Introduction to Biological Terminology in English

Biological studies encompass a wide range of disciplines, each with its own unique set of terminology. Understanding and being able to communicate these terms in English is crucial for students and professionals in the field of biology. In this article, we will explore some essential biological terms and their English translations.

1. Cell - A fundamental unit of life, consisting of a membrane-bound structure that carries out various functions.

2. DNA - Deoxyribonucleic acid, a molecule that contains the genetic instructions for the development and functioning of all living organisms.

3. Protein - Large molecules composed of amino acids that play essential roles in various biological processes, such as enzymes, structural components, and signaling molecules.

4. Gene - A segment of DNA that contains the instructions for producing a specific protein or RNA molecule.

5. Evolution - The process of gradual change in species over time, driven by natural selection and genetic variation.

6. Photosynthesis - The process by which plants and some microorganisms convert sunlight, carbon dioxide, and water into glucose and oxygen.

7. Respiration - The process of breaking down glucose to produce energy, typically in the presence of oxygen (aerobic respiration) or without oxygen (anaerobic respiration).

8. Mitosis - Cell division resulting in two identical daughter cells with the same number of chromosomes as the parent cell.

9. Meiosis - Cell division that produces gametes (sperm and eggs) with half the number of chromosomes as the parent cell.

10. Enzyme - A protein that catalyzes biochemical reactions by lowering the activation energy required for the reaction to occur.

11. Ecology - The study of the interactions between organisms and their environment.

12. Biodiversity - The variety of living organisms in a particular area, including genetic, species, and ecosystem diversity.

13. Microorganism - A microscopic organism, such as bacteria, viruses, or fungi.

14. Adaptation - A characteristic or behavior that enhances an organism's survival and reproduction in its environment.

15. Homeostasis - The ability of an organism to maintain internal stability and balance despite external changes.

These are just a few examples of the many biological terms used in English. Building a strong foundation in biological terminology is essential for effective communication and understanding within the field of biology.

Advanced Biological Terminology in English

In the previous article, we explored some essential biological terms in English. In this article, we will dive deeper into advanced biological terminology that is commonly used in specialized fields within biology.

1. Genomics - The study of an organism's entire genome, including the arrangement and function of genes.

2. Proteomics - The study of the structure, function, and interactions of proteins within an organism.

3. Bioinformatics - The application of computer science and statistical analysis to biological data, such as DNA sequences, protein structures, and gene expression profiles.

4. Epigenetics - The study of heritable changes in gene expression without alterations to the underlying DNA sequence.

5. Metabolism - The set of chemical reactions that occur within an organism to convert food into energy and other essential molecules.

6. Phylogenetics - The study of the evolutionary relationships among different species, based on similarities and differences in their genetic sequences.

7. Immunology - The study of the immune system and its response to pathogens, allergens, and other foreign substances.

8. Neurobiology - The study of the structure and function of the nervous system, including the brain, spinal cord, and peripheral nerves.

9. Endocrinology - The study of the endocrine system and the hormones it produces, which regulate various bodily functions.

10. Biotechnology - The use of living organisms or their products to create or modify products, processes, or organisms for specific applications.

11. Pharmacology - The study of how drugs interact with biological systems, including their absorption, distribution, metabolism, and excretion.

12. Developmental Biology - The study of the processes by which organisms grow and develop from a single cell to a complex organism.

13. Molecular Biology - The study of biological molecules, such as DNA, RNA, and proteins, and their interactions within cells.

14. Ecological Succession - The gradual change in species composition and community structure over time in a particular ecosystem.

15. Genetically Modified Organism (GMO) - An organism whose genetic material has been altered using genetic engineering techniques.

These advanced biological terms provide a glimpse into the diverse fields and sub-disciplines within biology. Mastering these terms is crucial for professionals and researchers in specialized areas of biological study.

  3.寡糖(oligosaccharide):又称低聚糖,是由2~20个单糖通过糖苷键连接而成的糖类物质。可分为二糖、三糖、四糖、五糖等。

  4.二糖(disaccharide):又称双糖,是最简单的寡糖,由2个分子单糖缩合而成。常见的二糖有蔗糖(sucrose)、乳糖(lactose)、麦芽糖(maltose)。

  5.多糖(polysaccharide):由多分子单糖或单糖的衍生物聚合而成。

  6.同多糖(homopolysaccharide)由同一种单糖聚合而成,如淀粉(starch)、糖原(glycogen)、纤维素(cellulose)。

  7.杂多糖(heteropolysaccharide)有不同种单糖或单糖衍生物聚合而成,如透明质酸(hyaluronicacid,HA)、肝素(heparin,Hp)等。

  8.糖胺聚糖(glycosaminoglycan,GAG)又称粘多糖,氨基多糖和酸性多糖。是动植物特别是高等动物的结缔组织中的一类结构多糖。例如透明质酸.硫酸软骨素.硫酸角质素等。

  9.蛋白聚糖(proteoglycan):由一条或多条糖胺聚糖和一个核心蛋白共价连接而成,糖含量可超过95%。主要存在于软骨、腱等结缔组织,

  构成细胞间质。由于糖胺聚糖有密集的负电荷,在组织中可吸收大量的水而赋予粘性和弹性,具有稳定、支持和保护细胞的作用。

  10.糖蛋白(glycoprotein):短链寡糖与蛋白质以共价键连接而形成的复合物,其总体性质更接近蛋白质。糖蛋白的寡糖链参与分子识别和细胞识别。

  11.糖脂(glycolipid)

  12.脂多糖(lipopolysaccharide)

  第二部分脂质

  1.脂质:lipid是一类低溶于水而高溶于非极性溶剂的生物有机分子。

  2.储存脂质(storagelipid)、结构脂质(structurelipid)、活性脂质(activelipid)

  3.单纯脂质(simplelipid)、复合脂质(compoundlipid)、衍生脂质(derivedlipid)

  4.脂肪(真脂(fat)、脂肪酸(fattyacid,FA)

  5.必需脂酸(essentialFA)亚油酸、亚麻酸、花生四烯酸等多不饱和脂酸是人体不可缺乏的营养素,不能自身合成,需从食物获取。

  6.磷脂酰胆碱(phosphatidylCholine,PC)也称卵磷脂(lecithin)可降低胆固醇,增加高密度脂蛋白的作用,防止降低动脉硬化。

  7.胆碱(Choline)、胆固醇(cholesterol)

  8.脂蛋白(lipoprotein)脂质与蛋白质以非共价键结合而成的复合物a.乳糜微粒(chylomicron)主要功能是从小肠转运三酰甘油、胆固醇以及其他脂质到血浆和其他组织。

  c.中间密度脂蛋白(intermediatedensitylipoprotein,IDL)一部分被肝脏直接吸收,一部分转化为LDL。

  d.低密度脂蛋白(lowdensitylipoprotein,LDL)把胆固醇从肝脏运送到全身组织,过量时则其携带的胆固醇便积存在动脉上引起动脉硬化。e.高密度脂蛋白(highdensitylipoprotein,HDL)会将胆固醇从周边组织输送到肝脏代谢

  第三部分:氨基酸以及蛋白质共价结构

  1.单纯蛋白质(simpleproein):许多蛋白质仅有氨基酸组成,不含其它化学成分。

  2.缀合蛋白质(conjugatedprotein):许多其它蛋白质含有除氨基酸外的各种化学成分作为其结构的一部分。

  3.辅基(prostheticgroup)配体(ligand):许多其它蛋白质含有除氨基酸外的各种化学成分作为其结构的一部分,这些非蛋白质部分,称为辅基。

  10.氨基酸残基(aminoacidresidue):肽链中的氨基酸因为参加肽键的形成已经不是原来完整的分子,故称为氨基酸残基。

  11.蛋白质(protein)、肽(或肽链()peptidechain)、肽基肽单位(petpidegroup)

  12.蛋白质的一级结构(primarystructure):多肽链中氨基酸的排列顺序,包括二硫键的位置称为蛋白质的一级结构。
