Used in biomedical research to quantify D-lactate dehydrogenase levels in human samples, aiding in the study of metabolic disorders, mitochondrial dysfunction, and conditions linked to elevated D-lactate such as short bowel syndrome and lactic acidosis. Enables researchers to assess enzyme activity indirectly through concentration measurements in serum, plasma, or tissue homogenates. Supports clinical investigations into gut microbiome metabolism and energy pathways. Widely applied in diagnostic laboratories and pharmaceutical research for biomarker validation and monitoring disease progression.
