Riboflavin- Vitamin B2

Brief Summary

This video provides an overview of riboflavin (Vitamin B2), including its alternative names, properties, chemical structure, and derivatives. It highlights its role as a coloring agent, its stability to heat but sensitivity to light, and its chemical composition involving a dimethyl isoaloxazine ring connected to ribetol.

  • Riboflavin, also known as Vitamin B2, is also called Warburg yellow enzyme.
  • It functions as a coloring agent, providing yellow to orange color in foods.
  • Chemically, it consists of a dimethyl isoaloxazine ring connected to ribetol.

Introduction to Riboflavin (Vitamin B2)

The video introduces riboflavin, also known as Vitamin B2, and suggests remembering it as "B2R." It is also referred to as Warburg yellow enzyme and functions as a food coloring agent, imparting a yellow to orange color. The presenter suggests using riboflavin in Diwali sweets for its coloring properties. Riboflavin is noted to be heat stable but light sensitive.

Chemical Structure of Riboflavin

The discussion shifts to the chemistry of riboflavin, explaining that it contains a dimethyl isoaloxazine ring. This ring is connected to ribetol via a nitrogen atom. Ribetol is described as a derivative of ribose, where the aldehyde group is replaced by alcohol. The combination of dimethyl isoaloxazine and ribetol forms the structure of riboflavin.

Riboflavin Derivatives

The video explains that when riboflavin is connected to a phosphate group, it forms riboflavin phosphate, also known as flavin mononucleotide (FMN).

You can remember it as a B2R, R represents riboflavin, it is also known as warbur yellow enzyme of cellular respiration, it is also a colouring agent, food colouring agent, it gives yellow to orange colour to the food and you can use this vitamin, this Diwali for the preparation of various foods which are yellow to orange in colour, okay. So use riboflavin, this

0:52 Diwali for the preparation of various sweets, then it is heat stable and light sensitive, now coming to the chemistry part of riboflavin, this riboflavin contains, then coming to the chemistry, it contains dimethyl isoaloxazine ring, this is the nitrogen of this dimethyl isoaloxazine ring and to this nitrogen there is ribetol, this

1:42 ribetol attached to the nitrogen, this ribetol is a derivative of ribose in which aldehyde group is replaced by alcohol, so this structure that is dimethyl isoaloxazine connected to the ribetol, this is known as riboflavin.
