Dietary glucose and fructose are both efficiently assimilated by the liver but a comprehensive measurement of this process starting from their conversion to sugar phosphates, involvement of the pentose phosphate pathway (PPP), and conversion to glyco

Objective Pulsatile insulin secretion is impaired in diseases such as type 2 diabetes that are characterized by insulin resistance. This has led to the suggestion that changes in insulin pulsatility directly impair insulin signaling. We sought to exa

Water enriched with oxygen-18 (H2 18 O) is a potential tracer for evaluating the sources of glucose and glycogen synthesis since it is incorporated into specific sites of glucose-6-phosphate via specific enzyme-mediated exchange/addition mechanisms.

Insulin is secreted into the portal vein in a pulsatile manner. Portal vein insulin concentrations directly and rapidly alter endogenous glucose production (EGP). Pulse frequency has been inversely correlated with hepatic insulin action in some, but

BACKGROUND: While saturated fat intake leads to insulin resistance and nonalcoholic fatty liver, Mediterranean-like diets enriched in monounsaturated fatty acids (MUFA) may have beneficial effects. This study examined effects of MUFA on tissue-specif

Sources of plasma glucose excursions (PGE) following a glucose tolerance test enriched with [U-(13)C]glucose and deuterated water were directly resolved by (13)C and (2)H Nuclear Magnetic Resonance spectroscopy analysis of plasma glucose and water en

Purpose The positional analysis of hepatic glycogen enrichment from deuterated water (2 H2 O) by 2 H NMR has been applied previously to resolve the contributions of glucose and fructose to glycogen synthesis in rodents fed a high sucrose diet. To fur

p-Aminobenzoic acid (PABA) was evaluated for noninvasive sampling of UDP-glucose in the liver. Six healthy subjects ingested 550 mg PABA during a breakfast meal. Urine was collected 0–2 and 2–4 h after PABA ingestion. N-acetyl PABA glucuronide (N
