Vitamins: A Quick Revision

Questions related to Vitamins is most common for all kinds of competitive exams and we expect them in the examination. here we have designed vitamins in simple way go through and brush up your knowledge.

Vitamins are a group of substances that are essential for normal cell function, growth, and development. A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts. An organic chemical compound (or related set of compounds) is called a vitamin, when the organism cannot synthesize the compound in sufficient quantities, and must be obtained through the diet or supplements like these immune booster vitamin products; thus, the term “vitamin” is conditional upon the circumstances and the particular organism. Vitamins are classified by their biological and chemical activity, not their structure.Thus, each “vitamin” refers to a number of vitamer compounds that all show the biological activity associated with a particular vitamin.


  • Vitamins have diverse biochemical functions. Some, such as vitamin C, have immunity-boosting elements, and the benefits of liposomal vitamin c comprise detox support, collagen production, among others.
  • The largest number of vitamins, the B complex vitamins, function as precursors for enzyme cofactors, that help enzymes in their work as catalysts in metabolism. In this role, vitamins may be tightly bound to enzymes as part of prosthetic groups: For example, biotin is part of enzymes involved in making fatty acids.
  • Although these roles in assisting enzyme-substrate reactions are vitamins’ best-known function, the other vitamin functions are equally important.
  • Vitamins have been produced as commodity chemicals and made widely available as inexpensive semisynthetic and synthetic-source multivitamin dietary and food supplements and additives, since the middle of the 20th century.

Types and Examples of Foods
