I believe it is 42.3 billion years old
Explanation:
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 pH of an acid is lower than the pH of a base. On the pH scale, 7 is neutral, 1-6 is considered acidic, and 8-14 is considered alkaline.
