Lysine sulfate in compound feed for laying hens and the effectiveness of its use

Kormlenie sel'skohozjajstvennyh zhivotnyh i kormoproizvodstvo (Feeding of agricultural animals and feed production), 2022
Lysine of feed proteins is incorporated into tissue proteins without any preliminary changes. It is an indispensable precursor in the synthesis of collagen, participates in the formation of carnitine, which plays an important role in fat metabolism. Lysine activates hematopoiesis, promotes calcium absorption, and has a benefi cial eff ect on protein ...

Influence of the sulfation degree of glycosaminoglycans on their multilayer assembly with poly-l-lysine

Colloids and Surfaces B: Biointerfaces, 2016
We report on the build-up and the intrinsic properties of polyelectrolyte multilayer films from poly-l-lysine and glycosaminoglycans (GAGs) with different sulfation degree, i.e. different charge. We used three complementary techniques, namely electrokinetic analysis (EKA), quartz-crystal microbalance with dissipation (QCM-D) and surface plasmon ...

Isolation of sulfated glycoproteins from human gastric juice with lysine-Sepharose

Analytical Biochemistry, 1981
Abstract A procedure for the isolation of sulfated glycoproteins from human gastric juice is described. Sulfated glycoproteins are adsorbed on lysine-Sepharose at pH 2.0, where only the sulfate group of glycoproteins carries a negative charge. The method is simple and rapid, and moreover, the recovery of sulfate is excellent.

Fibrous Assemblies and Water Gelation in Mixtures of Lysine with Sodium Alkyl Sulfates

Langmuir, 2005
Thermoresponsive, pH-sensitive fibrous structures and gels are formed in aqueous mixtures of the amino acid lysine with oppositely charged sodium alkyl sulfate surfactants. The formation of these assemblies depends on the chain length of the surfactant, which is varied between 8 and 16, the chirality and degree of protonation of the amino acid, and the

Fractionation and Isolation of Heparan Sulfates Using Poly-l-Lysine-Sepharose

Analytical Biochemistry, 1984
A simple procedure for the isolation of heparan sulfates from pig lung using a poly-L-lysine-Sepharose column is described. Glycosaminoglycans are absorbed on poly-L-lysine-Sepharose at pH 7.5 and eluted with an NaCl linear gradient in the following order: hyaluronic acid (0.32 M NaCl), chondroitin (0.36 M NaCl), keratan sulfate (0.80 M NaCl ...

Effects of Moisture and Particle Size Distribution on Flame Propagation of L-Lysine Sulfate Powder

Journal of Loss Prevention in the Process Industries, 2020
Abstract Lysine is an essential amino acid for human body, and lysine sulfates are at risk of fire and explosion during the production and processing. However, there is no public report on the lysine sulfate powder explosion hazard research. In this paper, the effects of moisture, mass concentration and particle size on the flame propagation ...

Assessing the bioavailability of l-lysine sulfate compared to l-lysine HCl in rainbow trout (Oncorhynchus mykiss)

Aquaculture, 2015
Abstract A growth trial was conducted to determine relative bioavailability between two commercially available sources of supplemental lysine in rainbow trout. A basal diet, which was formulated to be deficient in lysine while meeting all other known nutritional requirements for rainbow trout was supplemented with increasing levels (0.1, 0.2, 0.4 & 0.

Influence of dietary lysine on the utilization of zinc from zinc sulfate and a zinc-lysine complex by young pigs.

Journal of Animal Science, 1998
We conducted two trials (n = 144 and 96) to evaluate the response of feeding either ZnSO4 x H2O or a zinc-lysine complex (ZnLys) in combination with various lysine levels on growth performance, liver, kidney, and 10th rib Zn concentration, serum Zn humoral immune response and absorption of Zn (chromic oxide method) of young pigs.

Bioavailability of feed-grade copper sources (oxide, sulfate, or lysine) in growing cattle

Journal of Animal Science, 1994
Plasma Cu concentrations and ceruloplasmin (a Cu metalloenzyme) activity were used to assess relative Cu bioavailability from different Cu sources for growing cattle. In Exp. 1, 18 calves (average BW 207 +/- 7.7 kg) that had been fed Cu-deficient diets since birth were randomly assigned to treatment.

Interactions between chondroitin sulfate C and poly-L-lysine: Preliminary report

Biochemical and Biophysical Research Communications, 1972
Abstract Ionic interactions occur between chondroitin sulfate C and poly- L -lysine in dilute aqueous solution which force the polypeptide to adopt the α-helical conformation rather than the ‘charged coil’ form expected at neutral pH in the absence of the polysaccharide.
