Enzymes exist in all biological systems to catalyze vital biochemical reactions. The reactivity of an enzyme and the extent of its influence on product formation can give insight to understanding the physiological changes that can take place. The enzyme HSD17B7, involved in the cholesterol biosynthesis pathway, may play a role in influencing underlying changes during transition of disease, specifically in eyes at normal state to eyes that have glaucoma. In this work, we present a method to test the enzymatic activity level of HSD17B7 between normal and glaucomatous optic nerves to assess whether enzymatic upregulation of cholesterol biosynthesis may play a role in glaucoma.
