Do you know how to evaluate fatty acid oxidation (FAO, F-pathway) avoiding to overestimate it? Did you know that malate alone might support mt-respiration in mitochondrial preparations, if malate anaplerotic pathways (e.g. mt-malic enzyme) are present? - Learn more about - »malate anaplerotic pathway control state« - DatLab 7.4 provides a step-by-step guide through the SUIT-027 to evaluate the malate anaplerotic pathway - »SUIT-027« - Since F-pathway can be overestimated due to anaplerotic reactions, SUIT-002 was specially designed to give information on F-pathway in OXPHOS state avoiding FAO overestimation in the presence of anaplerotic pathways - »SUIT-002«
