The amino acid shown is alanine drawn with wedges. The configuration of its stereocentre is

At the alpha carbon of alanine the priorities are $\mathrm{NH}{}_2$ (N) first, then $\mathrm{COOH}$ (C attached to O,O,O) over $\mathrm{CH}{}_3$ (C attached to H,H,H), and $\mathrm{H}$ last. Viewed with $\mathrm{H}$ away from the viewer, $\mathrm{NH}{}_2\to \mathrm{COOH}\to \mathrm{CH}{}_3$ runs anticlockwise in the drawing, so the configuration is $(S)$. This is L-alanine, the natural enantiomer.
