    thin barrier controlling substance movement in and out of cells

    The cell membrane, also known as the plasma membrane or plasmalemma, is a thin, flexible barrier that surrounds the cell, providing structure and protection. It is composed of a double layer of lipids (lipid bilayer) with embedded proteins, which control the movement of substances in and out of the cell, thus maintaining the internal environment and facilitating communication with other cells.

      community Does melatonin dissolve in isopropyl alcohol

      in Technology  6 upvotes 1 year ago
      The conversation discusses making a topical melatonin solution for hair loss treatment, questioning if isopropyl alcohol can dissolve melatonin. Melatonin is soluble in lipids and alcohol, but it's unstable and should be mixed fresh regularly; it may help hair growth by affecting certain cellular signaling pathways and has anti-androgenic effects.
