Front

What is a polypeptide?

Back

A polypeptide is a chain of amino acids linked together by peptide bonds.

Front

What is a protein?

Back

A protein is a complex, three-dimensional structure made up of one or more polypeptide chains.

Front

How are proteins composed?

Back

Proteins can be composed of one or more polypeptide chains.

Front

What happens in a protein composed of only one polypeptide chain?

Back

The amino acids interact with each other, folding the chain into a functional protein.

Front

What happens in proteins composed of more than one polypeptide?

Back

The polypeptide chains can interact with each other, contributing to the overall structure of the protein.

Front

Name some examples of proteins.

Back

Examples of proteins include Lysozyme, Alpha-neurotoxins, Glucagon, Myoglobin, Beta-endorphin, Alpha amylase, Titin, Haemoglobin, Keratin, Lipase, and Histones.
