What makes McDonald’s fries taste SOOOO good?. Lipids Lipids are composed of C, H, and O Greater H:O ratio than 2:1 Primary function is energy storage.

Lipids. Lipids are composed of: Carbon Hydrogen Oxygen BUT: Lipid molecules have a larger number of Carbon and Hydrogen and a smaller number of Oxygen.

fructose Monosaccharides Single (simple) sugars; quick energy Contain C, H, and O in 1:2:1 ratio Examples: Glucose C 6 H 12 O 6 Fructose C 6 H 12 O 6.

LIPIDS --- Fats & Oils. LIPIDS include: fats oils cholesterol phospholipids.

Lipids A lipid is any molecule that DOES NOT mix with water. – They are “water fearing” / nonpolar (hydrophobic) Lipids function in: – Energy (E) storage.

LIPIDS

Characteristics of Lipids Composed of Carbon, Hydrogen, and Oxygen Greater than 2:1 ratio of H:O Includes fats, oils, phospholipids, and cholesterol Building blocks are fatty acids and glycerol. Energy storage molecules

Fatty Acid Structure Carboxyl group (COOH) forms the acid. “R” group is a hydrocarbon chain.

Unsaturated Fatty Acid Saturated Fatty Acid

Glycerol
