4-羟苯丙酮酸 4-Hydroxyphenylpyruvic acid
(重定向自Hydroxyphenylpyruvic acid)

4-羟苯丙酮酸 (英语:4-Hydroxyphenylpyruvic acid,4-HPPA)是一种苯丙氨酸的代谢中间产物。苯丙氨酸的侧链被苯丙氨酸羟化酶羟化成为酪氨酸。酪氨酸再由酪氨酸转氨酶转化为4-羟苯丙酮酸。
4-羟苯丙酮酸同时也是伪枝藻素生物合成的前体物质。

![]() 4-Hydroxyphenylpyruvic acid (4-HPPA) is an intermediate in the metabolism of the amino acid phenylalanine. The aromatic side chain of phenylalanine is hydroxylated by the enzyme phenylalanine hydroxylase to form tyrosine. The conversion from tyrosine to 4-HPPA is in turn catalyzed by tyrosine aminotransferase. Additionally, 4-HPPA can be converted to homogentisic acid which is one of the precursors to ochronotic pigment. |
