Abstract In order to study the condition of starch hydrolysis with thermostable -amylase the influence of the substrate concentration temperature and pH were investigated The kinetics parameters – Km and Vma x were determined using Michaelis – Menten equation and the other its forms – Lineweaver - Burk Hanes - Woolf and Eadie - Hofstee
Why is the breakdown of starch?
- Starch is the main form of dietary, digestible carbohydrates. The process of digestion involves the breakdown of a complex molecule into the simplest form the body can use. Once the starch molecule is broken down, the small intestine transfers it into the bloodstream, where it is shuttled to the cells that need it. Also, how does the body ...
Why is starch insoluble in alcohol?
- Starch becomes soluble in water when heated. ... Why is glucose insoluble in alcohol? Alcohol molecules have only one polar area and also have a larger nonpolar area. This makes alcohol not a good dissolver of polar substances. Also, the water and alcohol interact, ...
Is starch hydrolyzed into maltose by any enzyme?
- Maltose. Maltose is produced by the enzymatic hydrolysis of starch (a homopolysaccharide) catalyzed by the enzyme amylase. Maltose is further hydrolyzed by the enzyme maltase to produce two molecules of d-glucose. The monosaccharide unit on the left is the hemiacetal of the ?-d-glucopyranosyl unit.
What are the products of starch hydrolyzed?
- most common final products of starch hydrolysis can be maltodextrins, glucose, fructose or maltose. The hydrolysis of starch is generally preceded by gelatinization. Gelatinization is a term that includes all events occurring as starch is heated in water: absorption of water by the starch granules, increase of the apparent viscosity of the ...
