# Apparently referring to concentrations of tritiated amino acids and

#
# TBq mmol(-1) and GBq mmol(-1)

# where (-1) is of course an exponent. What are these TBq and GBq?
# I'm guessing T is tera and G is giga. I've no clue as to the Bq.
According to CRC Handbook of chemistry and physics:
Bq = becquerel, that is a unit for radioactivity (number of decays /
second), 1 MBq = 27 microcurie
# Later, referring to a permeability surface area product (the paper is
# about transfer across the blood-brain barrier) they use the units:
#
# ml/hg/min
#
# I've often seen the PS product as ml/g/min, but what's 'hg'?
probably hectogram = 100 grams.
