YES AND NO.

Firstly: A polyepeptide is a protein, constructed of many amino acids, coded for by the genetic code. (in triplets).

A cell produces many polypeptides--in other words proteins.__ These proteins (polypeptides) each have a specific purpose/role in the cell.For example, hameoglobin is a polypeptide. Proteins are basically refererd to as polypeptides, as they consist of many amino acids bounded together. POLY= MANY. Of some of the polypeptides (proteins) some are enzymes.

Enzymes catalyse reactions. Their poltpeptide shape--tertiary structure enables them to do this, as they have an active site which binds to the substrate. Each enzyme catalyses a specific substate.

Anyway, i think that's all you need to know.

Are enzymes composed of polypeptides?

Because enzymes are proteins. Short proteins are called poypeptides.


What is composed of polysaccharide and polypeptide?

Glycoproteins are composed of polysaccharide chains (carbohydrates) covalently linked to polypeptide chains (proteins). These molecules play important roles in cell signaling, recognition, and structure in living organisms.


Composed of long chains of amino acids?

Proteins are composed of long chains of amino acids that are linked together by peptide bonds. These amino acids can vary in sequence and length, giving each protein its unique structure and function.


What bio molecule is enzymes?

All the enzymes are protein or protein conjugates(with lipids or carbohydrates)


Do all proteins consist of one or more polypeptide chains?

Yes, all proteins are composed of one or more polypeptide chains, which are formed from amino acids. Proteins can be made up of a single polypeptide chain or multiple chains that interact with each other to form a functional protein molecule.


What does chains of amino acids?

polypeptide chains!


How could a change in a polypeptide affect cell activity?

Enzymes are derived from polypeptide chains, enzymes are responsible for adequate cell activity. Therefore, if a polypeptide chain is not properly composed, the enzyme will be dysfunctional, hence leading to a depletion in cell activity.


What are oligomeric enzymes?

Oligomeric enzymes are enzymes composed of multiple subunits that come together to form an active enzyme complex. These subunits can be identical or different, and their arrangement is crucial for the enzyme's function. The oligomeric structure allows for increased stability, regulation, and efficiency of the enzyme.


What is polypeptide chains?

Chains of amino acids are referred to as polypeptides. Proteins are created from one or more of these polypeptide molecules.


What is the entire length of protein called?

The entire length of a protein is referred to as its "polypeptide chain." Proteins are composed of one or more polypeptide chains, which are sequences of amino acids linked by peptide bonds. The specific sequence and length of these chains determine the protein's structure and function.

B) Enzymes are composed of chains of amino acids and are considered to be a type of protein.


Is polypeptide chain a protein?

A polypeptide chain is made up amino acids that form from a peptide bond. The polypeptide chain makes up a protein; therefore, the type of protein is contingent on the number of chains present.
