Answer the question on the basis of the passage given below:

Proteins are the polymers of about twenty different \(\alpha \)-amino acids which are linked by peptide bonds. Proteins perform various structural and dynamic functions in the organisms. Proteins which contains only \(\alpha \)- amino acids are called simple proteins. The secondary or tertiary structures of proteins gets disturbed on change of pH or temperature and they are not able to perform their functions. This is called denaturation of proteins. Enzymes are biocatalysts which speed up the reactions in bio systems. Vitamins are accessory food factors required in the diet. They are classified as fat soluble (A, D, E and K) and water soluble (B and C). Deficiency of vitamins leads to many diseases. Nucleic acids are the polymers of nucleotides which in turn consists of a base, a pentose sugar and phosphate moiety. Nucleic acids are responsible for the transfer of characters from parents to offspring’s. There are two types of nucleic acids: DNA and RNA. DNA contains a five carbon sugar molecule called 2-deoxyribose whereas RNA contains ribose.

Which of the following vitamin cannot be stored in our body?

Vitamin \(B_2\)

The correct answer is option 4. Vitamin \(B_2\).

Vitamin \(B_2\), also known as riboflavin, is a water-soluble vitamin. This means it dissolves in water and is not stored in the body to any significant extent. When you consume foods containing riboflavin, your body absorbs what it needs, and any excess is excreted through urine. Unlike fat-soluble vitamins, which can be stored in the body's fatty tissues and liver, water-soluble vitamins like riboflavin do not accumulate in the body over time.

Since Vitamin \(B_2\) is not stored in the body, it needs to be consumed regularly through diet to maintain adequate levels. This makes it important to include riboflavin-rich foods in your daily meals or consider supplementation if your diet lacks sufficient amounts of this vitamin. Common dietary sources of riboflavin include dairy products, lean meats, eggs, nuts, green leafy vegetables, and fortified cereals.
