There have been substantial advances in the application of molecular modelling and simulation to drug discovery in recent years, as massive increases in computer power are coupled with continued development in the underlying methods and understanding of how to apply them. Here, we survey recent advanc...
Consuming ultra-processed foods that are typically high in salt, sugar, and fat—and cheap and accessible—may boost the risk of heart disease, diabetes, anxiety, depression, and cognitive decline.
for measuring and comparing relative molecular flux rates of different biological molecules by administering isotope-labeled water to one or more tissues or individuals and comparing the molecular flux rates of two or more biological molecules, including biological molecules in different chemical classes. ...
Compare and contrast glycogen and fat as energy storage molecules. How does the chemical structure of carbohydrates and cellulose (or fiber) differ? How do we benefit from each of these molecules? How do they impact our health and ability to function? How does our body process these molecules...
diffusible molecules called autoinducers. When the cell population reaches a critical threshold (a quorum), these autoinducers initiate a cascade of reactions that activate genes associated with cellular functions that are beneficial only when the population reaches a critical density. For example, in ...
Explain why in gaseous reaction the collision frequency between molecules is far greater than the rate at which molecules react. Compare and contrast the ease with which molecules are able to move relative to each other in the three states of matter. ...
molecules may have enough energy to escape from the liquid and begin to rise into the atmosphere as a vapor. As the vapor rises higher and higher, the temperature of the surrounding air becomes lower and lower. Eventually, the vapor loses enough heat to the surrounding air to allow it to ...
That kind of computation would be impossible for a person to do using pen and paper, or even a simpler computer program, because there are so many variables within the millions of molecules, proteins and genes that are working together in the human body. To create the kinds of solutions tha...
What are the differences between organic and inorganic substances/molecules? Compare and contrast pepsin and trypsin. HIV is a retrovirus. Describe how a retrovirus is different from other viruses. What are the functions of mRNA, tRNA, and rRNA? How are the three muscle types alike in structure...
The IPCC says that the pre-industrial amount of CO2 in the Earth's atmosphere was about 280 parts per million (ppm), meaning that for every million molecules of dry air, 280 of them were CO2. In contrast, 2005 levels of CO2 were measured at 379 ppm [Source: IPCC]. Nitrous oxide (N2...
