GGT (GAMMA-GLUTAMYL TRANSPEPTIDASE)
GGT is believed to be involved in the transport of amino acids and peptides into cells as well as glutathione metabolism. GGT is mainly found in liver cells and as such is extremely sensitive to alcohol use. Elevated levels may be found in liver disease, alcoholism, bile-duct obstruction, cholangitis, drug abuse, and in some cases excessive magnesium ingestion. Decreased levels can be found in hypothyroidism, hypothalamic malfunction and low levels of magnesium.

But there’s a controversy in this field of biogeography, noted Liliana Katinas, a professor at the National University of La Plata in Argentina who was not involved in the study, in an email to Gizmodo. Do new species come from animals populating new territory (called dispersal), or did populations get separated during Earth’s breakup (called vicariance)? New methods in biogeography put many in favor of dispersal as the prime factor. “The authors of this paper are trying to return to the previous ideas and re-emphasize the role of the rupture of continent in some organisms’ distribution,” said Katinas.
