Detailed explanation-1: -Figure 11.4 Peptides and Proteins are macromolecules built from long chains of amino acids joined together through amide linkages. The identity and function of a peptide or a protein is determined by the primary sequence of amino acids within its structure.

Detailed explanation-2: -The four major macromolecules are Proteins, carbohydrates, lipids, and nucleic acids. The function of macromolecules are: Provide structural support.

Detailed explanation-3: -Amino acids are commonly found in the protein macromolecule. We can consider amino acids as the basic unit of protein where the side chain or R-groups of amino acids are mainly involved in stabilizing and properties of the structure.

Detailed explanation-4: -Proteins are made up of hundreds or thousands of smaller units called amino acids, which are attached to one another in long chains. There are 20 different types of amino acids that can be combined to make a protein.
