Types of Proteins:

• Globular Proteins:
• Compact, spherical proteins that are typically soluble in water.
• Examples include enzymes and antibodies.
• Their structure makes them well-suited for catalysis and transport roles within the body.

• Fibrous Proteins:
• Long, thread-like proteins that are insoluble in water.
• They provide structural support due to their stable, elongated shape.
• Examples include keratin (in hair and nails) and collagen (in connective tissues), which form strong fibres for support and stability.

The specific structure of each protein type directly influences its function, with globular proteins being flexible and suited to dynamic roles, while fibrous proteins offer durability and strength for structural support.
