Peptides (from the Greek πεπτίδια, "small digestibles") are short polymers formed from the linking, in a defined order, of α-amino acids. The link between one amino acid residue and the next is known as an amide bond or a peptide bond. Proteins are polypeptide molecules (or consist of multiple polypeptide subunits). The distinction is that peptides are short and polypeptides/proteins are long.

Many amino acids are joined together by peptide bonds to form polypeptides.


Are polypeptides made of polysaccharides?

No. Polypeptides and polysaccharides are two different types of macromolecules. The first class is commonly called "proteins" and the second is commonly called "sugars." Both are polymers - molecules that are composed of smaller subunits called monomers. Polypeptides ― or proteins ― are composed of monomers called amino acids. In contrast, polysaccharides are composed of monomers called monosaccharides.


what are polymers made of amino acids called?

Polymers made of amino acids are called polypeptides or proteins. Amino acids are the building blocks of proteins, and they are linked together through peptide bonds to form long chains known as polypeptides. These polypeptides can then fold into specific shapes to carry out various functions in the body.

Is a polypeptide a lipid?

No, polypeptides are not lipids. Polypeptides are large molecules also called proteins; lipids tend to be relatively small molecules with an "ionic" end and a "greasy" end.


When many polypeptides are linked together it is called a?

When many polypeptides are linked together, it is called a protein. Proteins are macromolecules composed of one or more polypeptide chains that fold into specific three-dimensional structures, enabling them to perform various biological functions. The sequence and arrangement of amino acids in the polypeptides determine the protein's properties and activities.
