Reactive dicarbonyls
WebJan 21, 2024 · A key to improving treatment may be targeting highly reactive molecules called dicarbonyls that rapidly bind to the main HDL protein, apoA1, forming adducts that impair HDL function. Adduct formation has been linked to increased inflammation and immune cell activation, as well as plaque formation in arteries and cell death. WebConclusions: Higher habitual consumption of the dicarbonyls MGO and 3-DG was associated with better insulin sensitivity and with lower prevalence of type 2 diabetes, …
