  4. 18. Mitochondrial efficiency : focus on dietary nitrate, hypoxia and exercise

    Författare :Tomas Schiffer; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Metabolic efficiency affects weight control, generation of heat, exercise performance and health. The tiny radical nitric oxide (NO) targets several cellular components that can influence metabolic efficiency. NO is produced endogenously from L-arginine and molecular oxygen by specific NO-synthases. LÄS MER
