What is Cholesterol?
LDL and HDL
High density liporotien many times abbreviated as HDL and considered as the "good type of cholesterol" helps remove the plaque like substance of LDL cholesterol from the arteries and returns it back to the liver. High levels of HDL are ideal, low levels of HDL can require serious medical attention.
Not only the functions of LDL and HDL differentiate, but so do their structures. About fifty percent of an LDL structure is cholesterol and approximately twenty-five percent is protein. However. HDL is almost the complete opposite, with half the weight of an HDL structure consisting of protein and only about twenty percent remaining as cholesterol.
