Polysaccharides Flashcards
_______________ is a polymer that contains many monosaccharide units bonded to each other by glycosidic bond
Polysaccharide
____________ is the alternate name of polysaccharide
GLYCAN
is a polysaccharide in which only one type of monosaccharide monomer is present.
Homopolysaccharide
polymers of glucose
glucans
polymers of fructose.
fructosans
It is a polysaccharide in which more than one type of monosaccharide monomer is present.
Heteropolysaccharide
It is a polysaccharide containing only alpha glucose unit. Also called as animal starch.
Glycogen
It is structural component of plant cell wall.
It is the most abundant naturally
occurring polysaccharide. The woody portion of the plants –stems, stalks
and
trunks- have high concentration of
it.
Cellulose
It is the carbohydrate reserve of plants
which is the most important dietary source for higher animals, including man.
It is found in cereals, roots, tubers, vegetables etc.
Starch
Starch consists of two polysaccharide
Amylose
Amylopectin
Is a long unbranched chain with 200-1000 D-Glucose units held by α(1-4) glycosidic linkage.
Amylose
Is a branched chain with α(1-6) glycosidic linkage branching and α(1-4) glycosidic linkage.
Amylopectin
It makes up the exoskeleton of insects and crustaceans and cell walls of some fungi.
It is made up of modified glucose monosaccharides.
Chitin
Some of the Important Heteropolysaccharides are
❑ Hyaluronic Acid
❑ Heparin
It is found in connective tissues and
skin.
