We purchased quercetin powder from China and we don't know if we should use the molecular weight of just quercetin or quercetin dihydrate since it is already in powder form. Is there a difference?
You might find information from this link.

When looking for quercetin, the form of dihydrate has the apparent best bioavailability followed by glycosides, aglycone, and finally rutinoside.
It has a couple of crystallyzation wáter. Has a better dissolution kinetics.
Could you advise me on a simple technic for DNA sequence & termination definition (characterization) ? (I am non-biologist). Which parameters should I take in consideration ? Thank you
