The question of how long you can go without food depends on a lot of factors. Will and determination definitely play a part. Political prisoners on hunger strikes and fasting religious leaders have been known to go for weeks at a time without any food. Gandhi fasted for 21 days while in his 70s. People lost in the wild have also survived for long periods of time without eating. Medically speaking, most doctors agree that healthy humans can go up to eight weeks without food as long as they have water.
Cellulose is mostly linear chains of glucose molecules linked together by beta 1,4 glycosidic bonds whereas starch is found in both linear and branched chains. The orientation of the glycosidic linkages in cellulose makes the glucose rings to be arranged in a flip flop fashion which contributes to the rigidity.ellulose is mostly linear chains of glucose molecules linked together by beta 1,4 glycosidic bonds whereas starch is found in both linear and branched chains.

Plants synthesize a structural polysaccharide called cellulose. Although cellulose is made with glucose, the glycosidic linkages between glucose monomers are different from the bonds in glycogen and starch. This unique bond structure causes cellulose chains to form linear flat strands instead of coils.The flat cellulose strands are able to form tightly packed bundles.ther polysaccharides form strong fibers that provide protection and structural support in both plants and animals. With small differences in the bond between monomers, polymers can function as compact energy storage units in starch and glycogen or as strong, protective fibers in cellulose and chitin.
