High-density lipoprotein (HDL) is one of the five major groups of lipoproteins. [1] Lipoproteins are complex particles composed of multiple proteins which transport all fat molecules around the body within the water outside cells. They are typically composed of 80–100 proteins per particle (organized by one, two or three ApoA). HDL particles ...
Hyperlipidemia is abnormally high levels of any or all lipids (e.g. fats, triglycerides, cholesterol, phospholipids) or lipoproteins in the blood. [2] The term hyperlipidemia refers to the laboratory finding itself and is also used as an umbrella term covering any of various acquired or genetic disorders that result in that finding. [3]
A class of lipids known as phospholipids help make up what is known as lipoproteins, and a type of lipoprotein is called high density lipoprotein (HDL). [8] A high concentration of high density lipoproteins-cholesterols (HDL-C) have what is known as a vasoprotective effect on the body, a finding that correlates with an enhanced cardiovascular ...
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.
A diet high in sugar or saturated fats increases total cholesterol and LDL. [21] Trans fats have been shown to reduce levels of high-density lipoprotein while increasing levels of LDL. [22] A 2016 review found tentative evidence that dietary cholesterol is associated with higher blood cholesterol. [23]

There are several types of lipoproteins in the blood. In order of increasing density, they are chylomicrons, very-low-density lipoprotein (VLDL), intermediate-density lipoprotein (IDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). Lower protein/lipid ratios make for less dense lipoproteins.
Mutations in this gene have been associated with Tangier disease and familial high-density lipoprotein deficiency. ABCA1 has been shown to be reduced in Tangier disease which features physiological deficiencies of HDL. [22] [23] Leukocytes' ABCA1 gene expression is upregulated in postmenopausal women receiving hormone replacement therapy (HRP ...
