Proteins
We generally tend to think of proteins only from a dietary lens, as a component of what we eat. However, they are among the most important and abundant organic macromolecules in the human body, with diverse structures and functions. Every cell contains thousands and thousands of proteins, each with specific functions. Some help in the formation of cellular membrane or walls, some help the cell to move, others act as messages or signals and flow seamlessly from one cell to another, carrying information.
Protein Expression
The method by which living organisms synthesize proteins and further modify and regulate them is called protein expression. Protein expression plays a significant role in several types of research and is highly utilized in molecular biology, biochemistry, and protein research laboratories.
![**How do detergents solubilize membrane proteins?**
This question highlights the role of detergents in the study of membrane proteins. Detergents are amphipathic molecules, meaning they contain both hydrophobic and hydrophilic regions, which allows them to interact with the lipid bilayer of membranes.
In the context of membrane proteins, detergents disrupt the lipid bilayer, allowing the proteins to dissolve in water. This process involves the detergent molecules surrounding the hydrophobic regions of the protein, thereby shielding them from the aqueous environment. As a result, the protein-detergent complexes remain soluble and stable in solution, facilitating further analysis and research.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6ef311ec-f716-453e-a156-2647b8ffb12a%2F003ec458-43f2-46b5-9273-bc2bcaebb851%2Fmm2l3so_processed.jpeg&w=3840&q=75)
