For carbohydrates, can you explain what “orientation of glycosidic links” are and how these links influence properties of carbohydrates? Does the ratio of 1-4 or 1-6 links only affect solubility or do they play a part in other mechanisms?

Answer #1

# In carbohydrates, some links are in alpha direction (in amylose) and some are in beta orientation (in cellulose).

# Yes, the 1-6 links affect the solubility of the carbohydrate. Amylose is more soluble in water which is made up of 1-4 linkage but, amylopectin is more insoluble in water because, it contains the 1-6 linkage. This branching makes it insoluble in water. This branching makes the difference between starch and glycogen. Glycogen is stored in animal and starch is stored in plants. Starch forms a semi crystal structure due to its branching 1-6 linkage and it makes it harder to be available when there is an immediate need of glucose. That is why glycogen which has a slight diffrerence from starch is preferred by animal to store.
