Name Date Period Which category of carbon-based molecules includes sugars and starches? unsaturated fatty acids Phospholipids Proteins Carbohydrates Which elements does a carbohydrate contain? carbon, hydrogen and nitrogen carbon and hydrogen carbon, hydrogen and oxygen carbon, oxygen and nitrogen

Lipids

Lipids Monomer: fatty acid Long chain of hydrocarbons

Lipids Polymer: triglyceride head tail

Lipids head: polar and hydrophilic tail: nonpolar and hydrophobic

Lipids head: polar and hydrophilic likes water! tail: nonpolar and hydrophobic doesn’t like water!

Saturated lipids are straight Unsaturated lipids are bent

Saturated lipids are straight Unsaturated lipids are bent

Lipids provide long-term energy Found in: Fats Oils Waxes And lipids provide insulation

Lipids head: polar and hydrophilic likes water! tail: nonpolar and hydrophobic doesn’t like water!

Where does the energy come from in a lipid? Lipids Question! Where does the energy come from in a lipid? fatty acid monosaccharide

Lipids Question! Why does a bear need a bunch of fat on his body to make it through winter? fatty acid monosaccharide

Lipids provide long-term energy Found in: Fats Oils Waxes And lipids provide insulation
