| Globular protein | Fibrous protein |
| 1. Globular protein consists of a polypeptide chain that is folded around itself which gives rise to a spherical structure. | 1. Fibrous protein is a fiber-like structure formed of the polypeptide chain. These proteins are held together by strong disulfide and hydrogen bonds. |
| 2. Soluble in water. | 2. Not soluble in water. |
| 3. All enzymes are globular proteins. Hormones like insulin are globular proteins. | 3. These are used for structural purposes. For instance, collagen is present in tendons, keratin in hair and nails, and myosin in muscles. |
