Which of the following polysaccharides is found in animals? Starch Glycogen Cellulose Glucose
Polysaccharides or polycarbohydrates are the most abundant carbohydrate found in food. They are long chain polymeric carbohydrates composed of monosaccharide units bound together by glycosidic linkages. This carbohydrate can react with water (hydrolysis) using amylase enzymes as catalyst which produces constituent sugars (monosaccharides or oligosaccharides). They range in structure from linear to highly branched. Examples include storage polysaccharides such as starch glycogen and galactogenand struct…
Polysaccharides serve for the storage of energy (e.g. starch and glycogen ) and as structural components (e.g. cellulose in plants and chitin in arthropods). The 5-carbon monosaccharide ribose is an important component of coenzymes (e.g. ATP FAD and NAD ) and the backbone of the genetic molecule known as RNA .
Glucose molecules are bound in starch by the easily hydrolyzed alpha bonds. The same type of bond is found in the animal reserve polysaccharide glycogen. This is in contrast to many structural polysaccharides such as chitin cellulose and peptidoglycan which are bound by beta bonds and are much more resistant to hydrolysis. Biosynthesis
Glycogen is a molecular polymer of glucose (a polysaccharide ) used to store energy and is important for maintaining glucose homeostasis in the blood as well as for providing energy for skeletal muscle and cardiac muscle contraction. Molecules of glucose are linked into linear chains by α-1 4-glycosidic bonds.
Glycogen is a multibranched polysaccharide of glucose that serves as a form of energy storage in animals fungi and bacteria. The polysaccharide structure represents the main storage form of glucose in the body. Glycogen functions as one of two forms of ...
