What is peptide linkage?
Show Hint
Solution and Explanation
A peptide linkage is a covalent bond that joins two amino acids through the carboxyl group (\(-COOH\)) of one amino acid and the amino group (\(-NH_2\)) of another, forming a \(-CONH-\) bond. This reaction results in the elimination of water (\(H_2O\)) and is known as a peptide bond. \[ \text{Amino acid 1} - \text{COOH} + \text{Amino acid 2} - \text{NH}_2 \rightarrow \text{Peptide bond} + H_2O \]
Top Questions on Proteins
- The $\alpha$-amino acids are the building blocks of proteins. All $\alpha$-amino acids exist as zwitter ions due to which they show amphoteric behaviour. All amino acids are joined through peptide bonds. Proteins are broadly classified as globular proteins and fibrous proteins. Globular proteins are water soluble, whereas fibrous proteins are not. The complete structure of protein is discussed at four different levels i.e. primary, secondary, tertiary and quaternary structures. Protein loses its biological activity in denatured form.

- A battery of emf \( E \) and internal resistance \( r \) is connected to a rheostat. When a current of 2A is drawn from the battery, the potential difference across the rheostat is 5V. The potential difference becomes 4V when a current of 4A is drawn from the battery. Calculate the value of \( E \) and \( r \).
