Lipids Elements Carbon Hydrogen Oxygen Look familiar Is
Lipids Elements • Carbon • Hydrogen • Oxygen • Look familiar? • Is this an organic compound?
fatty acids When 3 fatty acids are attached to a glycerol = triglyceride
Lipids 3 varieties of lipids are • Fats- solid at Room Temp-butter • Oils- liquid at Room Temp – peanut oil • Waxes - coating on leaves, honey combs The polymer name is for lipids is lipids
Waxes in plants • Used for coating on leaves to decrease water loss
Plant oils • Stored for future energy in nuts, seeds for growth • We use in cooking • We use for fossil fuel alternatives
Monomers • That’s a lot of energy stored as carbon hydrogen & oxygen!
Lipids are stored in animals in the form of fat • • Used for energy Warmth(insulate) Cushions Cell membranes Insulates nerves Absorbs vitamins hormones
In saturated fat each C atom is joined to another C atom by a single bond. The fatty acid has the maximum # of H atoms • Found in red meats, butter, ice cream, cheese • Leads to clogged arteries
Unsaturated fats not all carbon bond sites filled There is at least 1 carbon to carbon double bond. • Found in plant products • A healthy kind of lipid
Foods high in lipids • • • Butter, meat Olive oil, corn oil Veggies Nuts Your body cannot make all of the fatty acids it needs so you need to EAT them(found in plant oils)
Lipids __ __ __ Product Of photosynthesis ______ __ Proteins __ __ __ Nucleic Acids __ __ __ • Plants use photosynthesis to make monomers of carbohydrates known as sugar, or monosaccharides. • When other elements from the soil (nitrogen, phosphates, and sulfur are added plants can make all the organic macromolecules we have been studying. • These macromolecules are then passed through the food chain. Polymers are digested into monomers to make polymers for the organism that ate the food.
Lipids can be tested for using a brown paper bag.
You can influence the condition of your blood vessels with a healthy diet and exercise.
The choice is yours IMPROVE vs. IGNORE
