Sequence Variability Analysis of Human Class I and Class II MHC
... Given a multiple sequence alignment, V per site ranges from 0 (totally conserved site) to 4.3 (all 20 amino acids are present, and at the same frequency). In an absolute sense, any site with V . 0 is polymorphic. However, several V ranges can be designated to categorize polymorphic sites of HLA mole ...

Since we have defined acids and bases by the ions they release in solution, the first requirement is that they contain H or OH, respectively. However, there are plenty of compounds that contain oxygen and hydrogen atoms ...
