These answers are actually quite wrong. 1) Proteins are soluble and most stable when folded (laws of thermodynamics, entropy gains by folding), nobody wants to purify unfolded, catalytically inactive protein. 2) DTT does not cause unfolding. Does not. Proteins are often found in highly reducing environments, so DTT stops oxidation of the protein (especially helpful in metal containing proteins) and the formation of unwanted disulfide bonds. If your protein requires disulfide bonds then you may not want to use DTT.
A cigarette has two flavors, regular and menthol while pipe tobacco has many flavors, ranging from spicy to fruity to sweet. 3. The flavor and aroma of cigarettes are added chemically while the flavor and aroma of pipe tobacco are added while the plant is still growing by spraying them on the leaves.
Because cigarette smokers usually inhale this smoke, they are much more subject to its harmful effects than pipe and cigar smokers, who generally do not inhale. In pipe and cigar smoking, however, there is some danger to the heart because of the nicotine that is absorbed by the mouth.There is also the possibility of cancer of the lips, tongue, and mouth. Statistically, there is no question that nonsmokers are far less subject to the diseases that affect smokers.n pipe and cigar smoking, however, there is some danger to the heart because of the nicotine that is absorbed by the mouth.
