10 paź 2020 · This review focuses on the current understanding of carbon flux in gluconeogenesis, including substrate contribution of various gluconeogenic precursors to glucose production. Alterations of gluconeogenic metabolites and fluxes in T2DM are discussed.
In this review, we will provide a brief historical perspective and current views of the in vivo methodologies used to measure gluconeogenesis and glycogenolysis, discuss their advantages and limitations, and summarize the applicability of these measurements in understanding normal and pathophysiological conditions.
16 paź 2020 · Increased gluconeogenesis is a major contributor to the hyperglycemia seen in T2DM. Isotope tracer experiments in humans and animals over several decades have offered insights into gluconeogenesis under euglycemic and diabetic conditions.
23 paź 2020 · Key Points. Carbon isotopes, 14 C and 13 C, in atmospheric CO 2 are changing in response to fossil fuel emissions and other human activities. Future simulations using different SSPs show continued changes in isotopic ratios that depend on fossil fuel emissions and, for 13 C, BECCS.

16 lut 2024 · When glucose is chemically "burned" as a fuel to produce carbon dioxide (CO 2) and water (H 2 O), the energy released from this oxidation process is 670 kcal/mol of glucose: C 6 H 12 O 6 + 6 O 2 → 6CO 2 + 6 H 2 O ΔH = -670 kcal/mol
1 gru 2019 · TDLAS measures the mixing ratios of stable isotopes of carbon dioxide in the air (e.g., the isotopologues, 12 C 16 O 2, 13 C 16 O 2 and 16 O 12 C 18 O) by comparing the infrared absorption of sample and reference gases in a specific absorption line of the spectrum (Santos et al., 2012).
