MolMeDB is an open chemistry database about interactions of molecules with membranes.

"Open" means that you can send your scientific data to MolMeDB and that others may use it. We collect information on how chemicals interact with individual membranes either from experiment or from simulations. 

How do compounds interact with membranes?

  • They are attracted to membranes, PMF estrone vs estriol
  • they partition to membranes,
  • they reside in specific positions in membranes,
  • they permeate through membranes, 
  • they change the membranes,
  • and many more. 

MolMeDB collects the data in order to help understand these phenomena.

Example: Difference in membrane behaviour between estrone and estriol. Estrone permeates through the membranes much more easily than estriol. It will also partition more into the membranes and it will be more deeply buried. Free energy profiles were calculated with COSMOmic 18.
