Phenylalanine (symbol Phe or F) is an essential α-amino acid with the formula C 9H 11NO 2. It can be viewed as a benzyl group substituted for the methyl group of alanine, or a phenyl group in place of a terminal hydrogen of alanine. This essential amino acid is classified as neutral, and nonpolar because of the inert and hydrophobic nature of the benzyl side chain. The L-isomer is used to bioche… WebPhenylalanine (being an amino acid) should be able to be made more soluble in either a basic or acidic environment where it would form as the anionic or cationic part of a salt respectively (essentially this means it should be able to act as either a base or an acid to form a salt, making it a positively or negatively charged molecule … healthy crock pot recipes easy https://druidamusic.com
