Reducing Proteins or Peptides with Dithiothreitol (DTT) 1. Make a 1M diothreitol DTT stock solution in water, best to make fresh. (Try not to inhale the DTT.) 2. Add DTT to the protein or peptide solution (which is in a buffer) to a final concentration of 1mM to 10 mM DTT. Incubate for 10 min. to 30 min. The reduction may work slightly better if incubating at higher temperature, such as at 37 degrees C or at 56 degrees C. However, room temperature or ice should work too.
All chocolate is made from the cacao (cocoa) bean, and cacao beans in their natural, unprocessed, unadulterated state are rich in nutrients and beneficial to health. Cacao powder is simply the cacao bean, that through a cold-pressing process, has had the fat (cacao butter) removed.
While some might think cacao and cocoa are one in the same, they're not, exactly. Cacao is the tree, while cocoa is the product made from it (not to be confused with coca, an evergreen shrub from which cocaine is concocted).Edible parts of cacao pods and the beans inside them can be processed to make cocoa powder, cocoa butter, or chocolate after being dried and fermented.Because cocoa beans were prized for their medicinal and aphrodisiacal properties, they were traded just like currency among ancient South American civilizations.hile some might think cacao and cocoa are one in the same, they're not, exactly.
