Usage: technical; chemistry; pharmacology

Examples

• The lipophilicities of different drug compounds determine how well they can cross cell membranes.
• Researchers compared the lipophilicities of several pesticides to predict their environmental persistence.
• High lipophilicities can lead to accumulation of substances in fatty tissues.
• The lipophilicities of these molecules were measured using partition coefficients.
• Understanding lipophilicities is essential for designing effective pharmaceutical agents.
