Medium-chain triglycerides (MCTs) are absorbed and metabolized differently from long-chain triglycerides (LCTs). Recent data indicate that MCTs may be useful as a dietary substitute in a variety of clinical disorders. The current studies were undertaken to characterize urinary organic acid excretion in patients with non-insulin-dependent diabetes mellitus during 4 d of an LCT or MCT diet. Urinary excretion of the dicarboxylic acids adipic, suberic, and 3-hydroxysebacic and the (omega-1) hydroxylation products 5-hydroxyhexanoic acid and 7-hydroxyoctanoic acid, was increased during MCT feeding as compared with LCT feeding. Urinary suberic and 7-hydroxyoctanoic acid excretions were increased 55- and 30-fold, respectively, during the MCT-substituted diet. Urinary organic acid profiles provide information on the fate of lipids during MCT feeding and may also be useful in assessing complicance during clinical trials employing MCT-substituted diets.

D003924 Diabetes Mellitus, Type 2 A subclass of DIABETES MELLITUS that is not INSULIN-responsive or dependent (NIDDM). It is characterized initially by INSULIN RESISTANCE and HYPERINSULINEMIA; and eventually by GLUCOSE INTOLERANCE; HYPERGLYCEMIA; and overt diabetes. Type II diabetes mellitus is no longer considered a disease exclusively found in adults. Patients seldom develop KETOSIS but often exhibit OBESITY.
