Polysacharides as energy stores
Structure
Small + compact
Don't take up space
Glucose chains can be broken down by enzymes
hydrolysis
for respiration
Some chains branched
Glycogen
Amylopectin
More compact :check:
Lots of glucose snipped by hydrolysis at once
Energy lost fast :red_cross:
Some not branched
Plants
Starch
Stored in starch grains
Amylose
α glucose chain
C 1 and 4 glycosidic bonds
Coiles held by H-bonds
OH group inside coil
:arrow_down:soluble
H-bonds can form
Amylopectin
C 1-4 glycosidic bonds
C 1 and 6 glycosidic bonds
brances emerge from spiral
Spiral shape
Animals
Stored in muscles and liver
Glycogen
More brances than amylopectin
:arrow_up: compact
Can break off more monomers because there are more ends
C 1-6 glycosidic bonds
C 1 and 4 glycosidic bonds
Smaller than amylopectin
doesn't coil
:arrow_double_down: soluble in water than monosacharides
:arrow_up: Ψ
in cell
Places that could H-bond to water are hidden away inside
Amylose :arrow_right:double helix + hydrophibic surface
Made of one kind of monosaccharide
Homosacharides
Starch
Glucose :heavy_plus_sign: Oxygen :arrow_right: Carbon Dioxide :heavy_plus_sign: Water
