Monosaccharides
In addition to glucose, there are two other monosaccharides, galactose and fructose, most often in the human diet.
For plants and animals, glucose is the preferred fuel source. The human brain depends on glucose, except during extreme starvation conditions.
Galactose is a monosaccharide sugar. Galactose is found in avocados, sugar beets, and dairy products. The body also synthesizes it. Galactose is utilized for energy production in cells after converting to glucose. A galactose molecule unit linked with a glucose unit forms lactose, the natural sugar in milk.
Fructose is a monosaccharide that is primarily found in fruits. Fructose is among the most common monosaccharides in nature. It is also found in some drinks, cereals, and other products sweetened with fructose-containing corn syrup.
