Question
Chapter 20, Problem 27E
(a)
Summary Introduction
To explain: The reason behind eating a large amount of eggs that are rich in phosphatidylcholine is a risk factor for cardiovascular diseases.
Concept introduction: Trimethylamine N-oxide is a small colorless
(b)
Summary Introduction
To explain: Whether ingesting phosphatidylcholine slows down the aging process or not.
Concept introduction: Trimethylamine N-oxide is a small colorless amine oxide that is generated from choline, betaine, and carnitine by gut microbial metabolism. The concentration of TMAO in the blood increases after consuming the food that contains carnitine or lecithin if the bacteria convert those substances to TMAO that are present in the gut.

For the mass spec. shown in the attached image, please determine and give the amino acid sequence of the pentapeptide. Show which end is the amino terminus and which is the carboxy terminus. How does one arrive at the solution?
Draw a tripeptide of your choosing at pH 7. Have the N-terminus on the left and the C-terminus on the right. Then:
Draw a triangle around the α-carbons.
Draw a box around the R-groups.
Circle the atoms capable of hydrogen bonding.
Highlight the atoms involved in the formation of the peptide bonds.
What type of structure have you drawn? (primary, secondary, tertiary or quaternary protein structure).

- Background Freezing isn't the only challenge in cryopreservation - thawing can be just as difficult. A microwave oven seems like a nice solution, since it deposits energy quickly and microwaves are non-ionizing radiation (they do not cause DNA mutation). However, water absorbs microwaves more effectively than ice does, meaning that the portion of an organ that has already melted will get warmer at a higher rate than the remaining ice – the opposite of what we want! - The transmission of radiation through a weakly absorbing material such as ice or water can be modeled by Beer's law, which assumes that the rate of absorption at a depth x is proportional to the local radiation intensity I(x) times an absorption coefficient, which is often written as μ or a or just µ). Noting that absorption decreases the intensity, we can write a differential equation a Solving the differential equation with the boundary condition on the surface being gives the relationship For a standard microwave oven…arrow_forward3.
