Biophysics and protein dynamics Literature Review Essay

Biophysics and protein dynamics have shaped our lives when it comes down to advancements in medicine. In living cells, proteins are the main components that keep the organism running at its best with every single protein and enzyme having their own function. The discovery of DNA, RNA, and other protein synthesis became the structures of life in a new perspective in the smallest ways leading to the continuing studies to uncover more.

Scientists have come across multiple techniques in which created treatments to the illnesses humans have dealt and may have to deal with. Accordingly, biophysics is the conceptual portion of protein dynamics to what is known and is yet to be known. Science is a term merely stating the broad foundation that defines living organisms to how the atmosphere responds. To understand these more in depth we focus on certain branches and scientists continue to do so because we live in a complex world that keeps changing.

Among these studies scientists are able to state that there are small existing worlds that form our world with the work of biophysics—the application of physics onto the world of biology—significantly seen in protein dynamics. Protein dynamics is of great importance when it comes to the human health, to know how proteins work and the ability to structure them for our benefit can lead to remarkable advances not only in the medical field but also in the sciences as a whole. Physics is the leading character in the daily life of the individual.

As we sleep the normal force of the bed is holding our body in place to rest while gravity makes sure our body does not float away and wake up in an unknown place. The same forces affect the smallest particle, in this case proteins, on Earth the majority of the time by the statistical mechanics, which involves the use of work, heat, free energy and entropy. Proteins are complex particles that make an organism’s genetic makeup, all having their own dynamic function. The study in this subject has been under experiment ince 1838 only seen as organic compounds that are good source for the nutrition of species. Since then different discoveries were made, from the isolation and crystallization of enzymes to the three-dimensional structures of haemoglobin and myogloblin. We have come to understand that “proteins do everything in the living cells. All functions of the living organisms are related with proteins. Each protein or groups of proteins are responsible for their own specific function. That is why in bacterial cells, proteins make about a half of the dry weight of cells” (United Ltd Par 8).

The beauty of biophysics and the protein dynamics working as one is that both subjects inspire each other. In the Medill Reports News from Chicago it stated that a newly found protein study technique could help medics detect cancer before it is developed. With the use of listening to the waves found in a teardrop containing a protein. “That a protein in our tears has anti-bacterial properties has long been known. But this is the first time it has been studied using this technique” (Vaidya Par 3).

Physics and astronomy researcher, Professor Philip Collins, used the method of circuits onto the transistors at the molecular-level to observe the route each protein is taking in the cell. Collins, along with other researchers of the institute, affirmed that they have learned a lot just by listening to it for an entire afternoon. “Researchers dropped food into the transistor plus enzyme, called a nanocircuit, and by listening to the protein learned that lysozyme eats continuously without pausing. This is important because it means that lysozyme cuts very big holes when it destroys bacteria,’ Weiss said. He added that researchers also learned how many steps it takes for lysozyme to chew. He said the pattern was as though the lysozyme was eating rows of corn on the cob. ” (Vaidya Par 7). This is as far as scientists have come to understanding the dynamics of proteins such as those of enzymes, hormones, antibodies, receptors, also the signaling, storage, structural, motor and transport proteins, that will continue to aid human life to overcome new developments in diseases.

A great astrophysicist, Carl Sagan, stated that for the grain of salt to be comprehended completely we must know the three-dimensional positions of the atoms and the forces that keep them in their formation. On top of that he mentioned that our brain is capable of knowing 1014 things but it is only one percent of the information of the speck of salt. Just like the grain of salt, scientists have not retained all the information about proteins and now what remains is for researchers to find new techniques and discoveries. Its possibilities are infinite.
