Xylomannan

Xylomannan is an antifreeze molecule, found in the freeze-tolerant Alaskan beetle Upis ceramboides.^[1] Unlike antifreeze proteins, xylomannan is not a protein. Instead, it is a combination of a sugar (saccharide) and a fatty acid that is found in cell membranes.^[2] As such is expected to work in a different manner than AFPs. It is believed to work by incorporating itself directly into the cell membrane and preventing the freezing of water molecules within the cell.^[3]

Xylomannan is also found in the
