Examples of lipoprotein in the following topics:

  • Regulation of Blood Cholesterol Levels

    • Cholesterol is transported through the blood by lipoproteins which direct cholesterol to where it is needed.
    • Phospholipids and cholesterol, being amphipathic, are transported in the surface monolayer of the lipoprotein particle.
    • For this reason, there are several types of lipoproteins within the blood called, in order of increasing density:
    • The more lipid and less protein a lipoprotein has, the less dense it is.
    • However, the different lipoproteins contain apolipoproteins, which serve as ligands for specific receptors on cell membranes.
  • Absorptive State

    • Chylomicrons are lipoprotein particles that consist of triglycerides (85-92%), phospholipids (6-12%), cholesterol (1-3%) and proteins (1-2%).
    • This main product of fat digestion is first broken down to fatty acids and glycerol through hydrolysis using lipoprotein lipase.
  • Gram-Negative Outer Membrane

    • The peptidoglycan layer is non-covalently anchored to lipoprotein molecules called Braun's lipoproteins through their hydrophobic head.
  • Liver Function

    • A bulk of the lipoproteins are synthesized in the liver.
  • Anabolic Steroids and Muscles

    • Known side effects include harmful changes in cholesterol levels (increased Low density lipoprotein and decreased High density lipoprotein), acne, high blood pressure and liver damage.
  • Basic Structures of Prokaryotic Cells

    • Gram-negative bacteria have a relatively thin cell wall composed of a few layers of peptidoglycan (only 10 percent of the total cell wall), surrounded by an outer envelope containing lipopolysaccharides (LPS) and lipoproteins.
    • In gram-negative bacteria, the cell wall is surrounded by an outer membrane that contains lipopolysaccharides and lipoproteins.
  • Factors Affecting Pulmonary Ventilation: Surface Tension of Alveolar Fluid

    • Surfactant is a lipoprotein molecule that reduces the force of surface tension from water molecules on the lung tissue.
  • Double-Stranded DNA Viruses: Pox Viruses

    • The most abundant and simplest infectious form of the poxvirus particle, the mature virion (MV), consists of the viral DNA genome encased in a proteinaceous core and an outer lipoprotein membrane with approximately 60 and 25 associated viral proteins, respectively.
  • The Work of Breathing

    • Surfactant is a complex mixture of phospholipids and lipoproteins that works to reduce the surface tension that exists between the alveoli tissue and the air found within the alveoli.
  • Metabolomics

    • Macromolecules such as lipoproteins and albumin are reliably detected in NMR-based metabolomics studies of blood plasma.
