Red Yeast Rice naturally produces Monacolin K, where the acid form is the bioactive compound directly supporting metabolic health, while the lactone form (Lovastatin) must convert to the acid form in the body to activate its benefits.
The primary difference between Monacolin K (acid form) and Lovastatin (lactone form) lies in their chemical structure and biological activity. Both are inhibitors of HMG-CoA reductase, the key enzyme in cholesterol synthesis, but they have distinct properties:
Conclusion:
Monacolin K (acid) = Active form (direct HMG-CoA inhibition).
Lovastatin (actone) = Prodrug (must convert to acid form in the body).
This difference is crucial for drug metabolism and efficacy in cholesterol-lowering therapy.
