Biomolecules – Solutions
1. What are macromolecules? Give examples.
A macromolecule is a very large molecule and mostly created by some form of polymerisation. In biochemistry, the term may be applied to the four conventional biopolymers – nucleic acids, proteins, carbohydrates and lipids – as well as non-polymeric molecules with a large molecular mass such as macrocycles. It usually constitutes part of intercellular fluids and remains in a colloidal state.
- Illustrate a glycosidic, peptide and a phosphor-diester bond.
A glycosidic bond is formed between a molecule derived from a saccharide and the hydroxyl group of some organic compound such as an alcohol or any other saccharide.
A peptide bond is formed between two molecules when the carboxyl group of one molecule reacts with the amine group of the other, thereby releasing a molecule of water.
