5.2 Poly saccharides Flashcards
macromolecules/ polymers with a few hundred to a few thousand monosaccharides joined by glycosidic linkages:
polysaccharides
polysaccharides functions:
1- store material that can be hydrolyzed as needed to provide sugar for cells 2- building material for structures that protect the cell and organism
what do plants store in the form of storage polysaccharides?
starch
starch is made of
glucoses monomers
how do plants store starch:
as granules in plastids (including chloroplasts)
most of the glucose monomers in starch are joined by ______linkages
1-4
what makes starch helical
the shape of its bonds
simplest form of starch:
amylose (unbranched)
animals store a polysaccharide called
glycogen
glycogen is where
liver and muscle cells
major component of the cell walls in plants
cellulose
alpha or beta linkage
alpha/beta linkage
cellulose
beta linkage (every other monomer is upside down)
is cellulose branched?
microfibrils
