Yeast mannans are phosphorylated glycopeptides found in various species of yeast. Their similarity to the mannose-phosphate signal for intracellular lysosomal uptake led mannans to be considered as a possible vehicle for increasing cellular affinity for peptides. Insulin was used as a model peptide and was conjugated to mannans by two coupling methods. The conjugated mannan-insulins were compared to insulin on the basis of cellular binding and ability to induce typical insulin biological effects.
