2-Butenal) is an α, β-unsaturated aldehyde and extremely reactive compound. It serves as a chemical building block in the production of solvents, sorbates, and, to a lower extent, pharmaceuticals and aroma compounds. Additionally, it can be used as an alcohol denaturant, in leather tanning and in the manufacturing of rubber accelerators.

Application

Crotonaldehyde is used:

In the manufacturing of sorbic acid that are widely employed as food preservatives to avoid the food spoilage by microorganisms.

Formation of cyclic 1,N2-propanodeoxyguanosine adducts in DNA upon reaction with acrolein or crotonaldehyde.

F L Chung et al.

Cancer research, 44(3), 990-995 (1984-03-01)

Acrolein reacted with deoxyguanosine at pH 7 and 37 degrees to give three major products, Adducts 1 to 3, which were separated by high-performance liquid chromatography. They were identified by their ultraviolet, mass, and nuclear magnetic resonance spectra, by the

Effect of protein modification by malondialdehyde on the interaction between the oxygen-evolving complex 33 kDa protein and photosystem II core proteins.

Yasuo Yamauchi et al.

Planta, 231(5), 1077-1088 (2010-02-17)

Previously we observed that the oxygen-evolving complex 33 kDa protein (OEC33) which stabilizes the Mn cluster in photosystem II (PSII), was modified with malondialdehyde (MDA), an end-product of peroxidized polyunsaturated fatty acids, and the modification increased in heat-stressed plants (Yamauchi
