List of Basic Biochemistry Topics

Biochemistry is the branch of science that explores the chemical processes within and related to living organisms. It is a laboratory-based science that brings together biology and chemistry, using chemical knowledge and techniques to solve biological problems. This article provides a list of fundamental topics in biochemistry, which serve as the foundation for understanding the complex interactions and processes that sustain life.

Amino Acids

Amino acids are the building blocks of proteins. They play critical roles in enzyme catalysis, neurotransmitter functions, and as precursors for the synthesis of molecules such as hormones and neurotransmitters.

Proteins

Proteins are large biomolecules consisting of one or more long chains of amino acid residues. They perform a vast array of functions within organisms, including catalyzing metabolic reactions (enzymes), DNA replication, responding to stimuli, and transporting molecules from one location to another.

Enzymes

Enzymes are biocatalysts that speed up chemical reactions in cells. They are crucial for metabolism, as they allow organisms to drive desirable reactions that require energy.

Carbohydrates

Carbohydrates are essential for energy storage and transport (glucose), as well as for maintaining the structural integrity of cells (cellulose in plants, chitin in animals).

Lipids

Lipids are a group of naturally occurring molecules that include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E, and K), monoglycerides, diglycerides, triglycerides, and phospholipids. They serve as structural components of cell membranes, energy storage molecules, and signaling molecules.

Nucleic Acids

Nucleic acids, including DNA and RNA, are biopolymers essential for all known forms of life. They carry genetic information and are involved in the synthesis of proteins.

Metabolism

Metabolism refers to the chemical reactions in living organisms that maintain life. It can be divided into two categories: catabolism, the breakdown of molecules to obtain energy, and anabolism, the synthesis of all compounds needed by the cells.

Vitamins and Minerals

Vitamins and minerals are essential nutrients that the body needs in small amounts to work properly and stay healthy. They are involved in numerous biochemical processes, including enzyme function, metabolism, and cellular signaling.

Bioenergetics

Bioenergetics is the study of the transformation of energy in living organisms. It encompasses the cellular processes of energy production, consumption, and conversion.

Molecular Genetics

Molecular genetics is the field of biology that studies the structure and function of genes at a molecular level. It focuses on the flow of genetic information between DNA, RNA, and proteins.

Signal Transduction

Signal transduction involves the transmission of molecular signals from a cell's exterior to its interior. Signals received by receptors can stimulate cellular responses such as gene expression, cell growth, or apoptosis.

Photosynthesis

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. It is a critical biochemical process for life on Earth, providing the oxygen we breathe and the basis of the food chain.

Cellular Respiration

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
