Monosaccharide
Fructose
C12H22O11
When two simple sugars bond through
dehydration synthesis, a water molecule is
release:
Disaccharide – sucrose
Formed through
“dehydration synthesis” – a
glucose and a fructose
synthesize and release a
water molecule.
C6H12O6 + C6H12O6 = C12H22O11 + C6H12O6
2(C6H12O6) - H2O = C12H22O11
C24H40O20

Saturated fats have the most H possible, so they have no
double bonds.
