What are the 6 carbon sugars found in blood

glucose, "blood sugar", the immediate source of energy for cellular respiration

galactose, a sugar in milk (and yogurt), and

fructose, a sugar found in honey.

Although all three share the same molecular formula (C6H12O6), the arrangement of atoms differs in each case. Substances such as these three, which have identical molecular formulas but different structural formulas, are known as structural isomers.

Glucose, galactose, and fructose are "single" sugars or monosaccharides. Two monosaccharides can be linked together to form a "double" sugar or disaccharide.

Disaccharides

Three common disaccharides:

sucrose — common table sugar = glucose + fructose

lactose — major sugar in milk = glucose + galactose

maltose — product of starch digestion = glucose + glucose
