Abstract: The invention provides an antifreeze glycolipid compounds and composition comprising a polysaccharide moiety of Formula I: wherein D-Manp represents a D-mannopyranose moiety, D-Xylp represents a D-xylopyranose moiety, and n is about 5 to about 70; and one or more lipid moieties covalently linked to the polysaccharide moiety of Formula I or electrostatically associated with the polysaccharide moiety of Formula I. The antifreeze glycolipid compounds and compositions can be used for a variety of industrial, agricultural, medical, and cosmetic applications where recrystallization-inhibition, cyroprotection, or cryopreservation is desired. The antifreeze glycolipid compounds or compositions can be used as, for example, as cryoprotectants for tissue preservation and transplantation, improving the texture of processed frozen food and frozen meats, frostbite protection, crop protection, and green alternatives for land vehicle antifreeze and aircraft de-icing.

Abstract: The present invention is directed to transgenic plants having nucleic acid sequences encoding Dendroides canadensis thermal hysteresis proteins. The THPs of Dendroides have significantly greater thermal hysteresis activity than any other known anti-freeze protein. The thermal hysteresis activity of the purified THPs can be further enhanced by combining the THPs with various "activating" compounds.
