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.
Amino acids are the basic unit of proteins. Amino acids linked together by a peptide bond forms a chain of amino acids called a polypeptide. When the amino acids from different parts of the chain interact with each other and form hydrogen bonds, the polypeptide chain takes on a unique shape, forming a protein.
Three or more amino acids are called peptides. Peptides can vary in length, with short peptides consisting of just a few amino acids, while longer peptides can be composed of dozens or even hundreds of amino acids.
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.
Oligopeptides are composed of 2 to 20 amino acids. They are shorter than polypeptides, which typically consist of more than 20 amino acids.
The chemical bond adjacent amino acids is called a peptide bond. It forms between the carboxyl group of one amino acid and the amino group of another, resulting in a bond that links the amino acids together in a protein chain.
The first amino acid in a growing polypeptide chain is usually methionine when translation initiates in eukaryotes, and formylmethionine in prokaryotes. Therefore, there will be one amino acid in the first position of every growing polypeptide chain.
The branched amino acids is used by the organism in protein where the polypeptide chain should be branched, other than that i think they're more or less just involved in transamination reaction and aminoacid-biosynthesis
