BIOMOLECULES AND ENZYMES

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: -Amino Acid Solubility in Water As presented in Figures 1–3, amino acid solubilities in water are modeled, including l-tyrosine, l-leucine, l-aspartic acid, l-tryptophan, l-glutamic acid, l-alanine, dl-alanine, dl-valine, l-phenylalanine, dl-serine, l-proline, l-serine, and glycine.

Detailed explanation-3: -Answer and Explanation: The amino acid that is least soluble in water is phenylalanine.

Detailed explanation-4: -Lipid Functions Fat-soluble substances, when transported by lipids, become more accessible and effectively absorbed in the intestines. With the exception of phospholipids, lipids are insoluble in water, while amino acids are soluble in water.

Detailed explanation-5: -Glutamate is the amino acid most soluble in water. Glutamate is the most soluble in water because all the amino acids are usually transaminated to glutamate and therefore undergo deamination.
