2. What Is Biochemistry?
Biochemistry is the study of the chemistry of living things. This includes organic molecules and their chemical reactions.

3. What Is Biochemistry Used For?
Biochemistry is used to learn about the biological processes which take place in cells and organisms.
Biochemistry may be used to study the properties of biological molecules, for a variety of purposes:
biochemist may study the characteristics of the keratin in hair so that a shampoo may be developed that enhances curliness or softness.

4. What Is Biochemistry Used For?
biochemist may use a certain lipid as a food additive.
3. biochemist might find a substitute for a usual biomolecule. For example, biochemists help to develop artificial sweeteners.

5. What Types of Molecules Do Biochemists Study?
The principal types of biological molecules, or biomolecules are:
Carbohydrates (Glucose, Lactose, Starch, etc.).
Lipids (Fatty Acids, Glycerol's, TAG’S ).
Proteins (Amino Acids).
nucleic acids (DNA, RNA).

6. How do we study those molecules ?
The Biochemical tests and experiments can be classified mainly into:
Qualitative study tests:
Color.
Precipitation.
Liquidity and/or solidity.
Evaporation.

7. How do we study those molecules ?
2. Quantitative study tests:
PH measurements.
Buffers effects.
Specificity (e.g. enzymes).

8. Basic SI Units

9. Commonly Used Metric Prefixes
