Question
Chapter 12, Problem 11P
Interpretation Introduction
Interpretation:
The difference between the PAF and the structure of phospholipids needs to be explained.
Concept introduction:
The PAF has an activating factor fatty acid exists in the carbon. It acts in allergic response and toxic shock syndrome. The structure of phospholipid contains two hydrophobic fatty acids. The phosphate can be modified with serine.

Phospholipids are the main structural lipids that comprise cellular and organellar membranes. One abundant phospholipid in bacterial cell membranes is phosphatidylethanolamine (PE), which has a generic structure shown on the right.

Distracted by your entrance into the bar, one of the humans inadvertently drank a beverage containing 80 ml methanol. Unfortunately, no medical personnel are on the station, and you do not have access to sickbay. Assume that methanol and ethanol have densities of 0.79 g/ml, and that the alcohols distribute themselves rapidly over the total volume of 73 liters of body fluids of your host. A quick check of the biochemistry textbook that you always carry with you when traversing the promenade reveals that the Km of alcohol dehydrogenase for ethanol is 1 mM and for methanol the Km is 10 mM, and reminds you that alcohol dehydrogenase converts ethanol into acetaldehyde (which can then be converted to acetyl-CoA). Alcohol dehydrogenase also converts methanol into formaldehyde, which is quite toxic to humans. Ingesting 80 ml of methanol will permanently harm the human unless you intervene.b.

- Peptides. 1. Draw the peptide Ala-Glu-Gly-Lys, as it would occur at physiological pH = 7.4. The R groups of Ala and Gly are not acidic or basic, therefore do not have a pka and the charge on these R groups is therefore independent of pH. Glu is acidic and Lys is basic, therefore the charge on these amino acids is pH dependent. The pKas are shown below. pKa N-term = 9.0 C-term = 3.5 Glu4.1 Lys = 10.5 2.
