Hydrogen bonding between Guanine and Thymine and also between Cytosine and Adenine has to be indicated. Concept Introduction: Hydrogen bonding: The attractive force that holds two polar molecules (containing Hydrogen and highly electronegative atom, such as N, O, or F) is called as hydrogen boding. This is also called as intermolecular hydrogen bonding. The hydrogen bonding takes place within a molecule is called as intramolecular hydrogen bonding.

Question

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.

You ask the individual if they are taking any non-prescription drugs.  They tell you they recently started taking a coenzyme Q10 supplement based on a recommendation from a friend.  The structure of coenzyme Q10 is shown below. Looking at the structure of the molecule, which one of the 4 major classes of macromolecules (carbohydrate, lipid, proteins or nucleotides) does it most closely resemble? Be sure to include specific chemical characteristics that support this decision.

H-bonding is present in carbohydrates and proteins. Given the following structures: (a) glucose, a monomer of carbohydrates, and (b) glycine, an amino acid that is a protein building block, highlight the sites for H-bonding. H-C-OH HO-C-H Н-с-ОН H-C-OH N-C CH2OH 0-H a. Glucose b. Glycine HICI H.
