While reasonable titration curves were obtained with the sugar nucleotides and UDP (Fig. 1d and Supplementary Fig. 2), the peptide unfortunately precipitated during the ITC experiment, which impeded obtaining useful data. The results of our ITC experiments demonstrated that the product of the ...
In chemistry, several related scales and calculations are used to measure the acidity or basicity of a solution, as well as to understand the strength of acids and bases. While the pH scale is the most widely recognized and frequently used, there are other important measurements such as pKa,...

A study with K-9 Greek students was conducted in order to evaluate how the declarative knowledge acquisition was affected by incorporating Arduino experiments in secondary Chemistry Education. A Digital Application (DA) that blends the use of the Arduino sensors’ experiments with digital educational ...
Phenolic compounds are ubiquitous plant secondary metabolites that possess various biological activities and are known to interact with proteins, altering their structure and properties. Therefore, interactions between these compounds and proteins has ga
