The 21 proteinogenic α-amino acids found in eukaryotes, grouped according to their side chains' pK a values and charges carried at physiological pH (7.4) 2- , alpha- , or α-amino acids [ 21 ] have the generic formula H 2 NCHRCOOH in most cases, [ b ] where R is an organic substituent known as a " side chain ".
Plate tectonics (from Latin tectonicus, from Ancient Greek τεκτονικός (tektonikós) 'pertaining to building') [1] is the scientific theory that the Earth's lithosphere comprises a number of large tectonic plates, which have been slowly moving since 3–4 billion years ago.
