4. Saturated fats increase levels of Low Density Lipoproteins (LDL) increase myocardial infarction (MI) and strokes 5. Neutral fats + cholesterol 6. Transport mostly cholesterol to steriodogenic cells a. Steriodogenic cells: cells that synthesize steroid hormones 7. 3 Types of Lipoproteins (Lipids + proteins): a. Very low Density Lipoproteins (vLDL) a.i. Lipid + proteins=lipidproteins a.ii. Lipids are less dense then proteins a.iii. vLDL & LDL= lipid portion is greater than protein portion a.iii.1. More lipid and less protein b. Low Density Lipoprotein (LDL) = “BAD CHOLESTEROL” b.i. Too much of it will kill you c. High Density Lipoproteins (HDL) = “GOOD CHOLESTEROL” c.i. Transport neutral fats + cholesterol to the liver where cholesterol is degraded and eliminated from the body c.ii. Decreases cholesterol levels in the blood good cholesterol c.iii. HDL: More protein and less lipid 8. TRANS FATS: Unsaturated fats + H+ = Saturated (solid) fats a. Margarine b. Trans fats increase the levels of LDL substantially hence, increasing the chances of developing MI and strokes c. Artificially creates saturated fats which are worse in higher LDL than the naturally occurring saturated fats d. Solidification of the unsaturated fats by the addition of hydrogen e. Trans fats higher LDL Organic: Lipids: Neutral Fats: LDLs 1. Excess LDLs the cholesterol is used to maintain the plasma (cell) membrane “cholesterol maintains the integrity of the plasma membrane” 2. Excessive intake of cholesterol beyond steroid hormone synthesis and maintaining the plasma membrane excess cholesterol is carried in the blood stream as LDLs 3. LDLs settle into the internal surface of the blood vessels forming atherosclerotic plaque 4. Atherosclerosis can lead to myocardial infarction (“heart attack”), ischemic stroke (“brain attack”), or even death. 5. Formation of plaques in large blood vessels leads to hypertension as the plaque impede blood flow through these blood vessel 6. If parts of the atherosclerotic plaques dislodge and become free-floating in the bloodstream emboli 7. Emboli may become lodges in smaller blood vessels 8. Smallest blood vessels in the human body are a.i.1.a.i.1. Coronary blood vessels of the hear
13 Organic: Lipids: Coronary Artery Stent 1. Coronary heart disease (CHD) also known as coronary artery disease (CAD) 2. The #1 killer of both men and women in the United States 3. CHD occurs if plaque builds up in the coronary arteries, which supply oxygen-rich blood to the myocardium in the heart wall
14 Organic: Lipids: Phospholipids 1. Each phospholipid is composed of a glycerol backbone but with… a. 2 free fatty acid chains attached a.i. 2 free fatty acid chains attached non polar and are referred to the “nonpolar tails” b. 1 phosphorous containing group attached to the glycerol in the opposite direction b.i. Phosphorous containing group
