Why is cholesterol important to the body? Why is it harmful?
Help the cells and maintaining a healthy body. Too much cholesterol can lead to health problems like heart disease and other types of body dysfunctions
What are the 2 main sources of cholesterol?
Produced from the liver and it is also absorbed from the food you eat
What roles do LDL and HDL play in balancing the body's cholesterol levels?
LDL delivers fat and protein through the blood and it is taken and stored in tissues.
HDL removes all the excess cholesterol and reduces the risks of getting adverse health effects
Unsaturated fat: A type of fat that contains a high proportion of fatty acids with at least one double bond. (Olive oil, Salmon, Almonds, etc,) Uses Liquids, oils Unsaturated fats are important to the body because It’s healthy in diets they reduce risks of heart disease and help lower cholesterol.
Saturated fats: A type of fat that contains a high proportion of fatty acids with at least one double bond. (Olive oil, Salmon, Almonds, etc,) (Uses Liquids, oils) It’s less healthy in diets that unsaturated fats. Without saturated fats your white blood cells can’t recognize and destroy invaders like bacteria, viruses and fungi.
Trans fat: Fatty acid in which is turned into a more solid form using hydrogen to liquid vegetable oils. (ground beef) Raise LDL and lower HDL. Eating more trans fat could lead to a stroke or heart disease.
Cholesterol: Compound of sterol type found mostly in body tissue.Cholesterol and its derivatives are important constituents of cell membranes. (olive oil,canola oil,peanut oil, etc) low-density lipoprotein cholesterol, also called "bad"cholesterol) HDL (high-density lipoprotein cholesterol, also called "good"cholesterol) Triglycerides (fats carried in the blood from the food we eat.
The cell membrane: Immobilizes the outer surface of the membrane and makes it less soluble to very small water-soluble molecules that make it pass through more easily.
Learning and memory: Cholesterol is so important to brain function that it is generated independently of cholesterol metabolism in the rest of the body
Digestion and bile acids: Cholesterol, ingested as part of the diet or derived from hepatic synthesis is converted into the bile acids cholic and chenodeoxycholic acids, which are then conjugated to an amino acid (glycerin or taurine) to yield the conjugated form that is actively secreted into canaliculi.
Vitamin D: It helps on the formation of your memories and is vital for neurological function.
Steroid hormones: powerful signal molecules that regulate a host of organism functions.
1. What are LDL and HDL?
LDL: Substance made up of fat and protein, its main function is to carry cholesterol and fats to in the blood….LDL carries cholesterol from the liver and through the blood and it is transported to the tissues in the body where it is stored.
HDL: HDL removes all the excess cholesterol and reduces the risks of getting adverse health effects.
2. How do LDL and HDL differ structurally and functionally?
LDL: 50% of the weight in LDL particles is cholesterol, and 25% is protein.
HDL: 20% of the weight in HDL particles is cholesterol, and 50% is protein.
3. Why do doctors monitor the concentrations of LDL and HDL in patients’ blood?
Doctors monitor LDL and HDL because it can help them determine if the patients are in risk of getting heart diseases.
4. How are the concentrations of LDL and HDL associated with the risk for heart disease and associated disorders?
High levels of LDL cholesterol lead to atherosclerosis which increases the risk of getting a heart attack and a ischemic stroke. HDL cholesterol helps reduce the of cardiovascular diseases because it carries cholesterol away from the blood stream.
5. What other molecules in a patient’s blood are monitored along with LDL and HDL?
Triglycerides, Low Density Proteins, and High Density Proteins.
6. What do the results of a cholesterol test mean? How do patients interpret each value?
a) Your test report shows your cholesterol levels in milligrams per deciliter of blood. With this your doctor can predict your lifetime or the time you will get a heart attack.
b) Depending on the the category, patients should interpret each value differently as each category's results mean different things.
7. What can patients do to change the levels of LDL and HDL in their blood?
A healthy diet will reduce the fat and cholesterol and will increase HDL levels. It will also Decrease LDL levels.
8. How does intake of unsaturated, saturated, and trans fats affect cholesterol levels and overall health?
Knowing what you eat and what fats raise and decrease LDL levels will be the best way of reducing your risk of getting a heart attack.Eating saturated fat,and trans fat raises your blood cholesterol level even further.
