B.3.4 List the major functions of carbohydrates in the human body

B.3.5 Compare the structural properties of starch and cellulose, and explain why humans can digest starch but not cellulose

B.3.6 State what is meant by the term dietary fibre

B.3.7 Describe the importance of a diet high in a dietary fibre

Option B2: Proteins

B.2.1 Draw the general formula of 2-amino acids

B.2.2 Describe the characteristic properties of 2-amino acids

B.2.3 Describe the condensation reaction of 2-amino acids to form polypepetides

B.2.4 Describe and explain the primary, secondary (a-helix and b-pleated sheets), tertiary and quaternary structure of proteins

B.2.5 Explain how proteins can be analysed by chromatography and electrophoresis

B.2.6 List the major functions of proteins in the body.

Option B1: Energy

B.1.1 Calculate the energy value of a food from enthalpy of combustion data

Option B: Human biochemistry

Option B of the IB SL Chemistry syllabus is the Human biochemistry. IBO recommends to spend 15 hours on the topic.

This topic has an additional 6 sub-chapters: "Energy", "Proteins", "Carbohydrates", "Lipids", "Macronutrients and micronutrients" and "Hormones". Each are separated with numerical values in order of mentioned.

These are all SL option syllabus statements, it is recommended to bring a Casio Graphical Calculator instead of Texas.
