Maltotriose Specification

The Maltotriose, with the CAS registry number 1109-28-0, is also known as D-Glucose, O-α-D-glucopyranosyl-(1-4)-O-α-D-glucopyranosyl-(1-4)- (9CI). It belongs to the product categories of Basic Sugars (Mono & Oligosaccharides); Biochemistry; Sugars; Trisaccharides. Its EINECS number is 214-174-2. This chemical's molecular formula is C18H32O16 and molecular weight is 504.44. What's more, its systematic name is alpha-D-glucopyranosyl-(1->4)-alpha-D-glucopyranosyl-(1->4)-D-glucose. It is stable at common pressure and temperature, and it should be sealed and stored in a cool and dry place. What's more, it should be protected from strong oxides. When using it, you should avoid contacting with skin and eyes. Maltotriose is a trisaccharide (three-part sugar) consisting of three glucose molecules linked with α-1,4 glycosidic bonds. It is most commonly produced by the digestive enzyme alpha amylase (a common enzyme in human saliva) on amylose in starch.
