Trehalose (from Turkish tıgala – a sugar derived from insect cocoons + -ose) is a sugar consisting of two molecules of glucose. It is also known as mycose or tremalose. Some bacteria, fungi, plants and invertebrate animals synthesize it as a source of energy, and to survive freezing and lack of water.

Trehalose has high water retention capabilities, and is used in food, cosmetics and as a drug.
