Study Notes

Major Biological Macromolecules

The four major biological macromolecules are carbohydrates, proteins, lipids, and nucleic acids.

Branches of Modern Biochemistry

The two branches of modern biochemistry are Descriptive Biochemistry and Dynamic Biochemistry.
Descriptive Biochemistry focuses on the structure and function of biomolecules.
Dynamic Biochemistry deals with the chemical reactions and processes that occur within living organisms.

Emerged Disciplines

Disciplines that have emerged from biochemistry include molecular biology, genetic engineering, and biomedical engineering.

Contribution to Drug Development

Biochemists contribute to the development of new drugs to treat diseases by understanding the chemical basis of biological processes and identifying potential targets for therapy.

Carbohydrates

The primary foodstuff in most organisms is carbohydrates, which play a central role in energy production and storage.
Carbohydrates are classified into three main classes: monosaccharides, disaccharides, and polysaccharides.
Examples of carbohydrates with a structural or storage role include cellulose, chitin, and starch.

History of Biochemistry

The term 'Biochemistry' was first described by Friedrich Wöhler in 1838.

Objectives of Studying Biochemistry

The major objectives of studying biochemistry are to understand the chemical basis of life, to understand the mechanisms of biological processes, and to develop new treatments and therapies for diseases.
The objectives of studying biochemistry can be related to daily life by understanding how biochemistry affects our health, nutrition, and environment.
