I actually remember the basic amino acids based on their side chains. However, you can determine their basicity through their ability of being protonated and form a positive charge (amines are basic). Also, for acids, they form negative charge when they deprotonate (COOH -> COO-). You also need to note that there are neutral but polar amino acids, such as asparagine and glutamine (the amide group isn't basic). They are called neutral because they aren't acidic nor basic, but are polar because they can form hydrogen bonds.
Glycine is the only amino acid that isn't chiral, so it isn't optically active. 18 amino acids demonstrate S-configuration, except cysteine (it has R-configuration). Overall, 19 amino acids are chiral and are optically active, and 1 amino acid (glycine) is nonchiral and optically inactive.
