Question
Chapter 5, Problem 30CQ
(a)
Summary Introduction
To calculate: The molecular mass of the hen egg-white lysozyme (HEWL) for peaks 5 and 6 of ESI-MS spectrum.
Concept introduction: The proteins involves creating positively charged ions of the protein and separating them according to their mass to charge ratio (m/z) is called Electrospray ionization mass spectrometry (ESI-MS). It is the ionization technique to produce ions using an electrospray from macromolecules.
(b)

Weiss published their study of membrane lipid phosphatidylcholine (lecithin) synthesis in rat liver. Their hypothesis was that phosphocholine joined with some cellular component to yield lecithin. In an earlier experiment, incubating 32 P-labeled phosphocholine at physiological temperature (37 °C) with broken cells from rat liver yielded labeled lecithin. This became their assay for the enzymes involved in lecithin synthesis.

- Researchers isolated an unknown substance, X, from rabbit muscle. They determined its structure from the following observations and experiments. (a) Qualitative analysis showed that X was composed entirely of C, H, and O. A weighed sample of X was completely oxidized and the H2O and CO2 produced were measured. This quantitative analysis revealed that X contained 40.00% C, 6.71% H, and 53.29% O by weight. (b) The molecular mass of X, as determined by mass spectrometry, was 90.00 atomic mass units (u). (c) Infrared spectroscopy showed that X contained one double bond. (d) X dissolved readily in water, and the solution demonstrated optical activity when tested in a polarimeter.
