pre - lab questions saponification
1. What happens to the structure of a soap micelle if placed in
a non-polar solvent?
2. sodium methylsulfonate (CH3OSO2-Na +) is an inefficient
detergent. Explain why
3. what is the reason for the presence of crusts that accumulate
in the bathtubs
4. i put my results and observations in the table. the soap and
detergent used had CaCl2 but as you can see results and
observations were similiar is it becuse of the compound?...
a) Below is a sketch of a soap and a piece of nonpolar dirt. Sketch the micelle that would form when the soap is applied to the dirt. (4 pts) dirt= Scapa huompalar polar OR b) Describe the events of the Q cycle. Begin with dihydroubiquonine (UQHz) at the site. End with the formation of dihydroubiquinone (UQHz) at the on site. Account for the two electrons that reach cytochrome c. You may draw a sketch to support your essay, but...
1. Which would clean better in hard water, soap or detergent? Why? 2.What is the difference in the behavior of oil when it is mixed with water verses when it is mixed with detergent solution? Explain what is happening at the microscopic level to cause this difference.
Draw the structure of a soap surfactant molecule. Label the relevant features that enable it to be a good cleaning agent. Explain why surfactants dissolve in both water and water/oil mixtures. Use your knowledge of intermolecular forces in your explanation.
1.) Draw the structure of the amino acid Serine(ser), which has R=-CH2-OH. Label the alpha carbon. 2.) Draw the dipeptide that forms between serine and alanine. The dipeptide sequence is Ser-Ala. Label the peptide bond. 3.) How many amino acids residues are in a polypeptide containing 6 peptide bonds? How many peptide bonds are in a tripeptide 4.) Sketch a alpha-helix and a beta-sheet as best as you can. Label each.

SAPONIFICATION (HYDROLYSIS OF A FAD Fats and edible oils consitute a special class of esters called riglycerides in which alcohol part of the molecule, the trihydroxy compound glycerol, forms with three molecules of various long-chain carboxylic acids (called fatty acids). Ty reactions of simple esters can also be carried out on fats and oils,i acid-or-base-catalyzed hydrolysis. three ester linkages carboxylic acids...
