Did you know that enzymes are highly specific biological catalysts, designed to act on only certain molecules? This principle of molecular recognition is why mixing sucrose and lactase results in a non-event, as the lactase enzyme has no effect on table sugar.

While most know vitamin C primarily as an antioxidant, groundbreaking research from 2004 discovered that its oxidized form, dehydroascorbic acid (DHA), directly inhibits the activity of certain kinases in cellular pathways. This dual functionality means that in addition to scavenging free radicals, vitamin C can also act as an inhibitor under specific conditions, influencing complex cellular processes like inflammation and gene regulation.
