Proteins

Proteins:

What are proteins made from?

• Proteins are polymers, large chains of monomers. 
• The monomers of proteins are amino acids. 
• A dipeptide = 2 Amino Acids
• A polypeptide = 2+ Amino Acids 
• Proteins are made of one or more polypeptides. 

Amino Acid Structure: 

• Carboxyl group (-COOH), Amino Group (-NH2), R Group

• Amino Acids are linked together by condensation reactions to form dipeptides and polypeptides. A molecule of water is released during the reaction.
• The bonds formed are called peptide bonds. 
• This bond is between the amino group of one and the carboxyl group of another. 
• Hydrolysis reactions break the peptide bond.

• Sequence of amino acids in a polypeptide chain held together by…
