Description
D-LEUCROSE, also known as Leucrose, is a ketodisaccharide with the chemical structure D-glucopyranosyl-α(1→5)-D-fructopyranose. It is a bond isomer of sucrose and was discovered in 1952 as a natural by-product of the fermentational product of dextran from sucrose by Leuconostoc mesenteroides bacteria. Leucrose occurs naturally in significant amounts in pollen and honey, and it is known for its non-cariogenic properties, making it a valuable sweetening agent for low-dental risk foodstuffs.
Uses
Used in Food Industry:
D-LEUCROSE is used as a non-cariogenic sweetening agent for its low risk of causing dental cavities. It is suitable for incorporation into low-dental risk foodstuffs due to its resistance to acid hydrolysis and inability to be fermented by the acid-forming microbial flora of the human oral cavity.
Used in Pharmaceutical Industry:
D-LEUCROSE is used as a substrate for the α-glucosidase of yeast and is efficiently hydrolyzed in the human small intestine to glucose and fructose. This property makes it a valuable component in the development of pharmaceutical products related to digestion and metabolism.
Used in Enzyme Production:
D-LEUCROSE is prepared from sucrose by an enzymic transglycosylation process involving α-(1-6)-glycosyl transferase or dextran sucrase. This enzyme is produced by culturing Leuconostoc mesenteroides bacteria, making D-LEUCROSE an essential component in the production of these enzymes for various industrial applications.
Used in Research and Development:
The unique properties of D-LEUCROSE, such as its resistance to acid hydrolysis and its non-cariogenic nature, make it an interesting subject for research and development in various fields, including food science, pharmaceuticals, and biotechnology.
Check Digit Verification of cas no
The CAS Registry Mumber 7158-70-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,1,5 and 8 respectively; the second part has 2 digits, 7 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 7158-70:
(6*7)+(5*1)+(4*5)+(3*8)+(2*7)+(1*0)=105
105 % 10 = 5
So 7158-70-5 is a valid CAS Registry Number.
