Chronic inflammation plays a significant role in the development and progression of metabolic dysfunction-related diseases. This study investigating a protein hydrolysate from Lupinus angustifolius (LPH) in mice model on a western diet (WD) aimed to elucidate its potential beneficial role in improving the lipidomic and anti-inflammatory profile. To achieve this objective, a lipidomic approach in combination with the evaluation of protein level modulation of selected key enzymes that are pivotal involved in the bioactive lipid pathway synthesis/regulation was performed on liver homogenates. Specifically, LPH positively impacted DHCer, SM, LacCer, Sph 1, DHSph 1, and S1P 1 concentrations, and restored the basal conditions of ASAH1 and ASM, proteins involved in sphingolipid metabolism. LPH also reduced the FASN and PPARγ levels and eicosanoids, with positive modulation of the COX-2 and ALOX5. Additionally, LPH reduced the WB-induced AEA and 2AG concentrations.
