Task 1
A, Describe what is meant by the primary and secondary structures of proteins (P3):

Primary Structure of Proteins

The primary structure is the sequence of amino acids that make up a polypeptide chain. 20
different amino acids are found in proteins. The exact order of the amino acids in a specific
protein is the primary sequence for that protein.
They all made out of amino acids, this which are based out of genetic information.

Primary Structure: The unique sequence of amino acids that makes up a protein or
polypeptide chain.

Secondary Structure of Proteins

Protein secondary structure refers to regular, repeated patterns of folding of the protein
backbone. The two most common folding patterns are the alpha helix and the beta sheet.

Secondary Structure: The way in which the primary structure of a polypeptide chain folds.
