Conformational behaviour of substrate 1. The three major conformations in solution of the 1 that differ from the value of the phi torsion of the Siaα2-3Gal linkage: the g, -g and t. The glycosidic torsion angles definition was ϕ = C1-C2-O2-C3′, ψ = C2-O2-C3′-H3′. Discovery Studio 2016 Software (www.3dsbiovia.com) was used to draw the conformations.
