... molecule hydrogen peroxide. The reaction between these two players -- known as a "Fenton reaction" -- can lead to the production of a highly reactive oxygen-containing chemical group called a hydroxyl radical, Franz said. These toxic chemical radicals can cause oxidative stress in brain cells that has been linked to Parkinson's and Alzheimer's as well as other age-related maladies such as...

Jedno ze zdań: "hydroxylation activity targeting the CAD was found to occur on an asparagine residues." Ja bym to tak przetłumaczył: "hydroksylacja (białka) CAD zachodzi w resztach asparaginowych" słowo "targeting" oznacza tu "dotycząca", ale ...

... orientation. Finally, the irregular spaces between the "rungs" prevent homo-DNA from taking on the uniform structure DNA uses to store genetic information. The findings suggest that fully hydroxylated six-carbon sugars probably would not have produced a stable base-pairing system capable of carrying genetic information as efficiently as DNA. "The structure now provides insight of a ...

This involves chemically changing the structure of the sugar molecules by substituting three chlorine atoms for three hydroxyl groups. mk5000 "I knew I'd found my Perfect Miss My elfin girl from down the lane And I'll never let her go again For how could I describe our ...
