proteins
a chain of 25 amino acids can be called a peptide chain ---------------------------------------------------------------------------------- Two or united amino acids form a *dipeptide* Three a *tripeptide* Ten or more a *polypeptide* More than 50 *protine* Therefore a chain of 25 amino acids is a polypeptide :D
A chain of more than 50 amino acids is called a protein. Chains of amino acids in general can be called polypeptides - which refers to the type of bond between the amino acids (a peptide bond).
Proteins are polymers of amino acids. The monomer of proteins is amino acids. Chains of amino acids are polypeptides and are called proteins if there are more than 20 amino acids in the chain.
Proteins are polymers made up of amino acid monomers. Any chain of two or more amino acids is called a peptide. When many amino acids are joined together, the result is called a polypeptide, or a protein.
It is a short chain of amino acids. Theoretically, a protein is a much longer chain of amino acids that can be composed of more than one polypeptide chain.
Even though there are some variants among biochemists, we can consider this: a chain or polymer consisted of 2 to 10 or 12 amino acids is called a peptide. A polymer formed by 12 to 20 or 25 amino acid chain is called a polypeptide. And a polymer of more than 20 or 25 amino acids is called a protein.
monomer = amino acidpolymer = polypeptide (= polypeptide chain)A monomer is one unit in a chain of repeating units. Amino acids are assembled in cells into chains called polypeptides.A protein may consist of just one polypeptide, or more than one. For example, human growth hormone has only one chain, but hemoglobin has four.
No. A protein is defined by its function, as much as its structure. A chain of two amino acids would have no protein-like functions. The smallest known protein is a chain of 20 amino acids, but most have many more, and sometimes consist of multiple chains of amino acids.
it consists of 10- 20 amino acids ....more than this is called polypeptides.....
Proteins
If a polypeptide contains 9 peptide bonds, how many amino acids does it contain?
The official definition of a polypeptide is a linear organic polymer consisting of a large number of amino-acid residues bonded together in a chain, forming part of (or the whole of) a protein molecule. (a string of amino acids)
