Small, round, or elliptical particles make up starch. It is insoluble in water and alcohol and has no color, smell, or taste other than a little distinctive flavor. Because of its adaptability and affordability, starch has been used often in the manufacturing of pharmaceuticals (Muazu et al. 2012 ).
Starch is a complex branched-chain homopolymer of glucose that has a wide range of M w and size-distribution for amylose and amylopectin. Starches are linked with α-1,4-glycosidic bonds, and branched points are made of α-1,6-glycosidic bonds. The M w of polymers differs within plant species, as Table 1 shows the structure of amylose from …
Carbohydrates are the most common type of organic compound. A carbohydrate is an organic compound such as sugar or starch, and is used to store energy.
