Electron and ion spectroscopy of the cyclo-alanine–alanine dipeptide

Physical Chemistry Chemical Physics, 2022
The VUV photoionisation and photofragmentation of cyclo-alanine-alanine (cAA) has been studied in a joint experimental and theoretical work. The photoelectron spectrum and the photoelectronphotoion coincidence (PEPICO) measurements, which enable control of the energy being deposited, combined with quantum chemistry calculations, provide direct insight ...

Targeting Human Endothelial Cells with Glutathione and Alanine Increases the Crossing of a Polypeptide Nanocarrier through a Blood–Brain Barrier Model and Entry to Human Brain Organoids

Cells, 2023
Nanoparticles (NPs) are the focus of research efforts that aim to develop successful drug delivery systems for the brain. Polypeptide nanocarriers are versatile platforms and combine high functionality with good biocompatibility and biodegradability. The

Relationship of fetal alanine uptake and placental alanine metabolism to maternal plasma alanine concentration [PDF]

American Journal of Physiology-Endocrinology and Metabolism, 1998
Uterine and umbilical uptakes of alanine (Ala) were measured in 10 ewes before (control) and during intravenous infusion of Ala, which increased maternal arterial Ala concentration from 115 ± 14 to 629 ± 78 μM ( P < 0.001). In 8 of these ewes, placental Ala fluxes were traced by constant intravenous infusion ofl-[3,3,3-2H3]Ala in the mother andl-[1-

Glutamate Dehydrogenase Is Important for Ammonia Fixation and Amino Acid Homeostasis in Brain During Hyperammonemia

Frontiers in Neuroscience, 2021
Impaired liver function may lead to hyperammonemia and risk for hepatic encephalopathy. In brain, detoxification of ammonia is mediated mainly by glutamine synthetase (GS) in astrocytes.

Infrared Free Electron Laser or Polarized Ultraviolet Photolysis of Hierarchical and Chiral Components of Interleukin-6, AlanylAlanine and Alanine

Trends in Peptide and Protein Sciences, 2021
Interleukin-6 (IL-6) could be decomposed by irradiation of IR-FEL (Infrared free electron laser). Using circularly polarized and other UV light and IR-FEL light, photolysis of hierarchical components of cast films of IL-6, namely deuterated aqueous ...

High Protein Diets Improve Liver Fat and Insulin Sensitivity by Prandial but Not Fasting Glucagon Secretion in Type 2 Diabetes

Frontiers in Nutrition, 2022
Glucagon (GCGN) plays a key role in glucose and amino acid (AA) metabolism by increasing hepatic glucose output. AA strongly stimulate GCGN secretion which regulates hepatic AA degradation by ureagenesis.
