There will be millions of organic compounds that contain amine groups and carboxylic acid groups and so could be called amino acids.

There are about 20-21 amino acids found in nature and many other amino acids(about 500 or so) are artificially synthesised.

There are 21 proteinogenic amino acids (that can form proteins). The 21st is selenocysteine.
