It has been postulated that the concentration of large HDL particles more accurately reflects protective action, as opposed to the concentration of total HDL particles. [14] This ratio of large HDL to total HDL particles varies widely and is measured only by more sophisticated lipoprotein assays using either electrophoresis (the original method ...
A lipid profile or lipid panel is a panel of blood tests used to find abnormalities in blood lipid ( such as cholesterol and triglycerides) concentrations. [not verified in body] The results of this test can identify certain genetic diseases and can determine approximate risks for cardiovascular disease, certain forms of pancreatitis, and other diseases.
Total cholesterol is defined as the sum of HDL, LDL, and VLDL. Usually, only the total, HDL, and triglycerides are measured. For cost reasons, the VLDL is usually estimated as one-fifth of the triglycerides and the LDL is estimated using the Friedewald formula (or a variant): estimated LDL = [total cholesterol] − [total HDL] − [estimated ...
Total cholesterol: 3.0, [65] 3.6 [14] [65] 5.0, [5] [66] 6.5 [14] ... LDL/HDL quotient: n/a: 5 [5] (unitless) Tumour markers ... The INR is a corrected ratio of a ...
Hypercholesterolemia, also called high cholesterol, is the presence of high levels of cholesterol in the blood. [1] It is a form of hyperlipidemia (high levels of lipids in the blood), hyperlipoproteinemia (high levels of lipoproteins in the blood), and dyslipidemia (any abnormalities of lipid and lipoprotein levels in the blood).

Blood lipids (or blood fats) are lipids in the blood, either free or bound to other molecules.They are mostly transported in a phospholipid capsule, and the type of protein embedded in this outer shell determines the fate of the particle and its influence on metabolism.
In enzymology, a cholesterol oxidase (EC 1.1.3.6) is an enzyme that catalyzes the chemical reaction. cholesterol + O 2 cholest-4-en-3-one + H 2 O 2. Thus, the two substrates of this enzyme are cholesterol and O 2, whereas its two products are cholest-4-en-3-one and H 2 O 2.
