Homework Answers
Answer:
1) Based on the characterstic of each type of molecule, select the way(s) in which amino sugars such as glucosamine could be separated from steroid hormones such as estradiol.
- The presence of a negatively charged group on one molecule
- the solubilities of the two molecules in water - Correct (estradiol is not soluble in water but is soluble in organic solvents like ethanol, DMSO, DMF etc. Glucosamine on the other side is soluble in water)
- the presence of a positively charged group on one molecule - Correct (Glucosamine has a positive charge at neutral pH)
2. Based on the characterstic of each type of molecule, select the way(s) in which lactate could be separated from glycerol:
- the presence of a negatively charged group on one molecule - Correct (lactate is negatively charged molecule)
- the solubilities of the two molecules in water
- the presence of a positively charged group on one molecule

In studying a particular biomolecule (a protein, nucleic acid,
carbohydrate, or lipid) in the laboratory, the biochemist first
needs to separate it from other biomolecules in the sample (that
is, it needs to be purified). Specific purification techniques are
described later in the text. However, by looking at the monomeric
subunits and functional groups of a biomolecule, you should have
some ideas about the characteristics of the molecule that would
allow you to separate it from other molecules. Look for...

In chapter 9 we learned how to make
acetylide anions and use them as nucleophiles. In order to use this
method, we will need to transform the alcohol to a different
functional group that would make the carbon a better electrophile.
