Water forms hydrogen bonds with proteins. how might these hydrogen bonds alter the ability of a protein to undergo conformational changes in water versus in the gas phase?

Answer and Explanation:

Water is the most important solvent for biomolecules such as proteins because its form very strong and unique hydrogen bonds.

The secondary, tertiary and also quaternary structures of proteins depends on its solvatation (in which the protein is surrounded by water molecules). That means that is very important the interaction between water molecules and aminoacids in the primary sequence of the protein. In water, the protein is stabilized by the effect of the hydrogen bonds. As the conformation of the protein is essential to mantain the protein functionality (e.g. in enzymes, which are proteins that catalize reactions) and to interact to other proteins, its proper hydratation is very important.

Conversely, if the protein is in the gas phase, there are not interactions with water, and there is not stabilization of its conformation. The protein cannot retain its essential structure and functionality.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
