Thermo-Acoustic Investigation of Molecular Interactions in Aqueous Solutions of L-Histidine at Different Temperatures
Abstract: The present study investigates the acoustic and thermodynamic behavior of aqueous solutions of L-Histidine across a concentration range of 0.01 m to 0.1 m and temperatures varying from 293.15 K to 318.15 K in 5 K intervals. Ultrasonic velocity (μ), density (ρ), and viscosity (η) measurements wereconducted with high precision to understand the solution behavior under different thermal conditions.Temperature constancy during measurements was ensured using a refrigerated circulatory bath withwater …

Preparation of Beta Lactam Compounds and Study of Thermodynamically Behavior
Abstract: Several Lactam derivatives have been prepared by condensation reaction of folic acid with (4-chloroacetophenone and 4-hydroxyacetophenone) in ethanol. Then the resultant compounds (1,2) react with another Schiff bases by reacting of 4- bromobenzaldehyde with an amino acid (Phenylalanine, Tryptophan, Tyrosine and Histidine) to give bis-β-lactam rings. The structures of target compounds were characterized by many spectroscopic methods including NMR, FTIR technique and their melting points. The β- lactam derivatives were …

Purification of Plasmodium Recombinant Protein
Abstract: Malaria is a protozoan disease, caused by parasite plasmodium. There are several species of plasmodium like as P. vivax, P. Ovule, P. Falciparum. It is globally spreaded disease. In 2017, there were an estimated 219 million cases of malaria in 87 countries & deaths stood at 435 000 (WHO.Which protein we purified, we only knew the sequence. So if we could know the function of the protein then we can …
