Vitamin C equivalent antioxidant capacity (VCEAC) of phenolic phytochemicals.
To express the antioxidant capacity of plant foods in a more familiar and easily understood manner (equivalent to vitamin C mg/100 g), two stable radical species, ABTS(*)(-) and DPPH(*), commonlyExpand

Subunit composition determines picrotoxin and bicuculline sensitivity of Drosophila gamma-aminobutyric acid receptors.
Few gamma-aminobutyric acid (GABA) receptor subunits have been cloned from insects. These include Resistance to dieldrin, or Rdl, and a homologue of the vertebrate GABAA receptor beta subunit. UnlikeExpand
