Understanding Proteins: Essential Functions and Importance for the Human Body
This session explains proteins, their composition of amino acids, and their crucial roles in the body including structural support, enzymatic activity, immune defense, transport functions, and hormonal signaling. It highlights proteins' necessity for growth, repair, and maintenance of tissues.
what is protein?
Proteins are large, complex molecules essential for the body's structure, function, and regulation of tissues and organs1(https://medlineplus.gov/genetics/understanding/howgeneswork/protein/). They are composed of long chains of amino acids, of which there are 20 different types. The sequence of these amino acids determines each protein’s unique structure and function.
Proteins serve various crucial functions, such as:
- Structural Components: Provide support and shape to cells and tissues.
- Enzymes: Catalyze biochemical reactions, making them occur more efficiently.
- Antibodies: Bind to foreign particles to protect the body against infections.
- Transport/Storage: Carry atoms and small molecules within cells and throughout the body.
- Messengers: Transmit signals to regulate biological processes (e.g., hormones like insulin).
Besides their functional roles, proteins are necessary for growth, repair, and maintenance of tissues2(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3905294/).
