Common mistakes in Carbohydrates and lipids
Recorded against questions in this topic that are not shown above, so none of these points at an answer you can see on this page.
- Calls any carbohydrate that can be hydrolysed a monosaccharide.
- Chooses a storage carbohydrate or lipid for a structural wall role.
- Assumes energy density increases simply because a molecule contains more oxygen.
- Uses the word polymer without distinguishing storage, structural and lipid architectures.
