Succinate dehydrogenase or SDH is an enzyme involved in the Kreb's cycle. It oxidizes succinate to fumarate. It is also known as succinate-coenzyme Q reductase or respiratory Complex II.

ME/CFS[edit | edit source]

A small study of chronic fatigue syndrome patients found an inversion of the cytochrome oxidase/succinate dehydrogenase ratio in muscle biopses.[1]

A study of poliovirus found that polio infection rapidly decreases cellular oxygen consumption (and thus energy production through cellular respiration) by inhibiting succinate dehydrogenase and blocking mitochondrial electron transport.[2]
