Enlist the points of difference between fibrous and globular proteins.

(N/A) The differences between fibrous and globular proteins are as follows:
| No. | Fibrous Proteins | Globular Proteins |
| :--- | :--- | :--- |
| $1$ | These proteins are linear,having a thread-like structure. | These proteins have polypeptide chains folded to give a spheroidal shape. |
| $2$ | These proteins are water-insoluble. | These proteins are soluble in water because,during the folding of peptide chains,the hydrophilic groups are pushed outwards,which interact strongly with water. |
| $3$ | The polypeptide chains are held by strong hydrogen bonding. | The hydrogen bonding is comparatively weaker. |
| $4$ | They are stable to changes in $pH$. | They are sensitive to $pH$ changes. |
