Web• Water is a participant in many biochemical reactions.One of the most common biological reactions is cleavage of a chemical bond by water (hydrolysis) as observed in the initial steps of digestion of proteins, carbohydrates, and nucleic acids.Water is also a principal reactant in the photosynthesis process: WebA word of caution when choosing the appropriate experiment involves the location of the salt bridge within the protein. The environment plays a large role in the interaction. [14] At high ionic strengths, the salt bridge can be completely masked since an electrostatic interaction is involved.
WebHigh levels of salt interact with a large portion of the water dipoles, thus decreasing the number of interactions of the protein with water. Reducing the ionic concentration in the protein solution allows charged groups on the proteins to interact more readily with the water solvent molecules. Submit .
