Physiological pH is between 7.37 and 7.43
Lysine is a basic amino acid, which means
it has two NH2 groups and one COOH group.
Lysine pKas are: 2.16, 9.06 and 10.05
At low pH (lower than the first pKa, in
this case: lower than 2.16) the three groups are protoned. As you increase pH,
the first group to lose its proton is the acid group, then the alpha-amino
group and then the R-amino group. You will have everything non protoned at a
high pH (higher than the highest pKa, in this case: 10.05).
Physiological pH is higher than the lowest
pKa and lower than the middle pKa, so it’s the second case: the acid is
not protoned, the R-amino is protoned and the alpha amino is protoned.
Protoned aminos are cations: NH3+.

The ratio of reactants is chlorination of <u>2,3</u> dimethyl butane the possibility of obtaining do and the polychlorinated product is not seen.
When a mixture of methane and chlorine is exposed to ultraviolet light a substitution reaction occurs and the organic product is chloromethane. Because there are various hydrogen atoms that can be extracted in the first propagation step.
Abstraction of a hydrogen atom from the middle carbon of propane results in 2-chloropropane. In the presence of sunlight, methane reacts with chlorine to form chloromethane. The chlorination of methane is a free radical substitution reaction. Chlorine cannot turn into free radicals in the dark, so no reaction takes place. Therefore, the presence of sunlight is essential for the reaction to proceed.
