Classify the following proteins into fibrous and globular proteins. insulin, fibroin, myosin, collagen

Explanation

To classify the proteins insulin, fibroin, myosin, and collagen into fibrous and globular proteins, we can follow these steps:

### Step 1: Understand the Definitions
- **Fibrous Proteins**: These proteins are generally elongated and insoluble in water. They are structural proteins that provide support and strength. Examples include collagen and keratin.
- **Globular Proteins**: These proteins are more spherical in shape and are usually soluble in water. They play various roles in biological processes, such as enzymes and hormones. Insulin is a common example.

### Step 2: Analyze Each Protein
1. **Insulin**:
