Question

Describe the difference between HDL and LDL, from a chemical standpoint.

Answer 1

HDL-High density lipoproteins,

LDL-Low density lipoproteins.

=> HDL is smallest and densest of the lipoproteins.

=> It contains comparatively low fat content compared to protein, with a core comprised mainly of cholesterol.

=> HDL collects excess cholesterol and transports to the liver to be broken down and removed.

=> It clings tightly to the cholesterol it carries, ensuring none gets loose and attaches itself to the walls of your arteries.

LDL => The particles in LDL are roughly twice as big as high-density lipoproteins and, are lower in density because they have a higher fat to protein ratio.

=> Although it is referred to as ‘bad’ cholesterol, LDL is still important as it is the primary transporter of cholesterol in your bloodstream, and is crucial for hormone production and the rebuilding of cell structures.

=> However, too much LDL can have a detrimental impact on your health.

=> An excess of LDL in the bloodstream can lead to a buildup of cholesterol and other substances in the arteries called plaque.
