Alkali-modification of carrageenans: mechanism and kinetics in the kappa/iota-, mu/nu- and lambda-series

Mostrar todas las versiones(2)

The cyclization reaction (formation of 3,6-anhydro-α-d-galactose units from α-d-galactose 6-sulfate) of carrageenans follows a pseudo first-order kinetics, being 20-60 times faster for carrageenans of the kappa-family than for those of the lambda-family. In lambda-carrageenans the clustering of the...
