Who can tell me the specific difference between "life science" and "biochemistry"?

Biological science is a marginal subject. If you want to make achievements here, further study is inevitable.

Biological science is a science that studies the laws of life activities based on experiments. Most universities are in the Academy of Life Sciences, and biotechnology and bioengineering are brother majors. Its specialty covers a wide range, including botany, zoology, microbiology, neurology, physiology, histology, anatomy and so on.

Students in this major mainly study the basic theories and knowledge of biological sciences, and are trained in scientific thinking and scientific experiments in basic research and applied basic research, with good scientific literacy and certain teaching and research capabilities. Cultivate senior specialized personnel in biological sciences who have basic theories, basic knowledge and strong experimental skills and can engage in scientific research, teaching and management in scientific research institutions, universities, enterprises and institutions. The word biochemistry appeared around the end of 19 and the beginning of the 20th century, but its origin can be traced back further, and its early history is a part of the early physiological and chemical history. For example, in the 1980s of 18, A.-L. lavoisier proved that respiration is as oxidation as combustion. Almost at the same time, scientists found that photosynthesis is essentially the reverse process of animal respiration. For example, in 1828, F. Waller synthesized an organic substance-urea for the first time in the laboratory, which broke the view that organic matter can only be produced by organisms and caused a great blow to the theory of vitality. 1860 L. Pasteur proved that fermentation was caused by microorganisms, but he thought that there must be live yeast to cause fermentation. 1897, brothers Bishner discovered that the cell-free extract of yeast can be fermented, which proved that complex life activities such as fermentation can be carried out without living cells, and finally overturned the "vitality theory".

A branch of biology. It is a basic life science that studies the chemical composition, structure and various chemical changes in the process of life activities.

Biochemistry can be divided into animal biochemistry, plant biochemistry, microbial biochemistry, insect biochemistry and so on. If we study different tissues or processes of organisms, they can be divided into muscle biochemistry, neurobiochemistry, immune biochemistry, biomechanics and so on. Because of the different substances studied, it can be divided into protein chemistry, nucleic acid chemistry, enzymology and other branches. The chemical study of various natural substances is called bioorganic chemistry. The subject that studies the biological functions of various inorganic substances is called bioinorganic chemistry or inorganic biochemistry. Since the 1960s, the integration of biochemistry and other disciplines has produced some marginal disciplines, such as biochemical pharmacology, paleontology and chemical ecology. Or according to different application fields, it can be divided into medical biochemistry, agricultural biochemistry, industrial biochemistry, nutritional biochemistry and so on.
