Chapter 8, Problem 29RQ
Summary Introduction
To review:
The reactions involving the conversion of galactose into a glycolytic intermediate with the help of Haworth formulas.
Introduction:
Galactose is a monosaccharide sugar, which means that it cannot be broken down further to produce more sugar units. Galactose is an epimer of glucose, which means that the two molecules differ in their configuration at the stereogenic center only. A stereogenic center is a pointthat holds all the ligands present in a compound. During the metabolization of galactose, certain enzymes are involved that help in the formation of the intermediates involved in the process of glycolysis.
The structural formula of all compounds involved in the

- 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.
