Proteins are essential biomolecules with diverse roles in the body. Here are five key uses:
-
Structural Support: Proteins provide the framework for cells and tissues. Collagen, for example, is a major structural protein in skin, bones, and cartilage. [Reference: Proteins serve as structural support... 14-Nov-2022]
-
Enzymes & Biochemical Catalysts: Many proteins act as enzymes, speeding up biochemical reactions vital for life. These reactions include digestion, energy production, and DNA replication.

-
Hormones: Some proteins function as hormones, chemical messengers that regulate various bodily processes. Insulin, a protein hormone, controls blood sugar levels. [Reference: Proteins serve as hormones... 14-Nov-2022; Acts as a Messenger - https://www.healthline.com/nutrition/functions-of-protein]
-
Building Blocks for Tissues and Muscles: Proteins are crucial for building and repairing tissues, including muscles, skin, and organs. Dietary protein provides the amino acids needed for this process.

-
Cellular Processes & Initiators of Cellular Death: Proteins are involved in a wide range of cellular processes, including cell signaling, transport, and immune responses. They also play roles in programmed cell death (apoptosis). [Reference: Proteins serve as initiators of cellular death... 14-Nov-2022]
