- Protein structure
- They're polymers
- Amino acids are the monomers
- A dipeptide is formed when two amino acids are joined
- A polypeptide is formed when two or more amino acids join
- Proteins are made up of one or more polypeptides

- Proteins are made up of one or more polypeptides
- A polypeptide is formed when two or more amino acids join
- Amino acids have different variable groups (R)
- They have the same general structure
- A carboxyl group (-COOH)
- They have the same general structure
- Amino acids all contain carbon, oxygen, hydrogen and nitrogen.

- There's four structural levels to protein
- Quaternary structure
- Some proteins are made of several different polypeptide chains held together by bonds
- An example is haemoglobin which is made of four polypeptide chains bonded together
- For proteins made from more than one polypeptide chain, the quaternary structure is the proteins final 3D structure
- An example is haemoglobin which is made of four polypeptide chains bonded together
- Some proteins are made of several different polypeptide chains held together by bonds
- Quaternary structure
- Globular Proteins
- Examples of globular proteins
- Amylase
- An enzyme that catalyses the breakdown of starch in the digestive system
- Its secondary structure contains both alpha-helix and beta-pleated sheet sections
- Amylase
- Examples of globular proteins
- Fibrous proteins
- Tough and Rope-Shaped
- Collagen
- Found in animal connective tissues such as bone skin and muscle
- Very strong molecule, minerals can bind to it to increase rigidity e.g. bone
- Collagen
- Tough and Rope-Shaped
- They're polymers

- An amino group (-NH2)
- Which are attached to a carbon atom
