The Chemical makeup of Natural Rubber is a polymer of isoprene molecules, specifically cis-polyisoprene, the main constituent.

Eg: Latex is the polymer cis-1, 4-polyisoprene" with a molecular weight of 100, 000 to 1, 000, 000 daltons. Typically, a small percentage (up to 5% of dry mass) of other materials, such as proteins, fatty acids, resins, and inorganic materials (salts) are found in natural rubber.

Actually, none of the options is right, but as Rubber contains, however, small quantity of Protein, it can be chosen as an answer.

The condition now commonly known as "Latex allergy" is caused by the proteins produced from the rubber tree (Hevea brasiliensis) that are still present in the products manufactured from natural rubber latex. This allergy is not only caused by the proteins, but also by the chemicals and/or residues thereof.

Cellulose and starch are not made up of amino acids. Proteins are, therefore starch or cellulose can't be protein and none of the other cannot be the answer. So the answer would automatically be [A] natural rubber.

Protein is a huge structure containing more than 100 peptide (amide) bonds and all the 20 essential and non essential amino acids few of which are glycine, alanine, valine, leucine, isoleucine, etc. I think N.O.T.

I think D is correct because starch is a complex carbohydrate, not a protein cellulose: is a polysaccharide, not a protein.

Natural rubber: polyisoprene not protein.

Natural rubber is a protein as it's main constituent{monomer}IS ISOPRENE.While for synthetic rubber it is neoprene.
Hope it was helpful!

Cellulose&starch are made up of amino acids.

So I think natural rubber is correct.

What I know its a polymer not a protein because protein is made up of amino acid.

Structural unit of the protein is amino acids so answer is none of these.

Protein is an important part of the protective layer of rubber particles.
