Proteins

Proteins

• Contain Ozygen, Hydrogen, Carbion and Nitrogen
• Large compunds made up up amino acids 

• There are loads of different Proteins and the differ by the specific sequence of the amino acids
• All amino acids have the same basic structure; have a carboxyl group an amino group and a different R group 

Formation of a Peptide Bond

• Proteins built from linear sequence of amino acids
• The amino group of one amino acid react with the carboxyl group of another with the elimination of water (condensation reaction)
• The bond between the two amino acids is called a Peptide Bond
• A dipeptide is formed

Protein Structure

Primary 

• A sequence of amino acids in a polypeptide chain
