The conversion of citrulline to arginine in kidney [PDF]

, 1941
Glycocyamine is formed in the kidney by the transfer of the amidine group of arginine to the nitrogen atom of glycine. In the study of this reaction it was observed that glycocyamine was also formed from citrulline and glycine.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

Advanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

Effect of nitrous oxide on folate coenzyme distribution and de novo synthesis of thymidylate in human bone marrow cells [PDF]

, 1992
The effect of nitrous oxide on intracellular folate metabolism of the human bone marrow was studied in vitro. Bone marrow cells, obtained from healthy volunteers, were incubated with 5 × 10−8m-[3H]5-formyltetrahydrofolate (5-formylTHF) for 18 hr to label

Cleavage of Coenzyme B12 by Methylmalonyl Coenzyme A Mutase

Journal of Biological Chemistry, 1973
Abstract Methylmalonyl-CoA mutase-dependent cleavage of coenzyme B12 took place in the presence of succinyl-CoA, one of the substrates of the enzyme, and in the presence of malonyl-CoA, a competitive inhibitor (Ki 0.12 mm). Other competitive inhibitors of the reaction, including acetyl-CoA, propionyl-CoA, glutaryl-CoA, and CoA itself, did not replace ...

Development of Carbon-Fiber Electrodes Modified for Electrochemical ATP Detection [PDF]

arXiv, 2018
Adenosine triphosphate (ATP) is a highly energetic molecule used as a coenzyme in the transfer of chemical energy required for the continuation of cellular metabolism. In addition, extracellular ATP has an important role in cell-to-cell communication in immune, nervous and vascular systems.

Effect of metabolic and antioxidant supplementation on sperm parameters in oligo-astheno-teratozoospermia, with and without varicocele: a double-blind placebo-controlled study [PDF]

, 2018
Since sperm require high energy levels to perform their specialised function, it is vital that essential nutrients are available for spermatozoa when they develop, capacitate and acquire motility.
