Macromolecules are large molecules formed by polymerizing smaller subunits, including nucleic acids, proteins, and carbohydrates in biochemistry. Micromolecules are relatively small molecules like monomers, water, minerals, and vitamins. The document discusses various foods like oranges, pulses, milk, and wood that are good sources of important macromolecules and micromolecules that perform essential functions in the body.

2. Macromolecule
A macromolecule is a very large molecule
commonly created by polymerization of smaller
subunits. In biochemistry, macromolecules are
the three conventional biopolymers (nucleic
acids, proteins, and carbohydrates), as well as
non-polymeric molecules with large molecular
mass such as lipids.

3. Micromolecule
• A molecule of relatively low molecular weight.
Monomers are considered a micromolecule
that can be linked together to form polymer.
• Inorganic compounds like water and minerals
are examples of micromolecules.
• Vitamin are also micromolecule.

4. Orange
• excellent source of vitamin C
• vitamin A,
• good source of B-complex vitamins
• contains a very good amount of minerals like potassium and
calcium.
Role-: Potassium is an important component of cell and body
fluids that helps control heart rate and blood pressure
through countering sodium actions.

5. Wood
Rich in cellulose
Cellulose is a straight chain
polymer of D-glucose.
It is a Polysaccharide i.e
Macromolecule

6. Pulses
• A good source of proteins, they are a staple
food in many parts of the world.

7. Function
• Repair and Maintenance
• Energy
• Hormones
Insulin, a small protein, is an example of a
hormone that regulates blood sugar.
• Enzymes
• Transportation and Storage of Molecules
For example, hemoglobin is a protein that
transports oxygen throughout the body

8. Other source of protein
• Eggs
• Meat
• Cheese

9. Milk
Protein: Helps build and repair body tissues, including
muscles and bones.
Vitamin A: Aids bone and tooth development. Also aids in
the maintenance of night vision and healthy skin.
Vitamin B12: Aids in red blood cell formation.

10. FATS- good source of fats.
Vitamin D: Enhances calcium and phosphorus
absorption, on which strong bones and teeth
depend.
Calcium: Aids in the formation and maintenance
of strong bones and healthy teeth.

11. Magnesium: Factor in bone and teeth health,
conversion of food into energy and tissue formation.
Phosphorus: Factor in the formation and maintenance
of strong bones and healthy teeth.
Potassium: Aids in the correct functioning of nerves
and muscles.
Zinc: Factor in tissue formation, including bones
