Important Topics for Xam Idea Class 12 Chemistry Chapter 16 – Chemistry in Everyday Life

Chemistry encompasses all the areas of human life, and the principles of chemistry have been used for the benefit of mankind. Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life includes all the concepts of this chapter. They give you complete knowledge of the topics and subtopics. The main points given in this chapter are as follows –

  • Drugs and Their Classification

This part of the chapter tells you that drugs are the low molecular weight molecules chemical agents which affects human metabolism and cure the targeted ailments when taken in prescribed doses. These medicines are used to cure different ailments. Chemotherapy is the use of chemicals for therapeutic effect, and all the drugs are nothing else but chemicals.

This part of the chapter tells you that drugs can be classified on the basis of following

  1. Pharmacological effects where drugs are classified according to the use,
  2. Drug action that is the mechanism followed by drug inside the body to produce the effect,
  3. The chemical structure where drugs of the same class would have a basic chemical core common in all
  4. Molecular targets depending on the structure of the receptors.

Our Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life covers all the information in a comprehensive manner.

  • Drug Target Interaction

This part of the chapter tells you that drugs work by interacting with the target to impart their action. Drugs act upon target biological macromolecules such as proteins, lipids, carbohydrates and nucleic acids. Enzymes responsible for biocatalysis are proteins in nature, receptors responsible for the communication system in the body are proteins.

In this part of the chapter, drug-target interaction is explained using examples of enzymes and receptors. Drugs are designed to interact with some specific targets so that they do not affect other targets, this minimizes the side effects and specifies the drug action. Our Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life provides accurate and concise answers to all the questions related to this topic.

  • Therapeutic Actions of Different Classes of Drugs

Different classes of drugs act through a different mechanism of action and based on that they are classified. This portion of the chapter teaches you regarding the main classes of drugs according to their therapeutic action.

You come to know here, that the drugs which compete with histamine molecule released by our body in response to foreign invasion, stopping its effect in the body, are known as antihistamines. Terfenadine is an example of an antihistamine drug. Antacids are the class of compounds which counter the hyperproduction of acids in the stomach. An example is a cimetidine.

Tranquillizers are neurologically active molecules intercepting the message transfer mechanism from nerve to receptor, chlordiazepoxide is a tranquillizer. Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life help you memorize the name of drugs and their mechanism of action correctly.

Further, you learn here that analgesics are used to reduce pain without causing any neurological effect. The painkillers may be of two types – non-narcotic and narcotic. Antimicrobial medicines are those drugs which destroy or prevent development/growth of pathogens such as bacteria, viruses, fungi, other pathogens. Antibiotics are used for either checking the growth (bacteriostatic) or killing (bactericidal) the bacteria.

Here you will also learn that antiseptics and disinfectants are class of compounds which are used to kill or check the growth of microorganisms when applied on affected animate surfaces or inanimate surfaces. A substance can act both as disinfectant and antiseptic depending upon its concentrations. Antifertility drugs are the compounds which are used to control population growth. An example is norethindrone. Our Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life help you in preparing all these topics and getting good marks in board exams.

  • Chemicals in Food

Here you will learn that there are several chemicals which are added to food in order to enhance their flavour and colour and make them more palatable. This part of the chapter tells you that

food additives are added to food in order to preserve them, enhance their appeal, increasing their nutritive value, stabilizing them.

This part of the chapter tells you that, use of artificial sweetening agents has become very common, which are added to make food sweet as an alternative to natural sweeteners which increase calorie intake in the body. Food preservatives are widely used to prevent spoilage of food while manipulating various mechanisms of actions. Our Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life is written in a methodical and descriptive manner, helping you to learn and revise effectively.

  • Cleansing Agents

Here you learn that soaps are used from time immemorial to remove dirt stuck on cloth and skin. This part of the chapter tells you that detergents are the chemical compounds used for cleaning purposes. Soaps and synthetic detergents are two types of detergents. Soaps are sodium or potassium salts of long-chain fatty acids.

This part of the chapter tells you that the soaps are prepared through the process of saponification of long-chain fatty acids. There are many varieties of soaps manufactured these days. Those are toilet soaps, soaps that float on water, transparent soaps, medicated soaps, shaving soaps, scouring soaps etc. which are used according to the requirement. These are prepared by adding some additives with different properties. Our Xam Idea Class 12 Chemistry Solutions Chapter 16 – Chemistry in Everyday Life are the best study material available to learn these topics.

Here you will learn that synthetic detergents do not contain soap but show all the properties of soap. This part further tells you that synthetic detergents are classified into three main categories, namely, anionic, cationic and non-ionic, with each category having its specific uses. Here you will also learn that detergents can have a straight-chain or branched-chain fatty acid part. This section also tells you that the detergents with the straight-chain hydrocarbons are preferred over the branched-chain ones because the latter ones are non-biodegradable, causing environmental pollution.
