Where are very low-density lipoproteins made?
They are made in the liver
How is the production of endogenous very low-density lipoproteins decreased?
Exercise
What are the 4 major lipoproteins?
(See link below)Chylomicrons are the least dense of all the lipoproteins and are basically just big balls of fat (triglycerides), with a makeup of about 90 percent fat, a touch of phospholipids, some cholesterol, and a smidgin of protein.VLDL (very low-density lipoprotein) carries a great amount of fat, some phospholipids, and cholesterol. The high fat content of VLDL makes a large quantity of this lipoprotein in the blood undesirable.LDL (low-density lipoprotein, or "bad" cholesterol) has only a fraction of the fat and double the protein of VLDL and is very high in cholesterol. This lipoprotein carries the majority of cholesterol in the blood and is considered the unhealthy one.HDL (high-density lipoprotein, or "good" cholesterol) is a spherical blob of mostly protein (albeit a type different from that found in LDL), some cholesterol, phospholipids, and very little fat. The densest of all the lipoproteins, HDL is the healthy one.
What are fibric acid derivatives?
Although these drugs are less effective than the statins at lowering total cholesterol, they may be able to lower the low-density lipoprotein (LDL) cholesterol while raising the high-density lipoprotein (HDL) cholesterol.
A carrier molecule is required for?
Blood is mostly aqueous and will dissolve ionic compounds. Cholesterol is organic and does not dissolve in water. High density and low density lipo-proteins [LDL and HDL] are needed to carry the otherwise insoluble cholesterol within and throughout the Blood.
What is the function of Low-density lipoprotein?
The function of low density lipoproteins are to carry cholesterol molecules through the body. The cholesterol can be used in membranes for transport or to make hormones.
What are Intermediate-density lipoproteins?
IDLs are short-lived lipoproteins containing about 30% cholesterol that are converted in the liver to low-density lipoproteins (LDLs)
How does cholesterol help?
Cholesterol is transported around the body by lipoproteins, which is fat attached to protein. There are two types - HDLs (high density lipoproteins) and LDLs (low density lipoproteins)LDLs carry cholesterol from the liver to body cells. Too much can block arteries. So this is "bad cholesterol"HDLs carry cholesterol that isn't needed from body cells back to the liver for removal from the body. So these are "good cholesterol"Hope I helped :)
What are the test under of lipid profile?
1. The tests under a lipid profile are: · Total cholesterol · Triglyceride · Low Density Lipoproteins (LDLs) · High Density Lipoproteins (HDLs) · Very Low Density Lipoproteins (VLDLs) · Total cholesterol/HDL cholesterol ratio · Lipoprotein electrophoresis
Endogenously produced cholesterol is packaged in for delivery to cells of the body?
low-density-lipoproteins
A high risk of heart attack correlates with high blood levels of what?
A high risk of heart attack correlates with high blood levels of low-density lipoproteins. Lipoproteins are responsible for transporting triacylglycerol's and cholesterol in the blood among all the tissues in the body.
What delivers the cholesterol that contributes to plaque formation in the lining of the arteries?
LDLs ( low density lipoproteins) that's why the cholesterol in combination with LDLs is called " bad cholesterol".
What does LDL cholesterol mean?
LDL (low-density-lipoproteins)- transport cholesterol to body cells where they are used in various ways. It is also called the bad cholesterol. HDL (high-density-lipoproteins)- transport cholesterol from the tissue cells (or arteries) to the liver for disposal in bile.For this purpose it is called the good cholesterol.
What are the differences between HDL and LDL cholesterol?
The low-density lipoproteins transport cholesterol from the liver to specific cells and the high-density lipoproteins remove excess cholesterol from the body cells and return it to the liver where it can be excreted in bile.
What lipoprotein has the highest percentage of cholesterol?
LDL. Low Density Lipoproteins per clinical nutrition book, they're approximately half cholesterol which accounts for their role in heart disease.
What exactly is ldl cholesterol?
LDL is a low density lipoproteins which flows with our blood. Because of its very nature of low density and very low amount of mass, sometimes it gets stuck inside the walls of blood vessels. If deposits gets accumulated over a period of time, it causes blockage to the healthy flow of blood causing more strain on our heart to pump the blood through narrowed blood vessels leading to heart attack/cardiac arrest.
What are low density lipoproteins?
Low density lipoproteins are the second smallest of the five major groups of lipoproteins. They enable the transport of fat molecules within the water around cells and within the bloodstream.
