Why are the side chains of amino acids so important? (Select all that apply.) OThey function as a biochemical "tool belt" which determines what the protein can do. OThey break off to function as signaling molecules. OAntibodies use them to stab pathogens. O They interact with each other to help the protein fold and remain folded. OThey're not really important. All 20 amino acids are pretty similar in their properties. O Enzymes transfer them to substrates to create products. O They're what the digestive system removes to use as vitamins.

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.
