Explain how proteins are formed using the concept of polymerization. How do RNA and magnetic beads bind together when performing RNA extraction? Why does DNA use deoxyribose while RNA uses ribose? Explain how the protein secondary structure is charact...
一些化学问题(英文版)1.Ionic compounds have very high melting points.Explain at least two forces that cause this physical characteristic.2.List bonds in order of bond strengtha.Hydrogen bond between H2Ob.Covalent bond between H and O in w
Explain briefly how substances with ionic bonding differ in properties from substances with covalent bonding. Describe, using valence bond theory, the bonding in CO using hybrid orbitals. Explain vividly how hydrogen bonds are formed and what force keeps the bonds int...
Bonding interface tilting has been observed to be associated with changes in the number of hydrogen bonds bridging the TCR and pMHC molecules as they were pulled to unbind in SMD simulations6. Therefore, we investigated whether, and if so, how well the tilting angle would correlate with the ch...
How are these formed and how do they work ? Explain in detail when a metal reacts with an acid, hydrogen gas is usually produced. Explain the process of synthesizing copper(II) hydroxide from the solution of sodium hydroxide. Explain what is a fossil fuel and its formation? Explain the ...
[50] showed that the extent of protein under-wrapping, which indicates the solvent accessibility to backbone hydrogen bonds, is negatively correlated with gene duplicability in Escherichia coli, yeast, worm, fly, human, and Arabidopsis thaliana. They also found that the correlation becomes weaker ...
Carbohydrates are the group of organic compounds in living tissues and food sources as starch, cellulose, and sugars. The proportion of oxygen and hydrogen in carbohydrates is equivalent to the proportion in water that is 2:1. Carbohydrates can be further, divided into two types: simple ...
Although most of the ice found on Earth has a hexagonal structure (think of snowflakes), ice can take on at least 20 different crystalline and amorphous forms. This curious behaviour comes in part from the weak intermolecular bonds between its two hydrogen atoms, which are separated by ...
Graphenes, potentially, could help to make fuel-cell cars running on hydrogen a more viable prospect. [14]On the other hand, if you pepper tiny holes into graphene to make it porous, you get make a meshlike material called holey graphene that can work like an electrical semiconductor or a...
Why are hydrogen bonds so important in explaining the properties of water? Why do liquids take the shape of their container? Why is the Earth's inner core solid and the outer core liquid? Why does basaltic magma have the lowest viscosity?
