Chapter 12, Problem 14P
Interpretation Introduction

Interpretation:

The effect on the composition of fatty-acid of the membrane if the temperature of the culture of growing bacteria is changed from 370C to 250C

Concept introduction:

The plasma membrane is a two-dimensional fluid-fluid change with the temperature. Unsaturated or less tightly-packed phospholipids fatty acid causes higher fluidity of the membrane. High-temperature results in higher fluidity.

molecule. Which of the following fatty acids is an omega-3 fatty acid? bond starting with the third carbon from the methyl end (the omega end) of the Omega-3 (@-3) fatty acids are unsaturated fatty acids with a carbon-to-carbon double a-linolenic a) b) stearic oleic linoleic myristic ebil The molecule at the left is an example of which lipid? CH2 a) b) wax terpene steroid CH2 -0-P-0- d) sphingolipid glycerophospholipid bigit nisrt
Suggest a reason why the cell membranes of bacteria grown at 20°C tend to have a higher proportion of unsaturated fatty acids than the membranes of bacteria of the same species grown at 37°C. In other words, the bacteria grown at 37°C have a higher proportion of saturated fatty acids in their cell membranes.
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? (c) For another buffer with pKa=7.5PKa = 7.5 at pH 8.0pH 8.0, what is the expected ratio of [ A- ][A ] to [HA]? do
