What is biochemistry and what is the content of biochemistry

The abbreviation of biochemistry is put.

It should be mainly about studying biochemistry, that is, the various chemical reactions that occur in living organisms. For example: chemical reactions in photosynthesis, chemical reactions in respiration.

Sugars, proteins, fats, and reactions in biological systems.

Biology and chemistry are interconnected.

Put the common knowledge into a special system.

It's biochemistry.

What students should learn about biology is the only way you can't be concrete, you can only be abstract.

1. Biochemical composition.

In addition to water and inorganic salts, the organic matter of living cells is mainly composed of carbon atoms combined with hydrogen, oxygen, nitrogen, phosphorus, sulfur, etc., and is divided into two categories: large molecules and small molecules.

The former includes bound proteins, nucleic acids, polysaccharides, and lipids; The latter includes vitamins, hormones, various metabolic intermediates and amino acids, nucleotides, sugars, fatty acids and glycerol required for the synthesis of biological macromolecules. In different organisms, there are also various secondary metabolites, such as terpenes, alkaloids, toxins, antibiotics, etc.

2. Metabolic regulation and control.

Metabolism is made up of anabolism and catabolism. The former is the process by which an organism takes substances from the environment and transforms them into new substances in the body, also known as assimilation; The latter is the process by which the original substance in the organism is transformed into the substance in the environment, also known as alienation. The process of assimilation and alienation consists of a series of intermediate steps.

3. Structure and function.

The diverse functions of biological macromolecules are closely related to their specific structures. The main functions of proteins are catalysis, transport and storage, mechanical support, locomotion, immune protection, information reception and delivery, metabolic regulation, and gene expression. Thanks to the development of structural analysis techniques, one can study their various functions at the molecular level.

The study of the principles of enzyme catalysis is a prominent example of this.

Biochemistry, as the name suggests, is a discipline that studies the chemical processes in living organisms, and is often referred to simply as biochemistry.

It is mainly used to study the structure and function of biological macromolecules such as proteins, sugars, lipids, nucleic acids and other biological macromolecules. For chemical biology, the focus is on using methods in chemical synthesis to answer the relevant problems found in biochemistry.

Biochemistry was introduced around the late 19th and early 20th centuries, but its origins go back much further, and its early history is part of the early history of physiology and chemistry.

Biochemistry is a must be learned in bioengineering, and the main research content of this book roughly includes several aspects, the chemical composition of organisms, the metabolism of substances in organisms, energy conversion, and metabolic regulation, and the information metabolism of organisms.

Biochemistry is the science that studies the chemical composition of living organisms, the various chemical changes that sustain life activities and their interconnections, that is, the science that studies the chemical nature of living activities.

The objects of biochemical research are living organisms, including viruses, archaea, eubacteria, yeasts, fungi, algae, and plants and animals.

The core of biochemistry is metabolism (mastering several major cycles in the human body, such as the metabolism of sugars, the three major carboxylic acid cycles, oxidative phosphorylation, photosynthesis, etc.), of course, the core will also focus on molecular biology, that is, some questions about the expression of gene regulatory proteins. These form the basis for future research, such as rotten diseases (which require the study of genetic and metabolic problems).

The theoretical foundation you need is organic chemistry and basic chemistry, as well as the basic theories in front of the biochemistry textbook. The latter is the knowledge of metabolism and synthesis, which needs the theoretical support of the front.

Biochemistry is the field of science that studies biomolecules and their interactions, metabolic pathways, and biochemical processes such as energy conversion in living systems.

Biochemistry is an interdisciplinary discipline of biology and chemistry that aims to understand and explain the functions and mechanisms of living systems at the molecular level. Biochemistry focuses on the structure, composition, and function of biomolecules, such as proteins, nucleic acids, sugars, and lipids. It studies the processes of synthesis, folding, transport, storage, and degradation of these biomolecules in cells and organisms, and their functions in cell signaling, metabolism regulation, gene expression, and more.

In the field of biochemistry, the contents involved include enzymology, metabolic pathways, etc.

The research methods of biochemistry mainly include the separation and purification of biomolecules, the analysis of their structure and function, and the determination of reaction rates and metabolites. Through these methods, biochemistry researchers can deeply explore the composition and properties of biomolecules, reveal the mechanisms of biochemical processes in living organisms, and provide an important foundation for other fields such as medicine, agriculture, and biotechnology. The study of biochemistry not only helps to reveal the basic principles of life activities, but also provides a theoretical and practical basis for applications such as disease research, bioengineering, and new drug development.

Uses of biochemistry

1. Drug R&D: Biochemistry provides an important foundation for drug R&D. By understanding the structure and function of biomolecules, researchers can design and synthesize drug molecules with specific effects and study their metabolism and mechanisms of action in living organisms.

2. Genetic research: Biochemistry reveals the structure and function of genes, as well as the regulation mechanism of gene expression in cells. This is essential for understanding genetic phenomena, studying the association between genetic mutations and diseases, and conducting research on genetic engineering and genetics.

3. Positive cavity metabolism research: Biochemistry studies biochemical processes such as metabolic pathways and energy conversion are essential for understanding the regulation and interaction of various metabolic pathways in cells. In addition, metabolic research is also of great significance for human health, nutrition, and disease research.

4. Enzyme engineering and biocatalysis: Biochemistry can help optimize and improve the catalytic performance of biological enzymes, so as to improve the efficiency and selectivity of reactions in industrial production, environmental protection and pharmaceuticals.

5. Molecular diagnosis and biomarker research: Biochemistry can identify and detect molecular markers in living organisms, such as proteins and nucleic acids, so as to provide an important basis for medical diagnosis and research.

Biochemistry (also known as physiological chemistry) is the use of chemical and physicochemical methods to study the life phenomena of organisms at the molecular level, that is, to study the molecular structure, chemical changes and physicochemical changes of animal and plant cells and bacterial cells, and to analyze their regulation and organization. The first is the process of material exchange, the decomposition of food, the conversion to chemical energy and the formation of a part of cellular matter. Further research subjects include catalytic agents, enzymes (enzyme science) and molecular information carriers, ribonucleic acid and deoxyribonucleic acid (molecular genetics, genetic engineering, biosurgery).

These studies are of great significance to various fields of biology, chemistry, medicine, physics, and especially biotechnology. There are many ways to learn biochemistry. In some universities, there are independent majors, and in others, biochemistry is a key course in chemistry and biology.

The human biology major is also biochemistry-oriented. In other disciplines such as pharmacology, food technology, nutrition, etc., biochemistry is also a basic major.

The term biochemistry appeared around the late 19th and early 20th centuries, but its origins go back much further, and its early history is part of the early history of physiology and chemistry.

1860 lPasteur proved that fermentation was caused by microorganisms, but he believed that a living yeast was necessary to cause fermentation. In 1897, the Birchner brothers discovered that the cell-free extract of yeast could be fermented, proving that such complex life activities could be carried out without living cells, and finally overturned the "theory of vitality".

Another example is 1828 fWaller synthesized an organic substance urea for the first time in the laboratory, breaking the idea that organic matter can only be produced by living organisms, and dealing a major blow to the "vitalism".
