Answer

$-\text{H}$

Okay, sucess, let's draw these out. The easiest way is to remember the common backbone and then focus on the unique R-group for each.

The common backbone (in its zwitterionic form at physiological pH) is:

\begin{array}{c} H \\ | \\ H_3N^+ - \underset{R}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}

Where $\alpha\text{C}$ is the alpha-carbon, $\text{H}_3N^+$ is the protonated amino group, $\text{COO}^-$ is the deprotonated carboxyl group, and $\text{R}$ is the side chain.

Here are the structures for all 20, grouped by their R-group properties:

Nonpolar, Aliphatic R-Groups:

Glycine (Gly, G): R = $-\text{H}$
$\begin{array}{c} H \\ | \\ H_3N^+ - \underset{H}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}$
Alanine (Ala, A): R = $-CH_3$
$\begin{array}{c} H \\ | \\ H_3N^+ - \underset{CH_3}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}$
Valine (Val, V): R = $-CH(CH_3)_2$
$\begin{array}{c} H \\ | \\ H_3N^+ - \underset{CH(CH_3)_2}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}$
Leucine (Leu, L): R = $-CH_2CH(CH_3)_2$
$\begin{array}{c} H \\ | \\ H_3N^+ - \underset{CH_2CH(CH_3)_2}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}$
Isoleucine (Ile, I): R = $-CH(CH_3)CH_2CH_3$
$\begin{array}{c} H \\ | \\ H_3N^+ - \underset{CH(CH_3)CH_2CH_3}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}$
Methionine (Met, M): R = $-CH_2CH_2SCH_3$
$\begin{array}{c} H \\ | \\ H_3N^+ - \underset{CH_2CH_2SCH_3}{\overset{\alpha}{C}} - COO^- \\ | \\ H \end{array}$
Proline (Pro, P): (Unique cyclic structure where the R-group bonds back to the amino group)
