Textbook Question
Chapter 3, Problem 3.15PS
Shortening. A popular brand of shortening has a label on the can that identifies the product as “partially hydrogenated soybean oil, palm oil, and cottonseed oil.”
- (a) What does the process of partial hydrogenation accomplish chemically?
- (b) What did the product in the can look like before it was partially hydrogenated?
- (c) What is the physical effect of partial hydrogenation?
- (d) Why would it be misleading to say that the shortening is “made from 100% polyunsaturated oils”?

12) Back to the person who ate 300 grams of glucose, how many moles of glucose is this?
Click or tap here to enter text.
There are 2 moles.
13) If a person were to eat this much glucose all at once (that is a lot of sugar) and all this sugar enters
the blood then the person's blood sugar concentration would rise. Imagine that all this glucose is
released into the 5 liters of blood that circulate in this person. What would be the molarity of
glucose in the blood?

14) After each of these glucose molecules enter the blood they are uptaken through cell membranes
to enter cells. Within these cells glucose is broken down in a series of steps releasing carbon
dioxide along the way.
For every molecule of glucose broken down how many molecules of carbon dioxide are created?
Refer to the cellular respiration equation:

- More ratios. Through the use of nuclear magnetic resonance spectroscopy, it is possible to determine the ratio between the protonated and deprotonated forms of buffers. (a) Suppose the ratio of [ A- ]A I to [HA] is determined to be 0.1 for a buffer with pKar6.0.pKa = 6.0. What is the pH? (b) For a different buffer, 91974 suppose the ratio of [ A- ]lA J to [HA] is determined to be 0.1 and the pHpH is 7.0. In this case, what is the pKapKa of the buffer?

Name a thioester molecule that is commonly found in biochemical reactions. Explain why thioesters are “high energy” compounds. Describe the molecular structure of cellulose. How does this structure explain why cellulose forms strong fibers? Explain why digestion of cellulose takes a long time even when catalyzed by an enzyme. The enzyme phosphofructokinase transfers a phosphate from ATP to the hydroxyl group a C1 of fructose. Similar to fructose, water also has a hydroxyl group and the concentration of water is much higher than that of fructose. Explain why the phosphate is transferred to fructose and not to water.arrow_forward
- he activity. First, you need to prepare a small piece of potato (cut into a 2-inch long stick or wedge), two identical drinking glasses with equal amounts of tap water (enough to submerge the piece of potato) in them and a teaspoonful of table salt. Mark one glass as A, and the other one as B. Dissolve the salt in the water in glass A. Take note of the initial characteristics of the piece of potato, particularly its consistency (degree of firmness or hardness). Record this observation on the first column of table 22. Characteristics before Soaking Table 22: Observed Characteristics of the Piece of Potato Characteristics after Soaking in Salt Water Characteristics after Soaking in Plain Water saline solution (salt water) after an hour and take note of its consistency.
