IB Biology Protein

The difference between tertiary and quartenary structure is:

• Tertiary structure has double bond whereas quartenary structure does not have double bond

• Tertiary structure consists of one polypeptide chain whereas quartenary structure consists of more than one polypeptide chains

• Tertiary structure is fibrous whereas quartenary structure is globular

• Tertiary structure is water-soluble whereas quartenary structure is lipid soluble

The repeating units of protein are

• Amino acids

• Glucose

• Fatty acid

• Peptides
