PURPOSE: To obtain an enzyme capable of catalyzing the oxidative reaction for producing an aldehyde, a carboxylic acid and a ketone from an alcohol and an aldehyde, especially producing 2-keto-L-gluconic acid (2-KGA) from L-sorbose through L-sorbosone.朝倉 明...
Vanities are an important piece of the bathroom, but they can be expensive to replace. If you have an outdated or beat-up vanity, it might be a good idea to replace it with a new one. If your vanity is in good condition and just a bit outdated, consider painting it for a fresh lo...

With a funded trust, a trustor places assets into the trust during their lifetime. An unfunded trust consists only of the trust agreement with no funding. Unfunded trusts can become funded upon the trustor’s death or remain unfunded. Since an unfunded trust exposes assets to many of the per...
Is a certain reaction possible? How can I determine the composition of an unknown substance? Boiling it down to the basics At the most fundmental level, chemistry can be organized along the lines shown here. Dynamics refers to the details of that rearrangements of atoms that occur during ch...
“A lot of people who are moving to the area are coming from big cities, and may not be used to being friendly with their neighbors. Here, our communities are pretty tight-knit – which is a positive thing, in my opinion. Being open to getting to know the folks you’r...

The second transformation, known as the Fischer-Tropsch synthesis, generally entails contacting the synthesis gas with a catalyst under temperature and pressure conditions that allow the synthesis gas to react and form hydrocarbons. More specifically, the Fischer-Tropsch reaction is the catalytic hydrogena...
Notably, when a single equivalent of 8 was used for the D-A reaction, a bromonaphthoquinone was readily prepared, presumably with the intermediacy of a mono cycloadduct61. The crude 9 was treated with K2CO3 and MeI to give compound 11 (45% overall yield from 5). 11 underwent Clemmensen...
