3 Phosphoglycerate

3-Phosphoglycerate (3-PG) is a three-carbon phosphorylated organic acid and central intermediate in cellular metabolism, linking energy production with carbon fixation. During glycolysis, phosphoglycerate kinase transfers a phosphate group from 1,3-bisphosphoglycerate to ADP, producing ATP and 3-PG; phosphoglycerate mutase then shifts the phosphate from the third to the second carbon to form 2-phosphoglycerate. In photosynthetic organisms, 3-PG is also the first stable product formed when carbon dioxide is fixed in the Calvin cycle. Its position in these pathways makes it important for studying ATP generation, carbohydrate synthesis, metabolic regulation, and photosynthetic carbon assimilation.

Source: Tamara M. Powers, Department of Chemistry, Texas A&M University One of the goals of chemistry is to use models that account for trends and provide insights into the properties of reactants that contribute to reactivity. Substances have been classified as acids and bases since the time of the ancient Greeks, but the definition of acids and bases has been modified and expanded over the years.1 The ancient Greeks would characterize substances by taste, and defined acids as those that...

ortho–para-Directing Activators: –CH3, –OH, –⁠NH2, –OCH3

All ortho–para directors, excluding halogens, are activating groups. These groups donate electrons to the ring, making the ring carbons electron-rich. Consequently, the reactivity of the aromatic ring towards electrophilic substitution increases. For instance, the nitration of anisole is about 10,000 times faster than the nitration of benzene. The electron-donating effect of the methoxy group in anisole activates the ortho and para positions on the ring and stabilizes the corresponding...

We fabricate metal/LaAlO3/SrTiO3 heterostructures using a combination of pulsed laser deposition and in situ magnetron sputtering. Through magnetotransport and in situ X-ray photoelectron spectroscopy experiments, we investigate the interplay between electrostatic and chemical phenomena of the quasi two-dimensional electron gas formed in this system.
