Starch is widely used in various fields because of its diverse functions. The premise of studying its functions is to obtain high-purity starch samples quickly and economically. CD BioGlyco has many advanced platforms to provide technical support for customers' starch research. We have confidence to be your essential research assistant in the field of glycobiology.
Starch is the main carbohydrate in many types of plant cells. It is found in staple foods such as potato, wheat, corn, rice, and cassava, with content ranging from 14% to 75%. It is a polymerized carbohydrate composed of numerous glucose units connected to each other by α-1,4-glycosidic bonds. Starch exists in the form of discrete semi-crystalline starch granules (SGs) and belongs to the group of polysaccharides. Because of the difference in the coiling of intramolecular hydrogen bonds into helical structures, it can be divided into amylose and amylopectin. The former has an unbranched helical structure while the latter has 24 to 30 glucose residues and the branch is an α-1,6-glycosidic bond.
Starch plays an important role in plant growth, development, and response to abiotic stress. It is also widely used as food for humans and animals and industrial raw materials. Starch dissolves in warm water to produce dextrin, which can be used as a thickening agent, and as an adhesive in the papermaking process after hardening. Starch is also used to produce various bioplastics, such as polylactic acid. To better study its structure and function, it is essential to purify high-quality starch. study its structure and function, it is essential to purify high-quality starch for research.
