What is chemistry? Get to know her beautifully

 What is chemistry

Chemistry is the science that studies matter and its properties, how and why substances combine or separate to form another substance and how it interacts with energy.Many people think that chemists wear a white coat and they test and mix strange liquids in the laboratory, but in fact we are all chemists. Understanding basic chemistry concepts is part Important for nearly every profession.


Everything in existence is made up of matter, even our bodies.Chemistry is present in everything we do, like farming, cooking food, cleaning our homes and our bodies, and even launching a space rocket. Chemistry is one of the physical sciences that helps us describe and explain our world.



 

Departments of Chemistry

Chemistry is divided into 5 major departments, each of which has several fields of study.


Analytical chemistry: Qualitative and quantitative observation is used to define and quantify the physical and chemical properties of substances.


Physical chemistry: This section combines chemistry and physics. Both thermodynamics and quantum mechanics are two important branches of physical chemistry.


Organic chemistry: This section is concerned with the study of compounds that contain the element carbon, as carbon has many unique properties that allow it to form complex chemical bonds and very large molecules. Organic chemistry is known as (the chemistry of life) because all the molecules that make up living tissues have carbon as part From its composition.


Inorganic chemistry: It studies materials that are not part of carbon, such as minerals and gases.


Biochemistry: It is the study of the chemical processes that occur within living organisms.



 

fields of study

There are many and varied fields of study within these departments, many of which have a direct impact on our daily life. Chemists strive to improve many things, such as the food we eat, the clothes we wear, and the materials used to build our homes. Chemistry helps protect our environment and search for new sources of energy.


Food Chemistry: Food science deals with the basic components of food, which are carbohydrates, fats and proteins.


Carbohydrates are sugars and starches, and they are the chemical fuel for cells to function efficiently.


Fats, along with oils, are key parts in making cell membranes lubricate the systems inside our bodies.


Proteins are complex molecules composed of 100 to 500 or more amino acids that are linked in chains together and folded into a three-dimensional form that is appropriate for the structure and function of each cell.


Environmental Chemistry: Chemists study how chemicals interact with the natural environment.


Chemists in this field try to understand the chemicals and chemical reactions involved in natural processes in water, air, and soil.


Agricultural chemistry: Agricultural chemistry is related to substances and chemical reactions associated with the production, protection and use of crops and livestock.


It is a multidisciplinary field that overlaps with many other sciences.


Chemists in this field are developing the fertilizers, pesticides and herbicides needed to produce more efficient crops.


Chemical Engineering: Chemical engineers research and develop new materials or processes that involve chemical reactions.


Chemical engineering combines the concepts of chemistry, engineering, and economics to solve technological problems.


The job of a chemical engineer is based on industrial applications and developing a new product.


Geochemistry: Geochemistry combines chemistry and earth sciences (geology) to study the formation and interactions between materials found on the earth.


Often, chemists in this field spend more time doing field studies than other chemical sciences.


Chemists may work in the oil and gas industry to help find new sources of energy reserves.


They may also work on pipelines and oil platforms to prevent chemical reactions that could cause explosions or spills.



 

Forensic chemistry: Chemists in this field capture and analyze physical evidence left over at crime scenes to help identify the identities of the people involved and also to answer other vital questions regarding how the crime occurred.


Forensic chemists use a wide variety of methods of analysis, such as chromatography and spectroscopy.

Is telepathy become a reality?

 For the first time, researchers have connected electronically the brains of pairs of mice to enable them to communicate directly to solve simple behavioral puzzles. Another test of this idea succeeded in connecting the brains of two animals thousands of miles apart - one in Durham, North Carolina, and the other in Natal, Brazil.   Miguel Nicolelis, M.D. and Philosophy, lead author of the publication and professor of neurobiology at Duke University, School of Medicine, said: “Our previous studies with mediation between the brain and the machine have convinced us that the mouse brain is more plastic than we previously thought. In those experiments, the mouse brain was able to easily adapt to receive information from devices outside the body as well as learn how to process the invisible infrared rays generated by an artificial sensor. So the question we asked was, 'If the brain is able to absorb signals from artificial sensors, can it absorb the information input from sensors fr...

What are the benefits of chewing food slowly?

 Food and eating is usually believed by many to be those processes and reactions that take place in the stomach and intestines, while the digestive process begins mainly in the mouth, with chewing. Chewing food makes it easier to digest by breaking it into smaller pieces, and it gives more time for food to mix with saliva, which increases the body's ability to extract all the possible nutrients in the food. The number of times needed to chew food varies depending on what the food is itself. Each food takes a certain number of times to break down and lose its hardness and structure, so that it is easier to digest. The average number of chewing times is approximately 32 times per bite, and the number of times decreases with eating soft and full of water, and foods that need more force to chew, such as steaks and nuts, may require chewing up to 40 times, and other foods such as watermelon need a number of times Much less, up to 10 or 15 times. Chewing food is the first step in the dig...

How do our cells build protein?

 Proteins are among the most versatile macromolecules in living systems, as they perform biological functions on a large scale, and this is reflected in their structural diversity. Proteins consist mainly of (carbon, hydrogen, nitrogen, oxygen, and sulfur), in addition to some other elements that are found in specific specialized proteins, such as iron in hemoglobin protein and phosphorous in casein protein. All proteins consist of building blocks known as amino acids, which are linked together by bonds called peptide bonds. It is worth noting that there are 22 different amino acids in the proteins of living organisms. The process of building protein depends on ribosomes along with nucleic acids, which include two types: First: DNA And the second: all types of RNA (messenger RNA, tRNA, and rRNA, which is the functional unit of the ribosome). The process of building proteins in a cell consists of two main steps: 1- The transcription process 2- The translation process Transcription p...
