Hypoxanthine as a Measurement of Hypoxia [PDF]

Pediatric Research, 1975
The hypoxanthine concentration in plasma was found to be a sensitive parameter of hypoxia of the fetus and the newborn infant. The plasma level of hypoxanthine in the umbilical cord in 29 newborn infants with normal delivery varied between 0 and 11.0 mumol/liter with a mean of 5.8 mumol/liter, SD 3.0 mumol/liter.

Bacillus Subtilis 29784 as a Feed Additive for Broilers Shifts the Intestinal Microbial Composition and Supports the Production of Hypoxanthine and Nicotinic Acid

Animals, 2021
The probiotic Bacillus subtilis strain 29784 (Bs29784) has been shown to improve performance in broilers. In this study, we used a metabolomic and 16S rRNA gene sequencing approach to evaluate effects of Bs29874 in the broiler intestine.

Label-Free ZnIn₂S₄/UiO-66-NH₂ Modified Glassy Carbon Electrode for Electrochemically Assessing Fish Freshness by Monitoring Xanthine and Hypoxanthine

Chemosensors, 2022
Considering that simultaneous detection of xanthine (XA) and hypoxanthine (HXA) has been proved to be a reliable and feasible method for assessing fish freshness, a novel electrochemical sensing platform based on the ZnIn2S4/UiO-66-NH2 modified glassy ...

Ammonification Process Is Limited by Transformation of Medium Molecular Weight Nitrogenous Organics but Not Hydrolysis of Proteins. [PDF]

Adv Sci (Weinh)
A multi‐level analytical framework, integrating protein‐level persistence analysis, nontargeted HRMS formula tracking, peptide‐level proteomics, and targeted monomer quantification under varying redox conditions, together with FMO calculations reveal that ammonification is limited by medium molecular weight nitrogenous multimers.

Nitrogen Metabolism in Non-Nodulated and Nodulated Soybean Plants Related to Ureide Synthesis

Nitrogen, 2023
Soybean plants can fix atmospheric N2 in the root nodule, a symbiotic organ with rhizobia. The primary forms of N transported from N2 fixation are ureides, allantoate, and allantoin, supplemented with asparagine.

Hypoxanthine Induces Muscular ATP Depletion and Fatigue via UCP2

Frontiers in Physiology, 2021
Hypoxanthine (Hx), an intermediate metabolite of the purine metabolism pathway which is dramatically increased in blood and skeletal muscle during muscle contraction and metabolism, is characterized as a marker of exercise exhaustion.
