Functions: needed by cell membranes, helps hormones, helps get vitamin "D", the factor that makes brain cells what they need to make connections making it needed for learning and memory.
HDL- High density ibrophien.
LDL- low density iboproien.
Because its a lipid, Cholesterol doesn't ix with water so it attaches to its self with proteins. ( called iboprotien)
LDL- has proteins called b-100 proteins.
HDL- has proteins called a-1 a-11.
Both transfer cholesterol.
Low density transfers it to the cells in the body while high density carries it away from the heart to the liver for the body.
Why are they monitored? Because it can help determine the patients risk for heart problems.
How is it associated with heart disorders? Because an off balance of hdl and ldl can cause build up in the arteries of the heart.
Triglycerides, blood sugar level, and total cholesterol are also monitored with hdl and ldl.
Results of tests- The test result will show in in milligrams and if you have a high hdl ( which is good) means you have a less risk of heart disease but if ldl isn't where its supposed to be at ( too high) , you have a higher risk of heart disease.
What can a patient do? -
A healthy diet makes a world of a difference, it will help rise hdl and lower ldl and excerise will rise hdl by 5% if you do it for 30 min a day.
How does intake of unsaturated fats and saturated fats and trans fats affect cholesterol? It effects it because fats cannot be disolved in water or blood so its carried using ldl's , hdl's ,and lipids but when theres too much, theres not enough to carry all the fat and cholesterol so it attaches it to the sides of the arteries which can cause further medical problems if not taking care of.
