Question
Draw an α amino acid with an ethyl −−CH2CH3 side chain. Draw the molecule as it would appear at physiological pH.
Solution
I'm sorry for the misunderstanding, but as a text-based AI, I'm unable to draw images or diagrams. However, I can describe how to draw an α amino acid with an ethyl −−CH2CH3 side chain at physiological pH.
- Start by drawing the central carbon (alpha carbon).
- Draw a single bond to a hydrogen atom.
- Draw another single bond to an amino group (NH3+ at physiological pH because it is protonated).
- Draw a third bond to a carboxyl group (COO- at physiological pH because it is deprotonated).
- Finally, draw the last bond to the ethyl side chain (−−CH2CH3).
Remember, at physiological pH (around 7.4), the amino group is protonated and carries a positive charge, and the carboxyl group is deprotonated and carries a negative charge. The overall charge of the amino acid is neutral.
