WebPhenylalanine (symbol Phe or F) is an essential α-amino acid with the formula C 9 H 11 NO 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. ... Good sources of phenylalanine are eggs, chicken, liver, beef, milk, ... WebTyrosine can be oxidized to p-hydroxyphenylpyruvic acid, which can in turn form homogentisic acid (5-13). Embden, Salomon, and Schmidt (14) showed that phenylalanine, tyrosine, and homogentisic acid yield acetoacetic acid when perfused through a surviving liver. It has long been known that these amino acids have ketogenic activity in tivo (15-17).
