1. List all the chemical bonds and interactions. Give at least one example for each. Make sure to include a biological molecule in the examples. Draw four molecules which shows polar and nonpolar covalent bond, H-bond and ionic bond.

Expert Solution

(i) Polar covalent bond: The biological molecule that has the polar covalent bond is D-glucose, where all the O-H bonds show polar covalent bonds.

In fact, all the compounds that have O-H and N-H bonds will be considered as examples of polar covalent bonds.

(ii) Nonpolar covalent bond: The biological molecule that has the nonpolar covalent bond is D-mannose, where all the C-C bonds show nonpolar covalent bonds.

In fact, all the compounds that have C-C bonds will be considered as examples of nonpolar covalent bonds.

(iii) H-bond: The biological molecules that show the intermolecular hydrogen bonds (double) are Adenine (A) and Thiamine (T). The biological molecules show the intermolecular hydrogen bonds (triple) are Guanine (A) and Cytosine (T).

(iv) Ionic bond: The biological molecule that shows the ionic bond is lactic acid, where the carboxylic acid, C(=O)O-H group show the ionic bond.
