Structure-Activity Relationship (SAR)
Explore the structure-activity relationship (SAR), which explains the connection between a molecule's chemical structure and its biological effect. Learn how changes to a drug's structure can impact its activity and potency. Discover how SAR studies optimize drug candidates and reveal drug-receptor interactions.
