How do hydrophobic molecules enter a cell
WebAlthough hydrophobic EED peptides pointed us in the right direction, due to the exposed aromatic hydrophobicity, they inserted into the cell membrane, causing cytotoxicity. Consequently, at the current level of development, it is difficult to envision any of these viral or insect toxin peptide approaches moving forward to clinical trials. WebThe hydrophilic heads of phospholipids in a membrane bilayer face outward, contacting the aqueous (watery) fluid both inside and outside the cell. Since water is a polar molecule, it readily forms electrostatic (charge-based) interactions with the phospholipid heads.
