Tissues were collected during the Amsterdam (Netherlands) study of Carbohydrate Regulation of Lipid Metabolism ("SODA").  Subjects were divided between those with and without Metabolic Dysfunction Associated Steatotic Liver Disease (MASLD); subjects were further divided by insulin resistance as assessed by hyperinsulinemic-euglycemic clamp.  Prior to bariatric surgery, subjects were given a glucose or fructose drink.  Subcutaneous and omental adipose tissues were collected during bariatric surgery.  Proteomic data was collected from both subcutaneous and omental adipose tissue; and from subjects given either carbohydrate drink (fructose or glucose).
