Techniques for Producing Peptides
Learning about the similarities and differences between peptides and proteins is sure to pique your interest as you progress in your study of organic compounds. Despite their same amino acid composition and the possibility that they perform comparable functions, proteins are notoriously difficult to investigate.
Scientists cannot synthesize a functional protein longer than 200–300 amino acids. Unluckily, the ability to create functioning proteins of any size is vital when comprehending the biological basics of any given organism or cell. You need to be well-versed in the issues plaguing this field and mindful that ignorance may quickly distort facts and lead you to erroneous conclusions.
Differentiating Peptides and Proteins
Firstly, know that peptides are typically shorter than 50 amino acids. Due to its brevity, their structure is often linear or consists of relatively few folds. Therefore, it is straightforward to mass-produce synthetic peptides by simply arranging the amino acids in the correct order and putting the completed product in storage until it is required.
Flexibility and shape change in response to temperature fluctuations are hallmarks of proteins. Even if you synthesize a fully functioning protein in the lab, it may become worthless if the temperature, pH, or other environmental conditions change before you can utilize it.
Some scientists using cellular-based protein manufacturing techniques may be oblivious to these issues. However, if you’ve ever cooked meat or other foods to “denature” particular dangerous proteins, you can readily understand how the same concerns might wreak havoc in a lab.
The protein folding problem
The concept that tiny organelles can produce proteins containing hundreds of molecules in a matter of hours, or even minutes, is sure to pique your interest if you give it some attention. Ribosomes are responsible for more than just ensuring that amino acids are incorporated into the correct sequence; they also guarantee proper protein folding.
Did you know that the loops in one protein molecule may fold into a lock shape that perfectly matches the “key” supplied by another protein? Proteins may serve as transport systems that bind specific molecules at one spot while repelling them in other areas and as the foundation for hormones and other triggering processes.
Challenges in making functional proteins
Try walking a mile instead of riding a bike or driving a vehicle if you haven’t already. Assuming you take the same route, the only difference in result will be in the time it takes you to complete your mission. It is possible to coax cells into producing proteins they usually wouldn’t in the lab, allowing for the creation of functional proteins that cells wouldn’t make in their natural environment.
Although there is considerable success in replicating viral behavior, this approach still leaves many unanswered issues concerning protein synthesis. For proteins, in particular, scientists have had a hard time, if not wholly failed, at recreating their precise folds. Furthermore, even when all the folds are correctly replicated, the protein molecule may suddenly come apart or denature in settings when it should stay stable.
Indications for the importance of developing synthetic functional proteins
The world is suffering from a lack of knowledge about the inner workings of biological beings, and you don’t need to read the news to see it. This includes failing to investigate the cause of the alarming decline of bee and fish populations and the inability to rein in the alarming growth of cancer.
Many scientists now look to molecular biology and “genetics” for explanations. Researchers will have difficulty generating reliable data and answers to a wide range of issues until we can synthesize proteins as efficiently and reliably as peptides.
