Phenylalanineis anessential amino acid. It is normally degraded via thetyrosinepathway. To enter the tyrosine pathway,phenylalanineis converted into tyrosine by theenzymephenylalanine hydroxylase, which hastetrahydrobiopterinas a cofactor. Deficiency of the enzyme or of its cofactor causes accumulation ofphe...

Phenylalanine-free infant formula is an essential source of safe protein in a phenylalanine restricted diet, but its efficacy is rarely studied. We report a multicentre, open, longitudinal, prospective intervention study on a phenylalanine-free infant fo
These results suggest that buried F26 is essential for maintaining the active-site conformation of SpTrx as an oxidoreductase and its structural stability for interactions with SpTR at colder temperatures. 展开 关键词: PSYCHROPHILIC bacteria STRUCTURAL stability THIOREDOXIN SPHINGOMONAS PROTEIN folding ...

Pharmacokinetics D-Phenylalanine is the synthetic dextro isomer of phenylalanine, an essential amino acid with anti-depressant and analgesic activities. D-Phenylalanine is converted into tyrosine and tyrosine in turn is converted into L-dopa, norepinephrine, and epinephrine, three key neurotransmitters. As...

Aspartame is an artificial sweetener used in many low-calorie foods, while phenylalanine is an essential amino acid found naturally in protein-rich foods and also a component of aspartame.
Moreover, LmPAH appear to be non-essential for the growth of L. major in vitro (26) indicating that there must be other crucial pterin-dependent processes within these parasites. Whatever the role(s) of H4B within these parasites may be, L. major also harbor a putative PCD and a well...
