Enzymes of energy-producing metabolism in human tear fluid

In human tear fluid the activity of 12 enzymes of energy-producing metabolism was determined. Rather high values were found for lactate dehydrogenase (LDH), pyruvate kinase (PK), malate dehydrogenase (MDH) and amylase (AM). Lower values were found for aldolase (ALD), isocitrate dehydrogenase (ICDH),...

More Information
Summary:In human tear fluid the activity of 12 enzymes of energy-producing metabolism was determined. Rather high values were found for lactate dehydrogenase (LDH), pyruvate kinase (PK), malate dehydrogenase (MDH) and amylase (AM). Lower values were found for aldolase (ALD), isocitrate dehydrogenase (ICDH), glutamate dehydrogenase (GLDH), glucose-6-phosphate dehydrogenase (G-6-PDH), sorbitol dehydrogenase (SDH), hexokinase (HK), glutamate-oxalacetate transaminase (GOT) and glutamate-pyruvate transaminase (GPT). The enzyme pattern of tear fluid is similar to that of the lacrimal gland.
