Answer 1

The answer to your query is as follows:

Q7. Difference between HDL and LDL Cholesterol.

LDL	HDL
It stands for low density lipoprotein.	It stands for high density lipoprotein.
It is also known as bad cholesterol.	It is also known as good cholesterol.
It is a type of lipoprotein that is made up of moderate proportions of protein and triglyceride and a very high proportion of cholesterol.	It is a type of lipoprotein that is made up of high proportions of protein with little triglyceride and cholesterol.
It is responsible for the formation of thick and hard plaques along the lining of blood vessels.	It scavenges LDL and reduces the level of cholesterol in the blood.
Diameter of LDL is 18 - 25 nm.	Diameter of HDL is 5 - 12 nm.
It carries lipid molecules throughout the body.	The lipid molecules are collected from the tissues and brought back to the liver.

Q8. The heart attack risk factor ratio is determined by calculating the non-HDL cholesterol level.Non-HDL cholesterol subtracts the High Density Lipoprotein or HDL from the total cholesterol number.

An optimal level of non-HDL cholesterol is less than 130 milligrams per deciliter (mg/dL), or 3.37 millimoles per liter (mmol/L).

To calculate the cholesterol ratio, divide the total cholesterol number by the HDL cholesterol number.

Higher ratios mean a higher risk of heart disease.

Q9. Atherosclerosis is also known as arteriosclerotic vascular disease. It is a condition in which plaque is build up around the artery wall which makes the artery narrow and hardened.The bad cholesterol gets deposited on the artery wall which disrupt the flow of blood from heart to various body parts.

The word chylomicron is made up of two words "chylo" which means milky and "microns" which means small.So, chylomicrons are small milky fat globules composed of proteins and lipid.They are made in the mucosa of the intestine.They are found in blood and lymphatic fluid and helps to transport fat from small intestine to liver and then to adipose tissue for storing fat.

Hope it helps.
