Which organic macromolecules are composed of chains of amino acids that join to form the structural components of organisms.
A
Carbohydrates
B
Proteins
C
Amino Acids
D
Lipids
Explanation: 

Detailed explanation-1: -Figure 11.4 Peptides and Proteins are macromolecules built from long chains of amino acids joined together through amide linkages.

Detailed explanation-2: -Proteins are built as chains of amino acids, which then fold into unique three-dimensional shapes. Bonding within protein molecules helps stabilize their structure, and the final folded forms of proteins are well-adapted for their functions.

Detailed explanation-3: -A macromolecule made of amino acids is a protein.

Detailed explanation-4: -Answer and Explanation: The macromolecules made of amino acids are: (a) proteins. Proteins are folded polypeptides that are composed of amino acid monomers covalently linked together by peptide bonds.

Detailed explanation-5: -A protein is an organic molecule composed of amino acids linked by peptide bonds.
