Reactive aldehyde
WebReactions with Organometallic Compounds. Aldehydes and ketones are excellent electrophiles due to the high δ+ charge on the carbon atom of C=O group. Thus, they react … WebMDA is a highly reactive three-carbon dialdehyde produced as a byproduct of polyunsaturated fatty acid peroxidation and arachidonic acid metabolism [114]. MDA is also a reactive species occurs naturally and is a one of a biological marker for oxidative stress, mostly existing in the enol form.
