Proteins are still defined as polymers even though they aren't combined of constant repeating sequence of monomers. Duluth has an argument that they aren't polymers, but I believe he is wrong. Proteins are made up of amino acids of which there are 20 different types (at least in humans). A protein, or more correctly a polypeptide, is made up of a chain of these amino acids. Even if the order of amino acids is completely random (which it's not but thats a case with genetics) and there are no repeating sequences in the chain, it's still defined as a polymer. I believe cloudprincess is right in relation to proteins.
As it's already been said, starch is made up of thousands of monomers of glucose liked together to make a polymer.

Proteins are not polymers. Starch is a polymer because it is a repeating chain of glucose molecules.
With a polymer, you can cut out a chunk of any length at any postion, and the patter of repeating units will be the same. With a protein, this is not the case since there are different amino acids that are not arranged in a specific repeating patter. The only way you could call a protein a polymer is if you ignore the side chains and focus only on the "back bone" of the protein, which is a repeating amino-carboxylate chain.

Polymers are is a repeated chain of monomers. Groups MONOsaccarides (key word mono meaning one) put together make up starch and other carbohydrates. Proteins are made of amino acids are monomers that come together to form a polymer, protein.
Polymers can repeat endlessdaly. In comparison, fats are made up of one gycerol and 3 fatty acids, which isn't the same as the endlessly repetiiton of one monomer.

Polymers are components whose molecules have severe molar hundreds and are composed of a huge variety of repeating instruments. There are the two of course happening and guy made polymers. between of course happening polymers are proteins, starches, cellulose, and latex. guy made polymers are produced commercially on an exceedingly great scale and have a huge selection of properties and makes use of. The components usually pronounced as plastics are all guy made polymers.

your use of the english language is ridiculous, a polymer is an adhesive. if you have ever cooked rice which is full of starch you would it sticks together
