What Is Cholesterol? 4.3.1 Biomed Project by Isabelle Tabar https://padlet.com/20tabari/biomed_cholesterol_project By Izzy Tabar and Nya Reale en-us 2018-03-06 14:29:37 UTC 2023-01-20 22:10:52 UTC hello@padlet.com https://padlet-assets.s3.amazonaws.com/icons/Hearts.png What are LDL and HDL? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/238620987 LDL
  • Low-density lipoprotein that transports cholesterol to and from the cells
  • High levels of LDL may lead to a buildup in the arteries and result  in heart disease.
HDL
  • High-density lipoprotein that removes excess cholesterol from the blood stream
  • Can reduce the risk of heart disease and stroke.

LDL takes cholesterol to the cells and HDL removes excess cholesterol from the blood stream and returns it to the liver. 
Structurally:
Both have a core which contains cholesterol esters and a surface monolayer of phospholipid, unesterifed cholesterol and specific proteins.
LDL: has a high density because of it's high protein:lipid ratio (50:25)
HDL: is high in cholesterol esters and is made up of 20% cholesterol and 50% protein. ]]> 2018-03-06 14:38:36 UTC https://padlet.com/20tabari/biomed_cholesterol_project/wish/238627339 Why do doctors monitor the concentrations of LDL and HDL in patients' blood? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/238633021 In order to evaluate the risk of heart disease and stroke.]]> 2018-03-06 14:45:32 UTC https://padlet.com/20tabari/biomed_cholesterol_project/wish/238633021 How are the concentrations of LDL and HDL associated with the risk for heart disease and associated disorders? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/238637467 High levels of LDL cholesterol raise your risk for heart disease and stroke. They also make up most of the body's cholesterol and are nick-named, "bad" cholesterol.
High levels of HDL cholesterol can lower your risk for heart disease and stroke. They are nick-named, "good" cholesterol because they absorb cholesterol and carry it back to the liver which will help cleanse the body of the excess. ]]> 2018-03-06 14:50:55 UTC https://padlet.com/20tabari/biomed_cholesterol_project/wish/238637467 What other molecules in a patient's blood are monitored along with LDL and HDL? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/238639942 Triglycerides, blood sugar level, and total amount of cholesterol. ]]> 2018-03-06 14:53:51 UTC https://padlet.com/20tabari/biomed_cholesterol_project/wish/238639942 What do the results of a cholesterol test mean? How do patients interpret each value? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/238642442 The results of a cholesterol test determine if the patients cholesterol levels are healthy (or not). For blood pressure, less than 120/80 mm Hg is healthy and their if their BMI is less than 25 kg/m^2, they have good results. These numbers are important because they will help to determine if the patient has a risk for developing cardiovascular disease. ]]> 2018-03-06 14:56:57 UTC https://padlet.com/20tabari/biomed_cholesterol_project/wish/238642442 What can patients do to change the levels of LDL and HDL in their blood? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/239499720 To change the levels of LDL and HDL in their blood a patient should change their diet by lowering their intake of saturated fat. 
They should support their diet by increasing their physical activity and consuming a variety of fruits and vegetables to ensure positive results.]]> 2018-03-08 04:11:54 UTC https://padlet.com/20tabari/biomed_cholesterol_project/wish/239499720 How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health? 20tabari https://padlet.com/20tabari/biomed_cholesterol_project/wish/239502380 Unsaturated fats
  • Help to lower the risk of heart disease and stroke
  • Can help improve blood cholesterol. 
Saturated fats
  • Raises the level of cholesterol in the blood
  • High levels can increase the risk for heart disease and stroke
Trans fats
  • Raise the levels of LDL cholesterol levels and lower HDL cholesterol levels
