is glycogen more branched than starch

Glycogen is a polysaccharide composed of glucose units linked by alpha 1-4 glycosidic bonds, with occasional alpha 1-6 glycosidic bonds which provide branching points. Glycogen is a highly branched, complex carbohydrate made from many thousands of glucose molecules bonded together. However, there exists branched polysaccharides which are branched by virtue of certain molecules being linked to a molecule via alpha 1,4 and another via alpha 1,6 glycosidic bonds. Starch, Glycogen & Cellulose In class and our lab we had to set up a table to state the major differences or similarities between the three most important Polysaccharides on the planet, and I found that to be an easier way as it is a lot of information to take in. Starch is a carbohydrate consisting of two components amylose (15 20%) and amylopectin (80 85%). This helical structure is stabilised by hydrogen bonds between -OH groups on subsequent glucose units.

These molecules of glucose are bound to each other through glycosidic bonds to form polysaccharides. One of the best definitions of Glycogen is the fact that it is called animal starch and is found in body parts like the stomach, muscle cells, and liver cells. Starch has two molecules in its chemical structure. 2. First, the starch has to be broken down in a chemical reaction called hydrolysis, where a water molecule is added between two bonded glucose molecules, breaking them apart. Carbohydrates are a type of energy-rich nutrient; this group includes sugars, starches, and fibers. Glycogen is produced from glucose where excess Both of these starches are shown in Figure 5. Starch is mainly found in cereals, vegetables, roots, tubers etc. Both form glycosidic bonds between branched (Figure 5). As a result of the bond angles in the beta acetal linkage, cellulose is mostly a linear chain. An iodine test can be used for the detection of starch in a given sample.
