Extrusion induced low-order starch matrices: Enzymic hydrolysis and structure

Title : Extrusion Induced Low - Order Starch Matrices :

The enzymic hydrolysis of carrageenin.

Carrageenin is the water soluble polysaccharide extractable from the red algae Chondrus crispus and Gigartina stellata. The polysaccharide is essentially a polymer of alpha-D-galactopyranoside-4-sulphate. Smith et al. (1954) fractionated carrageenin with potassium chloride into two components and obtained a precipitable component which could form gels and a nongelling component which remained i...

Enzymic Mechanism of Starch Synthesis in Plants

An important development in the field of polysaccharide biochemistry has been the discovery of starch synthetase in beans, potatoes and corn seedlings by Leloir and coworkers•>. The enzyme was found to be closely bound to the starch granules and to catalyze the transfer of glucose moiety from UDP-glucose into polysaccharides containing linkage of the a-D-(H4) type. Subsequently, the granule-bou...

The Enzymic Hydrolysis of p - Glucosides

The present work arose out of an attempt to understand the course of cellulose breakdown in preparations of cellulolytic enzymes which also contained cellobiase activity. Previous investigations of the ,B-glucosidases have been of three kinds-an examination of their specificity ranges (reviewed by Veibel, 1950), the demonstration of their reversibility and the study of glucosyl transfer. Croft-...

The complete enzymic hydrolysis of proteins.

The strong acids that are required for complete hydrolysis of proteins destroy some amino acids, such as tryptophan, asparagine, and glutamine. Other amino acids are destroyed to a lesser extent or in certain cases are released incompletely from peptide linkage. It is evident that these difficulties, as well as others, could be overcome by employing proteolytic enzymes as the sole agents for hy...
