CARBOHYDRATES
POLYSACCHARIDES :
many monosaccharides joined in condensation reactions with glycosidic bonds
Starch : ar -
glucose polysaccharide for energy storage in plants ( in seeds and storage organs )
Insoluble : does not affect water potential of a cell 1 water does not enter due to osmosis)
large : does not diffuse out of the cell Compact .
:
large amounts stored in a small place
Hydrogen bonds can hold helix shape in
place
Unbranched or branched I branched has
many ends can be acted on by enzymes )
Mix of AMYLOSE Im branched .
long compact
, . Per storage or AMYLOPECTIN I branched , hydrolysed
quickly to release glucose ,
not used Br storage
Glycogen polysaccharide : found in animals and bacteria but never plants
Highly branched and compact Pound mainly in the muscles and liver
shorter chains of a -
glucose Insoluble and large
animal cells glycogen
Mam storage molecule in animals -
get energy from glucose ,
excess in
Cellulose polysaccharide
: of B-glucose with straight unbranched chains which run parallel
Hydrogen bonds form cross linkages between adjacent chains which add collective strength
Each alternate monomer rotated 1800 .
Good structural material
lellulose grouped to form micro fibrils , arranged in parallel groups of fibres
component of all walls :
provides ridgity and prevents the cell from bursting as water enters by
exerting inward pressure making all turgid ,
maintains stems and leafs ,
max surface area
for photosynthesis
