BIOL 150 Lecture Notes - Lecture 6: Lipid Bilayer, Unsaturated Hydrocarbon, Safflower
Document Summary
Fats necessary > essential fatty acids we cant make essential fatty acids help with. Trans-fats are made by taking liquid lipids/fats, putting thru a process where you take out double bonds and replace with hydrogen. Trans-double bonds are found in transfers brain maintenance, energy, protects kidneys, help absorb vitamins a,d,e, and k. control inflammation. Cardiovascular disease is leading killer of adults in western societies, saturated fats, and. Cholesterol is a rigid structure that can fit into short and unsaturated hydrocarbon tails (lipid bilayer) lowering its fluidity. Why is our society focused on low-fat diets. Triglycerides = 3 fatty acids, and a glycerol (fats): serve as storage, cushioning/protection, generation of heat. Phospholipids = 2 fatty acids, a glycerol, and a phosphate. Have hydrophobic and hydrophilic ends (amphipathic) crucial component of cell membranes. Bulky structure usually with hydrophobic and hydrophilic ends, can act as hormones (estrogen and testosterone) Lipid micelles - (hydrophilic heads interact with water, hydrophobic tails interact w one another.
