What is a Malonaldehyde (C₃H₄O₂)?

Malonaldehyde (C₃H₄O₂) is an organic compound belonging to the aldehyde family. It consists of two aldehyde groups (-CHO) attached to a central malonic acid backbone. Malonaldehyde is commonly formed as a byproduct in the oxidation of lipids, particularly during oxidative stress within cells.

It is often detected as a degradation product or end product of lipid peroxidation, and its accumulation in the body can lead to cellular and tissue damage. High levels of malonaldehyde have been associated with aging and diseases, especially cardiovascular and neurodegenerative conditions. Therefore, malonaldehyde is frequently used as a biomarker for oxidative stress in biological studies.
