Synthesis and properties of Poly(L-lactide)-b-poly (L-phenylalanine) hybrid copolymers [PDF]
Hybrid materials constituted by peptides and synthetic polymers have nowadays a great interest since they can combine the properties and functions of each constitutive block, being also possible to modify the final characteristics by using different ...

Two experiments were done to determine the influence of Phe imbalance and excess on Phe-pyruvate aminotransferase (PAT) activity in the chick. Five replicates of 3 chicks (experiment 1) or 2 chicks (experiment 2) of a commercial brown egg layer strain were fed a semipurified diet for 1 wk and then received experimental diets for 10 d.

An isotope dilution model for partitioning of phenylalanine and tyrosine uptake by the liver of lactating dairy cows [PDF]
An isotope dilution model to describe the partitioning of phenylalanine (PHE) and tyrosine (TYR) in the bovine liver was developed. The model comprises four intracellular and six extracellular pools and various flows connecting these pools and external ...
