1. A salt or ester of lactic acid. 2. To produce milk in the mammary glands.
- l. dehydrogenase (LDH) name for a number of enzymes, including: l-l. dehydrogenase (cytochrome), d-l. dehydrogenase (cytochrome), l-l. dehydrogenase, and d-l. dehydrogenase. The first two enzymes transfer hydrogen to ferricytochrome c or to cytochrome b 2, the last two enzymes transfer it to NAD+, in catalyzing the oxidation of l. to pyruvate; the isozyme distribution of heart and muscle l. dehydrogenase is of significant use in cases of myocardial infarction; a deficiency of a subunit will result in myoglobinuria after intense exercise. SYN: lactic acid dehydrogenase.
- excess l. the increase in l. concentration beyond what would be expected from the increase in pyruvate concentration resulting from a change in redox potential; used as an index of anaerobic carbohydrate metabolism.
- Ringer l. SYN: Ringer solution.
