Question

What are some examples of functional and structural proteins?

Answer 1

Hint: Protein is an example of a macronutrient that is needed for the normal growth of the body. Calories, or energy, are provided by macronutrients.

Complete answer:
Proteins that are fibrous and stringy are known as structural proteins. They are the most common form of protein found in nature. Their primary purpose is to provide mechanical assistance. One or more forms of protein structures can be found in globular and fibrous proteins. Proteins are categorized into four structural levels: primary, secondary, tertiary, and quaternary.

Structural proteins, like bones, keep cells in shape and make up structural components in connective tissues such as cartilage and bone in vertebrates. Enzymes are a different type of protein that catalyze the biochemical processes that take place in cells.

Keratin, collagen, and elastin are examples of structural proteins. Skin, quills, feathers, horns, and beaks all contain keratins. Connective tissues, such as tendons and ligaments, contain collagen and elastin. Collagen is the most common protein present in mammals.

Functional proteins are biologically active proteins that help to maintain and support normal immune function. Unlike structural proteins, which create structures, functional proteins perform a role in the body (e.g., bones and muscles). Avidin, a protein found in egg whites, is an example of a functional protein. This biotin-binding protein has a high degree of specificity and tenacity.

Some examples of functional proteins in humans are:- for transport- haemoglobin, as hormones- Insulin and thyroxine, for protection we have immunoglobulin and fibrinogen, for communication we have neurotransmitters etc.

Note: Protein aids in the repair and regeneration of our body's tissues, as well as the facilitation of metabolic reactions and the coordination of bodily functions. Proteins not only provide a structural structure for your body, but they also help to maintain proper fluid balance.
