17-beta Hydroxysteroid Dehydrogenase III Deficiency
smpdb.ca/view/SMP0000356Disease17-beta hydroxysteroid dehydrogenase III deficiency, also known as 17-KSR deficiency or male pseudohermaphroditism with gynecomastia (MPH), is as rare inborn error of metabolism (IEM) and autosomal recessive disorder of the androgen and ...
Aromatase Deficiency
smpdb.ca/view/SMP0125782DiseaseAromatase deficiency is a rare inborn error of metabolism (IEM) and autosomal recessive disorder of mutations in the CYP19A1 gene. The CYP19A1 gene encodes for the enzyme aromatase. Aromatase converts androgens to estrogens which is vita...
Simvastatin Action Pathway
smpdb.ca/view/SMP0000082Drug actionSimvastatin, the methylated form of lovastatin, is an inactive lactone that is metabolized in vivo to β,δ-dihydroxy acid, its most potent metabolite. … The active hydroxy acid is structurally similar to the reduced reaction intermediate and competes with HMG-CoA for binding to HMG-CoA reductase.

smpdb.ca/view/SMP0000119Drug actionHMG-CoA reductase is the enzyme responsible for the conversion of HMG-CoA to mevalonic acid, the rate-limiting step of cholesterol synthesis by this pathway. … Fluvastatin bears a chemical resemblance to the reduced HMG-CoA reaction intermediate that is formed during catalysis. Fluvastatin was the first synthetically-prepared HMG-CoA reductase inhibitor.

Steroid Biosynthesis
smpdb.ca/view/SMP0000023MetabolicThis compound is then reduced to mevalonic acid via the enzyme HMG-CoA reductase. … The resulting mevalonic acid (or mevalonate) is then phosphorylated by the enzyme known as mevalonate kinase to form mevalonate-5-phosphate, which is then phosphorylated again by phosphomevalonate kinase
