Question

Quizplus · Accepted Answer

Glucose is not an amphipathic molecule. Amphipathic molecules have both hydrophobic (water-repelling) and hydrophilic (water-attracting) parts, which is characteristic of phospholipids, integral membrane proteins, glycolipids, and connexons. Glucose, however, is entirely hydrophilic and does not have a hydrophobic part, making it not amphipathic.
