The basic structure and functions of glycogen, starch and cellulose
Glycogen, starch, and cellulose are all large carbohydrates made from glucose. Their different structures make them suited to very different jobs — energy storage or physical support.
Real World
Cotton fabric is almost pure cellulose; the tensile strength that makes a cotton T-shirt hard to tear comes from the parallel cellulose microfibrils cross-linked by hydrogen bonds.
Exam Focus
Use a comparison table approach: for each molecule state glucose type, bond type, branching, and function — this prevents omissions under exam pressure.
Evaluation Scaffold
A four-step framework for high-quality evaluation. Use this for 'assess', 'evaluate', and 'to what extent' questions.
