lipoprotein

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.
