Subfractional spectrum of plasma low-density lipoproteins in people with normal body weight and patient with obesity was studied by gradient electrophoresis (3-12%) in polyacrylamide gel. Low-density lipoprotein subfractions in fasting patients with abdominal and gluteofemoral obesity were primarily presented by small particles (compared to people with normal body weight). The composition of low-density lipoprotein subfractions underwent most pronounced changes in patients with abdominal obesity after single fat load.
