Modifications on lysine residues, with formation of carboxylmethyl-lysine (CML), malondialdehyde (MDA) and hexitol-lysine are advanced glycation end-products (AGE), and the coupling with reactive aldehyde compounds, such as 4-hydroxynonenal (4-HNE) may appear from lipid oxidation (Guichardant et al., 1998). These modifications feature the oxidative byproducts which react with NH2 groups and form Schiff-base adducts (Mark et al., 1996).

LDL treated with HNE or oxidatively modified by Cu++ or by cultured endothelial cells give rise to Michael addition-type HNE adducts that are recognized by HNE-specific antibodies.
