THE conversion of dehydroascorbic acid to diketogulonic acid has been studied in chemical systems 1; but, as Harris 2 has pointed out, definite evidence is not available for any enzymatically ...

It's an amazing ingredient, but the unstable nature of vitamin C makes it prone to oxidation; prolonged exposure to oxygen makes vitamin C lose its efficacy as it turns into dehydroascorbic acid. To ...

These innocent slip-ups can cause your beloved serum to become “oxidized to dehydroascorbic acid, which is less stable and less efficacious,” Dr. Hogan explains. In other words, it won’t really work.

One of the simplest antioxidants is vitamin C. Vitamin C molecules can react to form dehydroascorbic acid by losing two hydrogen atoms from the hydroxyl groups attached to the ring part of the ...

A nucleic acid is a long molecule made up of smaller molecules called nucleotides. Nucleic acids were discovered in 1868, when twenty-four-year-old Swiss physician Friedrich Miescher isolated a ...

Amino acid molecules are made of four main elements. You may remember them from science class: carbon, hydrogen, oxygen, and nitrogen. These elements form the same amino acid structure.

An acid and alkali will neutralise each other and produce a salt and water. This is called a neutralisation reaction. The name of the salt produced can be worked out from the names of the acid and ...
