Which of the following isomers of pentane is the most volatile? 4/4 2-methylbutane 2,2-dimethylpropane n-pentane They all have the same boiling point
Galactose and glucose have the same molecular formula, and the only difference is the orientation of the hydroxyl bond at the 4' position. Why is this type of distinction of bond orientations important in biology? CH,OH CH,OH но OH H. OH - H OH H. OH HÓ OH Galactose Glucose Glucose can be metabolized into energy, but galactose cannot. The bonds have different polarity, so they form hydrogen bonds with different strengths. O Enzymes and binding proteins are specific enough to detect the different configurations and must bind one sugar or the other. O The two forms switch back and forth spontaneously, which makes the molecules more flexible and versatile.
