Single and bilateral sugars.. A combination of two monocrystals to form a binary sugar molecule. Lactose. Maltose. Sucrose. Glucose. Fructose. Galactose. Ribose

Single sugars:
Consists of only one molecule consisting of a series of carbon atoms (3: 6 atoms), each of which is bound to oxygen and hydrogen in a certain way.
Examples:
- Glucose (sugar).
- Fructose (fructose).
- Galactose.
- Ribose.
Bilateral sugars:
Consists of the union of two molecules of monosaccharides to form a binary sugar molecule.
Examples:
- Lactose (Glucose) (Glucose + Galactose).
- Maltose (barley sugar) (glucose + glucose).
- sucrose (sugar cane) (glucose + fructose).
