15. Some molecules that are covalently bonded do not have a difference in charge across the mol-
ecule. These molecules are referred to as nonpolar. What arrangement of electrons would result
in a nonpolar molecule?
16. Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances
interact with water?

Mixtures of amino acids can be analyzed by first separating the mixture into its components through ion-exchange chromatography. Amino acids placed on a cation-exchange resin containing sulfonate (-SO₁) groups flow down the column at different rates because of two factors that influence their movement: (1) ionic attraction between the sulfonate residues on the column and positively charged functional groups on the amino acids, and (2) hydrophobic interactions between amino acid side chains and the strongly hydrophobic backbone of the polystyrene resin. For each pair of amino acids listed, determine which will be eluted first from the cation-exchange column by a pH 7.0 buffer.

- 1. Draw 8 phospholipid molecules arranged to show how the phospholipids will orient themselves on the surface of the water. This should be a single layer or monolayer. Label the hydrophilic and hydrophobic parts of a phospholipid. 2. Now draw 8 phospholipids, arranged so that they are submerged in the water while still maintaining the correct hydrophobic and hydrophilic interactions. This structure is called a micelle. 3) Draw a structure that is both submerged in water and contains water on the inside. Draw phospholipids oriented to form a cell membrane, with the tails in and the hydrophilic heads out.arrow_forwardGive Explanation Detailed Solutionarrow_forwardHow do cats drink? Scientists using high-speed video have shown that cats use an interesting technique to drink substances water and Four times a second, the cal touches the tip of its tongue the water and draws a column of water up into its mouthbefore pull the water back down.

D water water The different components of an individual phospholipid are held by covalent bonds. The attraction between the individual lipid tails inside the cell membrane is maintained by van der Waals forces. The attraction between the phosphate groups and the water molecules inside and out. side of the cell is maintained by hydrogen bonds. The bonds between the individual phospholipids that make up the cell membrane are connected by covalent bonds.arrow_forwardHow do phospholipids interact with water molecules? Phospholipids do not interact with water because water is polar and lipids are nonpolar. The polar heads interact with water; the nonpolar tails do not. The polar heads avoid water; the nonpolar tails attract water (because water is polar and opposites attract). Phospholipids dissolve in water.arrow_forward
