Card preview (17)
Monosaccharides
sugar monomer and are the building blocks of complex carbohydrates
Most important triose
glyceraldehyde
Most important pentose
ribose
Most important hexoses
glucose fructose galactose
Structure of glucose
It is an aldose and contains an aldehyde functional group
Galactose structure
Aldose that can be converted to glucose less stable than glucose C 3 and C4 have opposite point OH group
Sucrose
glucose and fructose
Glycosidic bonds
formed by a dehydration reaction and broken by a hydrolysis reaction
Lactose
galactose and glucose
Maltose
two glucose molecules not as sweet as sucrose
Polysaccharides
long chains of carbohydrate monomers linked together
Starches
polymers of glucose that plants use to store energy
Glycogen
synthesis when energy is high and breaks it down when energy is low in liver tends to store and use it to power muscles during exercise in skeletal muscle
Cellulose
glucose molecules linked together by beta-1,4-glycosidic bonds humans cannot digest cellulose but is an important part of fiber
Chitin
Structural support to the shells or exoskeletons of insects, crabs and mollusks
Peptidoglycan
makes up bacterial cell wall
Starch is composed of…
amylose and amylopectin
