应用


  • Enhanced protein-metabolite correlation analysis: To investigate the association between Staphylococcus aureus mastitis and metabolic immune pathways.: This article discusses the metabolic pathways associated with bacterial infections in livestock, potentially useful for chemists studying metabolic pathways and their linkage to immune responses (Chen et al., 2024).

  • Probing pharmaceutically important amino acids L-isoleucine and L-tyrosine Solubilities: Unraveling the solvation thermodynamics in diverse mixed solvent systems.: This study explores the solubility and solvation thermodynamics of l-isoleucine, providing critical data for chemists working with pharmaceutical formulations and solubility studies (Chakraborty et al., 2024).

The cerebral circulation is supplied with two vasodilator systems: the parasympathetic system storing vasoactive intestinal peptide, peptide histidine isoleucine, acetylcholine and in a subpopulation of nerves neuropeptide Y, and the sensory system, mainly originating in the trigeminal ganglion, storing substance

BCAAs (leucine, isoleucine, and valine), particularly leucine, have anabolic effects on protein metabolism by increasing the rate of protein synthesis and decreasing the rate of protein degradation in resting human muscle. Also, during recovery from endurance exercise, BCAAs were found

Long-term physical inactivity seems to cause many health problems. We studied whether persistent physical activity compared with inactivity has a global effect on serum metabolome toward reduced cardiometabolic disease risk. Sixteen same-sex twin pairs (mean age, 60 years) were selected

Previously, we determined the crystal structures of the dimeric ligand binding region of the metabotropic glutamate receptor subtype 1. Each protomer binds l-glutamate within the crevice between the LB1 and LB2 domains. We proposed that the two different conformations of
