Vitamins: Definition, Examples, Types, Sources and Uses

Definition: The organic compounds which are required by our bodies to prevent specific diseases but cannot be produced by our bodies are called vitamins.

These compounds must be present in our diet in addition to proteins, fats, carbohydrates and minerals.

Examples, vitamin A, vitamin B Complex, vitamin C, vitaminD

Types of vitamins

There are two types of vitamins.

Fat soluble vitamins

Water insoluble vitamins

Fat soluble vitamins

A vitamin that is soluble in fats is called fat soluble vitamin. For example, vitamins A, D,E and K.

Taking excessive amount of fat soluble vitamins can be harmful. For example, excessive amount of vitamin A can cause irritability, dryness of skin and pressure inside the head. Similarly, Taking excessive amount of vitamins D can cause pain in bones, hard deposits in joints and kidneys. And weight loss.

Water insoluble vitamins

A vitamin that dissolve in water is called water soluble vitamin. For example, vitamin B (complex) and C.

Our bodies have a limited capacity to store these vitamins. If it is taken in excess, these are readily excreted from the body. However, if water soluble vitamins are not toxic even if taken in excess.

Sources, uses and diseases due to their deficiency

Sources

Milk, butter 🧈, fish oil 🐟, 🛢, eggs 🥚, fresh green vegetables

Chemistry

T he Federal Board of Intermediate & Secondary Education (FBISE) is an autonomous body that conducts the examinations in the institutions affiliated with it in Pakistan as well as abroad. Punjab government has ten boards of Intermediate & Secondary Education including Bahawalpur Board, D.G. Khan Board, Faisalabad Board, Gujranwala Board, Lahore Board, Multan Board, Rawalpindi Board and Sargodha Board and each board conducts exams independently. Federal Board generally follows the international norms and standards. Federal Board paper pattern is quite tricky and similar to O-Level and A Level formats. These questions need conceptual approach to be solved. Punjab board’s Paper pattern is comparatively easy up to some extent. We are currently focusing on the subject of Chemistry for all classes affiliated with Federal Board ( IX , X , XI , XII ) and Punjab Board ( XI XII ). We intend to extend it to all subjects in future. After reading All Student Notes, studen

Basic Definitions| Matter, Substance, Element, Compound. Mixture, Homogeneous mixture and Heterogeneous mixture Examples (for Grade - 9 students)

Basic Definitions| Matter, Substance, Element, Compound. Mixture, Homogeneous mixture and Heterogeneous mixture Examples (for Grade - 9 students) Question: Define following terms: Matter Substance Element Compound Mixture Homogeneous mixture Heterogeneous mixture Answer Matter: Matter can be anything that occupies space (volume) and has mass. Example, book, table, walls, chairs, plants, animal, etc. Substance: Substance is a matter that has a particular set of characteristics that differ from the characteristics of another kind of matter. For example, oxygen, water, carbon monoxide, carbon dioxide, urea, glucose, common salt etc are different substances. Element: A substance that cannot be converted to other simpler substances is known as an element. or A substance which has all atoms of same atomic number is called element. For example substances like oxygen, hydrogen, iron, copper, aluminum etc. are elements. Compound: A compound is a pure substance that co

Experimental Techniques in Chemistry

Analytical Chemistry: The branch of chemistry that deals with the quantitative and qualitative analysis of substances is called Analytical Chemistry. Question 2.1: What is difference between quantitative and quantitative analysis? What are various steps involved in quantitative analysis? Answer: Qualitative analysis: The analysis in which elements are identified is called qualitative analysis. Quantitative analysis: The analysis in the form of which relative amounts of elements are determined is called quantitative analysis. There are four main steps involved in quantitative analysis. 1. Obtaining a sample for analysis 2. Separation of desired constituent 3. Measurement and calculations of results 4. Drawing conclusions from analysis Question 2.2: Define filtration. How do we select the filter media? Answer: The process of separating solids or suspended particles from liquids by using a filter medium is called filtration. Question 2.3: Describe filt

Alkyl halides

The compounds in which one hydrogen atom of alkane is replaced by a halogen atom is called alkyl halide. Alternatively, The halogen derivatives of alkanes with general formula R-X are Halide called alkyl halide. For example CH4 ( Alkane ) CH3-X ( Alkyl halide ) X = F, Cl, Br and I Table Of Contents Types Mono, di, tri or poly haloalkane depending upon the number of halogen atom. For example C lassification of Alkyl Halides Alkyl halides can be classified as primary, secondary and Tertiary alkyl halides. 1. Primary Alkyl Halides The alkyl halides in which a halogen atom is bonded with primary carbon is called primary alkyl halide. Primary carbon is the carbon that is attached one or no carbon atom. The Secondary Alkyl Halides The alkyl halides in which a halogen atom is bonded with secondary carbon are called secondary alkyl halide. Secondary carbon is the carbon that is attached with two carbon atoms. For example

Shielding Effect (Grade 9 Students) and its trend in Periodic Table.

Question: What is shielding effect? Give its trends in the periodic table. Answer . Shielding Effect The decrease in force of attraction between nucleus and valence electrons due to presence of inner shell electrons is called shielding effect. It is also known as screening effect. It increases with increase in inner shell electrons. For example, Mg has greater shielding effect than Be. This is because Mg has eight more inner-shell electrons than Be. Trend in Periodic Table In period As we move from left to right in a period, shielding effect remains constant. Reason is that the number of inner shell electrons remains constant along the period. In group As we move from top to bottom in a group, shielding effect increases. This is due to fact that the number of inner shell increases and hence, inner shell electrons also increase. For example, Na has greater shielding effect than Li because of eight more inner shell electrons than Li. Example 3.5 Identi

Class 9 Electrochemistry MCQs and Answers with explanation

1. In which of the following changes, the nitrogen atom is reduced? a) N 2 to NO b) N 2 to NO 2 c) N 2 to NH 3 d) N 2 to HNO 3 ... Answer is b) Explanation: Oxidation number of an elemnet in free state is zero. So Oxidation No. of N 2 = 0 Calculate oxidation No. of nitrogen in each compound. Option a) Let, oxidation No. of N in NO is X. Sum of oxidation numbers of all atoms present in a neutral compound is zero. Oxidation No. of N + (Oxidation No. of O ) = 0 X-2 = 0 X = +2 X = +2 Oxidation No. of N in NO 2 is +2 Option b) Let, oxidation state of N in NO 2 is X. Sum of oxidation numbers of all atoms present in a neutral compound is zero. Oxidation No. of N + 2(Oxidation No. of O ) = 0 X + 2(-2) = 0 X -4 = 0 X = +4 Oxidation No. of N in NO 2 is +4 Option c) Let, oxidation state of N in NH 3 is X. Sum of oxidation numbers of all atoms present in a neutral compound is zero. Oxidation No. of N + 3(Oxidation No. of H )
