Detailed explanation-1: -Amino acids are generally soluble in water and insoluble in non-polar organic solvents such as hydrocarbons. This again reflects the presence of the zwitterions. In water, the ionic attractions between the ions in the solid amino acid are replaced by strong attractions between polar water molecules and the zwitterions.
Detailed explanation-2: -Hydrophobic amino acids are those with side-chains that do not like to reside in an aqueous (i.e. water) environment. For this reason, one generally finds these amino acids buried within the hydrophobic core of the protein, or within the lipid portion of the membrane.
Detailed explanation-3: -The hydrophilic amino acids interact more strongly with water (which is polar) than do the hydrophobic amino acids. The interactions of the amino acids within the aqueous environment result in a specific protein shape.
Detailed explanation-4: -Hydrophilic means “water loving, ” and hydrophilic molecules are receptive to water and are likewise in the polar group of molecules. Hydrophilic molecules can bind with water, and thus they make up substances that can dissolve in water.
