biological macromolecule	function	monomer	examples
lipids
proteins

Explanation:

For Lipids:

Step1: Recall Lipid Functions

Lipids function in long - term energy storage, as components of cell membranes (phospholipids), as signaling molecules (steroids like hormones), and for insulation/protection.

Step2: Recall Lipid Monomers

Lipids do not have a single monomer in the same way as other macromolecules. Triglycerides are made of glycerol and fatty acids; phospholipids have glycerol, fatty acids, and a phosphate - containing group; steroids are based on a cholesterol - like structure. But if we consider the main building blocks for many lipids, for triglycerides, the "monomers" (subunits) are glycerol and fatty acids.

Step3: Recall Lipid Examples

Examples of lipids include triglycerides (fats and oils), phospholipids (cell membrane components), steroids (cholesterol, estrogen, testosterone), waxes (plant cuticles, bee wax).

Step1: Recall Protein Functions

Proteins have diverse functions: enzymatic (catalyze reactions), structural (e.g., collagen, keratin), transport (e.g., hemoglobin), defensive (e.g., antibodies), regulatory (e.g., hormones like insulin), and motor (e.g., actin, myosin).

Step2: Recall Protein Monomers

The monomer of proteins is amino acids. There are 20 different amino acids that can be linked together by peptide bonds.

Step3: Recall Protein Examples

Examples of proteins include enzymes (e.g., amylase, catalase), structural proteins (collagen, keratin), transport proteins (hemoglobin, transferrin), antibodies (immunoglobulins), hormones (insulin, growth hormone), and motor proteins (actin, myosin).

Answer:

(for Lipids row):

• Function: Long - term energy storage; Component of cell membranes; Signaling (hormones); Insulation/protection
• Monomer: No single monomer (triglycerides: glycerol + fatty acids; phospholipids: glycerol + fatty acids + phosphate - containing group; steroids: based on cholesterol - like structure)
• Examples: Triglycerides (fats, oils); Phospholipids; Steroids (cholesterol, estrogen, testosterone); Waxes
