| Bile | produced by the liver and stored in the gallbladder. the hormone cholecystokinin signals the gallbladder to release bile into the duodenum. Bile acts as an emulsifier, breaking fats into smaller droplets to help enzymes digest them more effectively. |
| Cholesterol | Synthesized only in animal tissues. Normal component of bile and gallstones. Synthesized in the liver. |
| Chylomicron | Functions to allow the absorption of fat in to the lymphatic circulatory systenm before entry into blood circulation. A lipoprotein formed in the intestinal cell that is composed of triglycerides, cholesterol, phospholipids, and protein. |
| Emulsifier | A substance that helps mix fats and water into a stable mixture that holds fat droplets in water. |
| Fatty Acids | The major structural component of fats. |
| Glycerides | The chemical name for fats. Fats that are formed from a glycerol base with one, two, or three fatty acids attached. These are the principal components of adipose tissue found in animal fats, and vegetable oils and fats. |
| Glycolipid | A lipid with a carbohydrate attached. |
| Triglycerides | The chemical name for fats in the body or in food; three fatty acids attached to a glycerol base. |
| Alpha-Linolenic Acid | An essential fatty acid with 18 carbon atoms and 3 double bonds; found in soybean, canola, and flaxseed oil. |
| Linoleic Acid | Essential fatty acid that has 18 carbon atoms and 2 double bonds; found in vegetable oils |
| Micelles | free fattyacids, monoglycerides, bile salts; aid in the absorption of fats and fatsolb vit during digestion; structure of the outside is (hydrophilic) heads facing outward and the inside (hydrophobic) tails facing inward holding on to fat molecules. |
| Saturated | The state of being filled; state of fatty acids being filled in all their available carbon bonds with hydrogen. |
| Dyslipidemia | A medical condition where a person has abnormal lipid profile such as high cholesterol |
| Atherosclerosis | Plaque build up |
| endothelium | The inner lining of arteries can be damaged by factors such as high blood pressure, smoking, or diabetes. |
| Plaque | Over time, the fatty streak becomes a plaque. mix of chlesterol, immune cells and cellular debris. |
| LDL | Bad cholesterol, builds up in arteries. |
| HDL | Carries LDL away from arteries and to liver. You want this to be higher |
| Dyslipidema | Abnormal amnt of liids (triglyceride or cholesterol) in the blood that increase cardiovascular risks. |
| Atherosclerosis | The underlying pathology of heart disease. |
