Biochemistry is a nomenclature of biochemistry

Categories: Education Science.

Problem description: What is biochemistry? It would be useful to give some examples of the definition and the aspects involved in its study.

Analysis: 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.

Career Prospects Most biology graduates (biochemiker) work in universities and research institutes. In addition, it is possible to work in the manufacturing industry, especially in the food industry, beverage production, pharmaceutical manufacturing, detergent manufacturing and fertilizer and plant protection material manufacturing.

Majors in a comprehensive university.

Standard length of study: 9 to 10 semesters. In some cases, 8 semesters, 6 semesters of study, passing the examination can be awarded a bachelor's degree (bachelor's).

Foundation Studies: Lectures and internships in organic chemistry, inorganic chemistry, analytical chemistry, physical chemistry, botany, zoology, physics and anatomy, and physiology. At the end of the basic studies in chemistry and biology, a mid-term exam (diplom-vorpruefung) is required.

Graduation degrees: Diplompruefung, Bachelor's, Master's.

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

It is mainly used to study the structure and function of various components in cells, 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.

The term biochemistry appeared around the end of the 19th and early 20th centuries, but its origins can be traced much further back to its early history, and its early history is part of the early history of physiology and chemistry. For example, in the 80s of the 18th century, a-l.

Lavoisier proved that respiration is oxidation like combustion, and almost at the same time scientists discovered that photosynthesis is essentially the inverse process of plant respiration.

Translation refers to the information of the nucleic acid base chain, and the corresponding polypeptide chain is synthesized according to the way that three bases determine one amino acid under the action of peptide synthase.

Biochemistry refers to the sub-discipline of chemistry that uses chemical methods and theories to study life. Its mission is to understand the chemical composition and structure of organisms and the various chemical changes in life processes. From the early study of the overall composition of organisms, to the precise analysis of various tissue and cell components.

Important biological macromolecules (such as proteins, nucleic acids, etc.) are being analyzed using spectroscopic analysis, isotope labeling, X-ray diffraction, electron microscopy, and other physical and chemical techniques to illustrate the diverse functions of these biomacromolecules and their specific structural relationships.

English: biochemistry

Translation is the second step in the process of protein biosynthesis (part of gene expression, which also includes transcription), and translation is the process of decoding the "order of bases" (nucleotide sequences) in a mature messenger RNA molecule (generated by DNA through transcription) according to the central law of the genetic code, and generating the corresponding specific amino acid sequence.

However, many transcription-generated RNAs, such as transport RNAs (tRNAs), ribosomal RNAs (RNAs), and micronuclear RNAs (snRNAs), are not translated into amino acid sequences.

Extended information: Raw materials for translation: mRNA, tRNA, 20 amino acids, energy, enzymes, ribosomes. The process of translation can be roughly divided into three stages: initiation, extension, and termination.

Translation takes place mainly in ribosomes within the cytoplasm, where amino acid molecules are catalyzed by aminoacyl-tRNA synthetase to specific transport RNAs and are carried to ribosomes. The resulting polypeptide chains (i.e., amino acid chains) need to be properly folded to form proteins, and many proteins also require post-translational modifications in the endoplasmic reticulum after translation is completed to be truly biologically active.

Biochemistry is the study of chemical reactions and interactions that occur in living organisms; Biochemistry is a compulsory discipline that uses chemical methods and theories to study living matter.

Since biochemistry is an interdisciplinary discipline, both biochemistry students under chemistry and biology students can apply for this major, but applicants for biochemistry under biology must have research experience in chemistry. There are also some related disciplines under engineering that can also apply for this major, such as biological or chemical engineering, but it must be related to the research of this major.

Development of biochemistry:The biochemistry major is developed on this basis, which mainly cultivates compound application talents with solid basic knowledge of chemistry and biology and a wide range of knowledge in the interdisciplinary fields of chemical biology, proficient in chemistry and related biology experimental skills, strong sense of innovation, high comprehensive quality, and can be engaged in teaching, scientific research, technology development and management in chemical biology, chemistry, life, medicine, materials, chemical engineering, environmental protection and other related fields.

Biochemical explanations.

Applying the theories and methods of chemistry to the study of biology is a marginal science.

Word Decomposition Explanation of Biology Living objects have the ability to grow, develop, and reproduce, and can exchange substances with the surrounding environment through metabolism. Animals, plants, and microorganisms are all living creatures Forest creatures only a few goshawks hovering in the sky, and they can't see the creatures next to them.;; Meng Jiangnu explains in detail.

It generally refers to the interpretation of all chemistry in nature, and the detailed explanation of the discipline that studies the composition, structure and properties of matter and its transformation. The science that studies the composition, structure, properties, resistance, and laws of change of matter is a basic discipline in the natural sciencesRefers to celluloid .

For example, this comb is chemical.

1. Nucleosome: A structural unit used to package chromatin, which is composed of DNA strands wound around a histone nucleus.

2. DNA denaturation (DNADENATURATION) Under the action of physical and chemical factors, the two complementary strands of the DNA double helix are loosened and become single strands, which leads to changes in the physicochemical properties and biological properties of DNA, which is called DNA denaturation.

3. DNA renaturation: the process by which denatured DNA can re-associate two separate strands into a double helix structure under appropriate conditions.

4. Melting temperature (TM): the temperature corresponding to the midpoint value of the increase in ultraviolet absorption in DNA thermal denaturation. Or the pyrolysis chain temperature.

5. Hyperchromic effect: when DNA is denatured, the absorption of ultraviolet light at 260nm increases.

6.Hypochromic effect: A phenomenon in which ultraviolet absorption decreases with the refolding of nucleic acids.

7.Endonuclease (exonuclease): an enzyme in ribonucleases and deoxyribonucleases that hydrolyze phosphodiester bonds within nucleic acid molecules.

8.Exonuclease: An enzyme that hydrolyzes nucleotides one by one from one end of the nucleic acid strand.
