HDL is smaller than LDL.

Low levels of LDLs together with high levels of HDLs are associated with heart disease.

HDL removes cholesterol from the bloodstream.

HDL is more dense than LDL.

LDL has a higher lipid content than HDL.

HDL is considered to be "bad cholesterol."

Answer 1

• HDL is smaller than LDL. TRUE ( HDL with a diameter of 10.8 nm and the highest protein-to-lipid ratio.)

• Low levels of LDLs together with high levels of HDLs are associated with heart disease. FALSE (HIGH HDL AND LOW LDL PREVENTS HEART DISEASES)

• HDL removes cholesterol from the bloodstream. TRUE (IT PUSHES THE FREE CHOLESTEROL IN THE BLOOD INTO THE CELLS MAINLY LIVER SO THAT LIVER CAN BREAK UP THE CHOLESTEROL AND PREVENTS CONDITIONS LIKE ATHEROSCELEROSIS).

• HDL is more dense than LDL. TRUE (THE NAME SUGGESTS IT, HIGH DENSITY LIPOROTEIN AND LOW DENSITY LIPOPROTEIN)

• LDL has a higher lipid content than HDL. TRUE (LIPIDS HERE ARE TRIGLYCERIDES, LDL HAS MORE TRIGLYCERIDES AND LESS PROTEINS IN ITS CORE WHICH IS THE OPPOSITE OF HDL)

• HDL is considered to be "bad cholesterol." FALSE (IT IS CONSIDERED AS GOOD CHOLESTEROL AND IT IS DESIRED IN HIGH AMOUNTS IN OUR BODY)
