Evaluation of alpha-amylase assays with 4-nitrophenyl-alpha-oligosaccharides as substrates.

K Lorentz

Journal of clinical chemistry and clinical biochemistry. Zeitschrift fur klinische Chemie und klinische Biochemie, 21(7), 463-471 (1983-07-01)

Measurements of alpha-amylase with 4-nitrophenyl glucosides offer the following advantages over methods that rely on the formation of NADH: a short lag phase, no apparent interference by metabolites and enzymes of the sample and extremely stable substrates with low blank

Hybrid Living Capsules Autonomously Produced by Engineered Bacteria.

Bacterial cellulose (BC) has excellent material properties and can be produced sustainably through simple bacterial culture, but BC-producing bacteria lack the extensive genetic toolkits of model organisms such as Escherichia coli (E. coli). Here, a simple approach is reported for

In vitro anti-diabetic activity of flavonoids and pheophytins from Allophylus cominia Sw . on PTP1B, DPPIV, alpha-glucosidase and alpha-amylase enzymes.

D G Semaan et al.

Journal of ethnopharmacology, 203, 39-46 (2017-03-28)

Ethno-botanical information from diabetic patients in Cuba led to the identification of Allophylus cominia as a possible source of new drugs for the treatment of type 2 diabetes mellitus (T2-DM). Chemical characterization of the extracts from A. cominia was carried
