The adrenaline test for enzymes is a colorimetric enzyme assay based on the quantification of periodate-sensitive reaction products such as 1,2-diols and 1,2-aminoalcohols by back-titration of the ...

Enzymes evolved to efficiently operate in low-temperature environments via key substitutions of amino acids in their active site, which lowers the activation energy of catalytic reactions. Life has ...

Scientists studying a COVID-19 coronavirus enzyme at temperatures ranging from frosty to human-body warm discovered subtle structural shifts that offer clues about how the enzyme works. The findings ...

This investigation tests how well the enzyme amylase performs at different pH values. Amylase is a carbohydrase enzyme made by the pancreas and by glands in and around the mouth and throat. It helps ...
