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.

- Chandan, Deepak and Elvish were partners in a firm sharing profits and losses in the ratio of 1 : 2 : 2. Their Balance Sheet as at 31st March, 2024 stood as follows:
Balance Sheet of Chandan, Deepak and Elvish as at 31st March, 2024
Chandan retired from the firm on 1st April, 2024 on the following terms:Liabilities Amount (₹) Assets Amount (₹) Capitals: Fixed Assets 27,00,000 Chandan 7,00,000 Stock 3,00,000 Deepak 5,00,000 Debtors 2,00,000 Elvish 3,00,000 Cash 1,00,000 General Reserve 4,50,000 Creditors 13,50,000 Total 33,00,000 Total 33,00,000
[(i)] Fixed assets were to be depreciated by 10%.
[(ii)] Debtors of ₹ 30,000 were to be written off as bad debts.
[(iii)] Goodwill of the firm was valued at ₹ 6,00,000 and the retiring partner’s share is adjusted through the capital accounts of the remaining partners.
[(iv)] Chandan was paid through cash brought in by Deepak and Elvish in such a way so as to make their capitals proportionate to their new profit sharing ratio. Prepare Revaluation Account and Partners’ Capital Accounts. A coil of 60 turns and area \( 1.5 \times 10^{-3} \, \text{m}^2 \) carrying a current of 2 A lies in a vertical plane. It experiences a torque of 0.12 Nm when placed in a uniform horizontal magnetic field. The torque acting on the coil changes to 0.05 Nm after the coil is rotated about its diameter by 90°. Find the magnitude of the magnetic field.
