Molecules to metabolism
Understandings:
• Molecular biology explains living processes in terms of the chemical substances involved.
• Carbon atoms can form four covalent bonds allowing a diversity of stable compounds to exist.
• Life is based on carbon compounds including carbohydrates, lipids, proteins and nucleic acids.
• Metabolism is the web of all the enzyme-catalysed reactions in a cell or organism.
• Anabolism is the synthesis of complex molecules from simpler molecules including the formation of macromolecules from monomers by condensation reactions.
• Catabolism is the breakdown of complex molecules into simpler molecules including the hydrolysis of macromolecules into monomers.

Skill: Drawing molecular diagrams of glucose, ribose, a saturated fatty acid and a generalized amino acid.
Skill: Identification of biochemicals such as sugars, lipids or amino acids from molecular diagrams.
Skill: Identification of biochemicals such as sugars, lipids or amino acids from molecular diagrams.
Guidance:
• Only the ring forms of D-ribose, alpha–D-glucose and beta-D-glucose are expected in drawings.
• Sugars include monosaccharides and disaccharides.
• Only one saturated fat is expected and its specific name is not necessary.
• The variable radical of amino acids can be shown as R. The structure of individual R-groups does not need to be memorized.
• Be able to recognize from molecular diagrams that triglycerides, phospholipids and steroids are lipids. Drawings of steroids are not expected.
• Proteins or parts of polypeptides should be recognized from molecular diagrams showing amino acids linked by peptide bonds.
