Nitric oxide (NO) is generated by various cell types, including macrophages and endothelial cells (Radi, 2018)
Recent research have identified that DADS and DATS protect endothelial nitric oxide synthase (eNOS) activity against ox-LDL-induced damage, potentially through modulation of the PI3 K/PKB signaling pathway and inhibition of eNOS degradation (34)
