    6810   Transport  The Directed Movement of Substances (such As Macromolecules Small Molecules Ions) Into Out of or Within a Cell or Between Cells or Within a Multicellular Organism by Means of Some Agent Such As a Transporter or Pore. 
    6869   Lipid Transport  The Directed Movement of Lipids Into Out of or Within a Cell or Between Cells by Means of Some Agent Such As a Transporter or Pore. Lipids Are Compounds Soluble in an Organic Solvent But Not or Sparingly in an Aqueous Solvent. 
    5783   Endoplasmic Reticulum  The Irregular Network of Unit Membranes Visible Only by Electron Microscopy That Occurs in the Cytoplasm of Many Eukaryotic Cells. the Membranes Form a Complex Meshwork of Tubular Channels Which Are Often Expanded Into Slitlike Cavities Called Cisternae. the Er Takes Two Forms Rough (or Granular) with Ribosomes Adhering to the Outer Surface and Smooth (with No Ribosomes Attached). 
    5789   Endoplasmic Reticulum Membrane  The Lipid Bilayer Surrounding the Endoplasmic Reticulum. 
    5811   Lipid Particle  An Intracellular Non Membrane Bounded Organelle Comprising a Matrix of Coalesced Lipids Surrounded by a Phospholipid Monolayer. May Include Associated Proteins. 
    16020   Membrane  Double Layer of Lipid Molecules That Encloses All Cells and in Eukaryotes Many Organelles; May Be a Single or Double Lipid Bilayer; Also Includes Associated Proteins.
