oxidase

In this study, the researchers used a zeolite called iron-modified aluminum silicate, paired with an enzyme called alcohol oxidase.

Ado is originally an oxidase enzyme that adds an oxygen atom to the substrate -- isoeugenol.

"We found lactate oxidase nanocapsules helped prevent the immune system from being weakened and overcome the immune suppression caused by the tumor," Cao said.

Just like apples that turn brown after slicing, eggplants also contain the enzyme polyphenol oxidase.

When printed on fabric and worn, pH indicators, for example, could convey information about skin health or dehydration; lactate oxidase could measure a wearer's fatigue levels.
