carbohydrates 2 Flashcards
what is a polysaccharide
polymer of monosaccharides
what is a homopolysaccharide
polysaccharide made by monosaccharides
what process is glucose used in
respiration
what is the main role of energy store
energy store
what are the three main types of polysaccharide we study
amylose
amylopectin
glycogen
where are amylose and amylopectin and glycogen found
amylose and amylopectin in plants
glycogen- animals
what is an advantage of polyssacharides being compact
they can store energy wihthout using a large volume of space
what is the advantage of glucose molecules in chains
glucose can be snipped off easily and used as respiratory substrate
what polysaccharides are branched
amylopectin glycogen
is amylose branched or unbranched
unbranched
what are more compact branched chains or unbranched
branched
what bonds are present in amylose amylopectin and glycogen
amylose- -1,4
amylopectin-1,4 and 1,6
glycogen- 1,4 and 1,6
what is more soluble, polysaccharides or monosaccharides
mono are more soluble
why is it advantageous for polysaccharides to be less soluble
because if lots of glucose molecules all dissolved at the same time, the cytoplasm water potential would reduce and excess water would diffuse in.
where in the organism is glycogen stored
liver
what are the monomers of amylose and amylopectin
alpha glcuose
what is the monomer of glycogen
alpha glucose
what is the shape of amylose and amylopectin
amylose- spiral shape
amylopectin- coiled into spiral shape but with branches sticking out of it.
is glycogen more or less coiled than amylopectin
glycogen in less coiled
what is the most compact out of the three polysaccharides
glycogen- more branched so more compact
