identify the structures and functions of biomolecules (100)
structure and function: carbohydrates
structure and function: lipids
structure and function: proteins
structure and function: nucleic acids

Explanation:

1. Lipids like phospholipids have a hydrophilic head and hydrophobic tails. Carbohydrates do not have this structure.
2. Triglycerides, a type of lipid, consist of three fatty - acid molecules and one glycerol molecule. Carbohydrates have a different composition.
3. Some carbohydrates, like cellulose, have long chains of glucose arranged in parallel rows. Lipids do not have this characteristic glucose - chain structure.

Answer:

	Lipid	Carbohydrate
May contain three fatty acid molecules and one glycerol molecule	Yes	No
May have long chains of glucose arranged in parallel rows	No	Yes
