Yes. Remember that when 2 atoms of the same or different elements combine, it forms a molecule. 2 hydrogen atoms + 1 Oxygen atom = 1 molecule of H20(water). The same holds true for proteins, proteins are composed of amino acids, which are in turn composed of different molecules, which are also composed of different atoms.

Polypeptides are chains of amino acids.
No, Polypeptides are chains of amino acids and Proteins
Aminopeptidase & carboxypeptidase
There are four atoms of iron in a molecule of hemoglobin. Each iron atom is attached to a porphyrin, forming a heme group. Each heme group is attached to a polypeptide chain. There are two alpha and two beta polypeptides. So a hemoglobin molecule has four heme groups, and four polypeptides.
A dipeptide is a molecule consisting of two amino acids joined by a single peptide bond. Dipeptides are produced from polypeptides by the action of the hydrolase enzyme dipeptidyl peptidase
The chemical reaction used to synthesize macromolecules like polypeptides and starch is called dehydration synthesis or condensation reaction. This reaction involves joining monomers together by removing a water molecule to form a covalent bond between them.
Amino acids are assembled in ribosomes. Polypeptides are the out products.
Ribosomes are the cellular structures responsible for assembling amino acids into polypeptides during the process of protein synthesis. Ribosomes are composed of rRNA and proteins and can be found in the cytoplasm or on the endoplasmic reticulum.
peptones and peptides together form long chains in the form of polypeptides.
No. Polypeptides are **not** carbohydrates. A polypeptide is a chain of amino acids linked together by peptide bonds. One or more polypeptides fold into specific shapes to form proteins, which perform many important functions in the body, such as building tissues, acting as enzymes, and supporting the immune system. Carbohydrates, on the other hand, are made of sugar molecules (such as glucose) and are the body's primary source of energy. They have a different chemical structure and function than polypeptides. In short: **Polypeptides** → made of amino acids; form proteins. **Carbohydrates** → made of sugars; mainly provide energy. Although both are essential biomolecules, they belong to different classes and serve different roles in living organisms.
