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...
متن کاملThe 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...
متن کاملThe Conditions for Complete Hydrolysis of Proteins
Henriques and Gjaldbaek,l in an article devoted chiefly to a study of the above subject with the form01 titration, find that, when proteins are hydrolyzed with acid, both amino nitrogen and ammonia increase up to a certain point, at which the amino nitrogen attains its maximum. When hydrolysis is continued beyond this point, a transformation of amino nitrogen into ammonia follows, indicating a ...
متن کاملThe 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-...
متن کاملThe pH-dependence of enzymic ester hydrolysis.
The esterases of animal tissues have generally been characterized by their substrate specificity and by their behaviour towards various inhibitors. The irreversible inhibition by organic phosphates, which is due to phosphorylation of the active group (Burgen, 1949; Wilson & Bergmann, 1950a; Aldridge, 1953d), is a common property of most esterases, an interesting exception being the Aesterase of...
