Notes: Abstract A decaglutamic acid primer is extended very slowly byα-thioglutamic acid. The addition of bicarbonate to thereaction mixture greatly accelerates the reaction. We believethe N-carboxyanhydride of glutamic acid is an intermediate inthe accelerated reaction. When K3Fe(CN)6 andbicarbonate are both present in the reaction mixture,oligoglutamic acids up to at least the 15-mer are formedrapidly. The acylating agent is the oxidation product ofthioglutamic acid, a diacyldisulfide.
