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. \[ \text{Amino acid 1} - \text{COOH} + \text{Amino acid 2} - \text{NH}_2 \rightarrow \text{Peptide bond} + H_2O \]
What is the difference between native protein and denatured protein?
If vector \( \mathbf{a} = 3 \hat{i} + 2 \hat{j} - \hat{k} \) \text{ and } \( \mathbf{b} = \hat{i} - \hat{j} + \hat{k} \), then which of the following is correct?
