AbstractA series of sequential polypeptides, (Lysi‐Alaj)n, and random copolypeptides, (Lysx, Alay)n, were synthesized. The competitive effect of Ala, a helix former, and Lys, whose homopolymer has a β‐form in neutral NaDodSO4 solution, was determined by CD and absorption spectroscopy.

Protective effects of zinc sulfate and l-lysine on acute ethanol toxicity in mice
Environmental Research, 1979Abstract Survival rates were determined in three groups of male CF-1 mice, treated ip with single and multiple doses of zinc sulfate and/or l -lysine, each alone and in combination, followed by administration of an acute toxic dose of ethanol 1 hr post-treatment. Significant protective effects were observed in all pretreated groups. Zinc and lysine (

AbstractCircular dichroism spectra have been obtained for tri(L‐lysine), tetra(L‐lysine), and penta(L‐lysine) in aqueous sodium dodecyl sulfate at 25°C. None of the oligomers are affected significantly by sodium dodecyl sulfate at detergent concentrations exceeding 0.01 M.

Growth and internal bias field of l-lysine-doped triglycine sulfate (LLysTGS)
Journal of Crystal Growth, 2007Abstract Single crystals of l -lysine-doped TGS (LLysTGS) have been prepared from the aqueous solutions with various concentrations of dopant. The variation of crystal shape and the distribution of internal bias field E b were examined. The growth rate in the + b side of seed crystal is higher than in the − b side.

Evaluation of copper sulfate and a copper lysine complex as growth promoters for weanling swine.
Journal of Animal Science, 1995Two 5-wk trials using 176 weanling pigs (average initial weight of 8.3 kg and age of 31 d) were conducted to examine the effect of feeding varying levels of dietary Cu from copper sulfate (CuSO4) or a copper lysine complex (CuLys) on performance, mineral stores, serum copper, and serum mitogenic activity.

Surface properties of mixed solutions of poly-l-lysine and sodium dodecyl sulfate
Journal of Colloid and Interface Science, 1978Abstract Equilibrium surface tension measurements have been carried out on mixed solutions of poly l -lysine hydrobromide and sodium dodecyl sulfate. A strong synergistic lowering of the surface tension was found at concentrations below the point at which precipitation, micellization, or complex formation in solution occurred.

Interaction between poly(
AbstractIonic polymer‐polymer interaction was studied in aqueous solution for poly(L‐lysine) (PLL) and sulfated poly(vinyl alcohol) (PVS) as functions of pH, the degree of sulfation, the functional unit mole ratio of the two polymers and temperature by means of circular dichroism and viscosity measurements.

Interaction of sodium dodecyl sulfate with poly(
AbstractThe interactions between a homopolypeptide, poly(L‐lysine) [(Lys)n], and an anionic surfactant, sodium dodecyl sulfate (NaDodSO4), were studied by 13C NMR spectroscopy in D2O solution. By observing the chemical shift of the ε‐amino carbon of lysine monomer in D2O solution at pH 7,3 in presence and absence of NaDodSO4, direct evidence was found ...

Quasi-elastic laser light scattering studies have shown that large multimolecular aggregates are formed on mixing dilute aqueous solutions of poly(L-lysine) and chondroitin 6-sulfate. For the two components in equimolar residue proportions at a total concentration of 0.178 mg/mL, the aggregates have hydrodynamic radii of 1200 A.

Glycyl-L-histidyl-L-lysine-copper (II) complex (GHK-Cu) is a naturally occurring tripeptide with potential healing properties. We studied the effect of GHK-Cu on the synthesis of glycosaminoglycans (GAGs) by normal human fibroblasts in culture.
