Presentation Transcript

What are lipoproteins
What are lipoproteins?

  • Lipoproteins are molecules produced in the body and act as lipid transporters

  • They consist of:

    • Triglycerides

    • Protein

    • Phospholipids

    • Free cholesterol



Chylomicrons
Chylomicrons

  • Carry fat from the intestine to the liver

  • Along the way it drops off fat in adipose tissue (for storage)

  • Only present in blood 2 -10 hours after a meal


VLDL

  • Stands for very low density lipoprotein

  • Lipids made in the liver, or those collected from chylomicron remnants are packaged into VLDL and then transported to other parts of the body



LDL triglycerides causing the VLDL to shrink. This causes the VLDL to become more dense, as it loses fat.

  • VLDL’s lose so much fat that they eventually become LDL’s

  • Low Density Lipoproteins

  • LDL’s are cholesterol rich

  • Circulates through the body to be taken up

  • It will return to the liver, however if it is not needed, then LDL will remain in the blood


HDL triglycerides causing the VLDL to shrink. This causes the VLDL to become more dense, as it loses fat.

  • High density lipoprotein

  • Made in liver to collect extra and unwanted cholesterol


Why do you need to worry about ldl and hdl
Why do you need to worry about LDL and HDL? triglycerides causing the VLDL to shrink. This causes the VLDL to become more dense, as it loses fat.

  • High HDL represents cholesterol returning to the liver

  • High LDL is associated with heart disease, heart attack

  • Remember that HDL and LDL are the same, the only difference is the proportions of lipids to proteins in each
