High-density lipoproteins (HDL) are composed mainly of proteins, with only small amounts of cholesterol. HDLs are often referred to as "good cholesterol" because they help remove cholesterol from artery walls and transport it to the liver for elimination from the body. Higher HDL levels actually protect against coronary Heart disease.
Low-density lipoproteins (LDL) are composed mainly of cholesterol and have very little protein. They are often referred to as "bad cholesterol" because they are primarily responsible for depositing cholesterol within arteries. High levels of LDLs are associated with an increased risk for coronary heart disease.
thanks x
What else can I help you with?
What are some good cholesterol foods?
There are many good Cholesterol foods. There are two types of Cholesterol, HDLs, and LDLs. HDLs are the good type of cholesterol, and these are items are mostly fruits (eggs are a good source of HDLs too!). LDLs are the bad Cholesterol, avoid them at all costs if you want a better HDL count. Fish and Nuts are examples of LDLs.
What is the consequence of high ldl and low hdl in a patient?
LDLs are 'low density lipoproteins' which are the 'bad cholesterols' in your blood, HDLs are 'high density lipoproteins' which are the 'good cholesterol' (remove unwanted cholesterol from the blood and take it to the liver).Effectively you want more HDLs than LDLs otherwise you end up with too much cholesterol in your blood which can 'clog' up your blood vessels causing a cardiovascular attack/coronary heart disease.
Is cholesterol a monomer or polymer?
Cholesterol is a big molecule, C27H46O. However, it is a single molecule, and thus a monomer. In cells cholesterol is normally embedded in cell membrane and makes hydrogen bonds with surrounding molecules. In the blood, it is also not found alone, but packaged with lipids (triglycerides) and lipoproteins. Thus when looking at cholesterol levels in the blood, people often refer to HDLs and LDLs. The proteins in HDLs and LDLs are also discrete units with a specific structure, but they are considered to be polymers of amino acids.
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 :)
Which type of cholesterol is good for you LDLs or HDLs why?
HDLs are good cholesterol and LDLs are bad for you. LDL stands for Low Density Lipoproteins and they stick to the inside of the arteries, narrowing them and making blood pressure higher. If one of the 'plaques' is knocked off, it can block the bloodstream causing a heart attack.
What is the function of HDL?
HDls- High Density Lipoproteins: They are seen as 'good cholesterol', as they are mainly protein. They bind to LDLs (bad cholesterol) and transport them to the liver, were they are stored. They are seen as helpful because they reduce risks of Heart related illnesses/diseases.
Are LDLs high in cholesterol?
The LDLs are overloaded with cholesterol
Cells acquire LDLs by?
Low-density lipoproteins or LDLs are substances made up of fat and protein. Cells acquire LDLs through receptor-mediated endocytosis, wherein specific molecules are ingested into the cell.
What is the smallest form of fat?
LDLs
Why can hdls be a problem?
coz its a jokes ting
How do HDLs and LDLs differ structurally?
Types of lipoproteins differ in density, lipid composition, and function. They include very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL), and high-density lipoprotein (HDL). LDL's have a density of 1.006-1.063 g/mL, made up of 6% Triacylglycerol, 22% Phospholipids, 8% Cholesterol, 42% Cholesteryl esters, and 22% Protein. HDL's have a density of 1.063-1.210 g/mL, made up of 4% Triacylglycerol, 24% Phospholipids, 2% Cholesterol, 15% Cholesteryl esters, and 55% Protein.To summarize, LDLs have more lipid and less protein, therefore less dense. HDLs are protein rich and dense.Also, they differ in their function. LDL's deposit extra cholesterol in arteries, while HDL's move cholesterol to the liver.
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".
