Alpha-Amylase
Efficient Carbohydrate Breakdown: Catalyzes the conversion of starch and glycogen into maltose and glucose, providing readily available energy.
Robust Stability: A small, resilient enzyme that maintains activity under harsh environmental conditions.
Wide Biological Distribution: Naturally present in plants, animals, and microorganisms, enabling diverse sources and applications.
Supports Metabolism: Facilitates the transformation of complex carbohydrates into simple sugars, aiding energy utilization in humans and animals.
Alpha-amylase is an enzyme that hydrolyzes α-linkages in polysaccharides like starch and glycogen. It is a compact and highly stable molecule, capable of maintaining activity under challenging conditions. By breaking down starch and glycogen into maltose and glucose, it provides a readily available energy source for humans and animals. This enzyme is naturally widespread, occurring in a variety of plants, animals, and microorganisms.

α-Amylase has been widely used in plant research, such as metabolic studies in Arabidopsis. In biomedical applications, human pancreatic α-amylase has been applied to investigate potential interference in enzymatic assays for calcium measurement in serum and urine. Additionally, α-amylase from Sigma has served to create standard calibration curves for automated amylase detection systems in forensic sample analysis.
