In animals , -lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase ( LDH ) in a process of fermentation during normal metabolism and exercise . It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal , which is governed by a number of factors , including monocarboxylate transporters , concentration and isoform of LDH , and oxidative capacity of tissues. The concentration of blood lactate is usually ہے ، لیکن شدید مشقت کے دوران 20 ملی مولر سے زیادہ تک بڑھ سکتی ہے ۔
