HKDSE Biology - Biomolecules (Carbohydrate and Lipid)
Compulsory Part I Cells and Molecules of Life
Relate the significance of biomolecules (carbohydrate and lipid) to life.
Biomolecules are elementary building blocks exist in organism and they assist the vital biological process for life.
significance of carbohydrates and lipid 👇🏻
Carbohydrate with the formula of Cx(H2O)y and it can be classified into simple carbohydrate (monosaccharides) and complex carbohydrates (disaccharides and polysaccharides).
👆🏻These are the example of monosaccharides - glucose, fructose and galactose.
👆🏻These are the example of disaccharides - sucrose, lactose and maltose.
👆🏻This is the example of polysaccharides - starch.
Lipid is a non-polar and hydrophobic organic compound that mainly consist of carbon, hydrogen and oxygen.
Lipid can be classified into triglycerides, phospholipids and steroids.
👆🏻This is the structure of triglycerides.
👆🏻This is the structure of phospholipid.
👆🏻These are the structure and example of steroid.
In HKDSE Biology examination, you will be asked question on why carbohydrates and lipids are important towards life ❗️ ❕
That's the end of this topic 👏🏻
