What else can I help you with?
What is the outer layer of lipoproteins made of?
The outer layer is made of amphipathic phospholipids, free cholesterol, and apolipoproteins.
What are the 3 groups of complex lipids?
The three groups of complex lipids are phospholipids, glycolipids, and lipoproteins. Phospholipids are essential components of cell membranes, glycolipids play a role in cell recognition and cell signaling, and lipoproteins transport lipids in the bloodstream.
What are high-density lipoproteins made of?
High-density lipoproteins are made of lipoprotein particles, several proteins, some cholesterol, phospholipids, and a few triacylgylcerol.
What is the core of lipoproteins made of?
The core is made of cholesterol and triacygylcerols. It is hydrophobic.
What molecules carry cholesterol through the blood stream?
Cholesterols, as well as exogenous (from diet) triacylglycerols, are transported, from the intestines to the tissues through the blood stream, by lipoproteins called chylomicrons, globular micellelike particles that consist of a nonpolar core of triacylglycerols and cholesteryl esters surrounded by an amphiphilic coating protein, phospholipid, and cholsterol.
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.
Which organ forms lipoproteins?
The liver produces lipoproteins.
How many kinds of lipoproteins are there?
There are five major types of lipoproteins
What do lipoproteins transport?
HDL'S ( high density lipoproteins) transport cholesterol from the bloodstream to the liver to be degraded and excreted. LDL'S are somties refferred to as carrying the "bad" cholesterol, whereas HDL'S carry the "good" cholesterol.
Are lipoproteins produce by the small intestine?
yes, they can be..these lipoproteins are known as Chylomicrons.
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)
The substances that serve as the major vehicles for fat transport in the bloodstream are?
The substances that serve as the major vehicles for fat transport in the bloodstream are lipoproteins, specifically chylomicrons, very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). These lipoproteins carry fats, such as triglycerides and cholesterol, to various tissues in the body for energy production or storage.
