Question

Quizplus · Accepted Answer

The skin patch is designed to release a chemical that can be absorbed through the skin and enter the bloodstream to prevent conception. Lipid-soluble substances are the best choice for this purpose because they can easily penetrate the skin's lipid layer and dissolve in the body's fat tissue, allowing for sustained release and effectiveness. Proteins, water-soluble substances, carbohydrates, and amino acids are less likely to be effective as they would have difficulty crossing through the skin barrier and entering circulation in the required amounts.
