Learning Outcomes:
i. Define globular and fibrous proteins.
ii. Explain the difference between globular and fibrous proteins in terms of their structure and function.
iii. Identify examples of globular and fibrous proteins.
What are globular and fibrous proteins?
Proteins can be classified into two main types: globular and fibrous proteins. Globular proteins are rounded and compact in shape. Fibrous proteins are long and thread-like in shape.
What is the difference between globular and fibrous proteins in terms of their structure and function?
Globular proteins are soluble in water, while fibrous proteins are insoluble in water. This is because globular proteins have a hydrophilic (water-loving) surface, while fibrous proteins have a hydrophobic (water-hating) surface. Globular proteins are often involved in metabolic reactions, such as enzymes and hormones. Fibrous proteins are often used to provide structural support, such as collagen and keratin.
What are some examples of globular and fibrous proteins?
Examples of globular proteins include enzymes, hormones, antibodies, transport proteins, and storage proteins. Examples of fibrous proteins include collagen, keratin, elastin, and myosin.
