Topic 3 Cytoplasmic membrane acts as abarrier to trap solutes in the cytoplasm at concentrations higher than the environment, selectively permeable 3.1 Overview of the composition and structure of cell membranes Bacterial and achaeal cells the cell membrane is called cyctoplasmic membrane Cell membrane is generally referred to as plasma membrane in eukaryotic cells Amino acid is hydrophilic part of a phospholipid Amphipathic is both hydrophobic and hydrophilic parts Hydrophobic molecules are water insoluble Phospholipids have hydrocarbon tails and phsphourous heads Each bilayer layer is called a leaflet A vesicle is simply a bilayer made of phospholipids 3.2 Chemical concepts necessary to understand High O > N > S = C ~H = P Low Polar groups make a molecule more water soluble Covalent bonds (polar and non polar) > Ionic Bonds > Ion – Permanent dipole bonds > Permant dipole – Permanent dipole bonds (Hydrogen bonds) >Permanent – induced dipole bonds > Induced dipole – Induced dipole. Polar groups that contain atoms such as
