Question

1. what is the primary function of lipids?
2. why do lipids technically not have true monomer?
3. summarize lipids in the table below.

type	composition	functions
phospholipids
steroids
waxes

Explanation:

1. Lipids primarily function as energy - storage molecules and for insulation. They also protect vital organs.
2. Lipids do not have true monomers because they are not made up of identical repeating subunits like polymers. For example, triglycerides are composed of glycerol and fatty acids which are different types of molecules.

9.

Type	Composition	Functions
Phospholipids	Glycerol, two fatty acids, and a phosphate - containing group	Major component of cell membranes
Steroids	Four - ring carbon structure	Component of cell membranes, hormones (e.g., cholesterol, cortisol)
Waxes	Long - chain fatty acids bonded to long - chain alcohols and other hydrocarbons	Waterproofing in plants and some organisms, structure in honeycombs (in bees), rigidity in insect exoskeletons

Answer:

1. Energy - storage, insulation, protection of vital organs
2. Composed of different types of molecules, not identical repeating subunits
3. See table above
