Phenylalanine ball and stick model spinning. Phenylalanine (symbol Phe or F) [3] 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.
2-Amino-3-phenyl-propanoic acid Abbreviations: F, Phe Synonyms: alpha-Amino-beta-phenylpropionic acid ... (phenylalanine) ^a CID 994 from PubChem (phenylalanine)
The enzyme phenylalanine ammonia lyase (EC 4.3.1.24) catalyzes the conversion of L-phenylalanine to ammonia and trans-cinnamic acid.: [1] L -phenylalanine = trans -cinnamate + NH 3 Phenylalanine ammonia lyase (PAL) is the first and committed step in the phenyl propanoid pathway and is therefore involved in the biosynthesis of the polyphenol ...
Most common among natural products is the amino acid phenylalanine, which contains a phenyl group. A major product of the petrochemical industry is " BTX " consisting of benzene, toluene, and xylene - all of which are building blocks for phenyl compounds.
Since the proteins have acidic and basic regions, they can serve as both proton donors or acceptors in order to maintain a relatively stable intracellular pH. In the case of a phosphate buffer, substantial quantities of weak acid and conjugate weak base (H 2 PO 4 – and HPO 4 2– ) can accept or donate protons accordingly in order to conserve ...
Absence of this enzyme allows the buildup of phenylalanine, which can lead to mental retardation. Genetic engineering – taking a gene from one organism and placing it into another. Biochemists inserted the gene for human insulin into bacteria. The bacteria, through the process of translation, create human insulin.
In mammals it is created from -lactate and L-phenylalanine by the cytosol nonspecific dipeptidase (CNDP2) protein. [1] It is classified as N-acyl-alpha-amino acid and pseudodipeptide. [11] It has also been reported that as an additive, N-L-lactoyl phenylalanine improves the taste of food, conferring an umami flavor. [12]
Organotrophs use organic compounds as electron/hydrogen donors. Lithotrophs use inorganic compounds as electron/hydrogen donors.. The electrons or hydrogen atoms from reducing equivalents (electron donors) are needed by both phototrophs and chemotrophs in reduction-oxidation reactions that transfer energy in the anabolic processes of ATP synthesis (in heterotrophs) or biosynthesis (in autotrophs).
