ABSTRACT:
The present invention relates to an oral delivery system, and in particular to modified amino acids or peptides for use as a delivery system of sensitive agents such as bioactive peptides. The modified amino acids or peptides can form non-covalent mixtures or microspheres with active biological agents. These mixtures or microspheres are suitable for oral administration of biologically active agents to animals. Methods for the preparation of such amino acids and peptides are also disclosed.
