Enzymatic Hydrolysis of Adenosine 3',5'-Phosphoric Acid

Enzymatic hydrolysis of adenosine 3',5'-phosphoric acid.

During recent years the work of Sutherland and his associates (l-3) on the liver phosphorylase system has done much to clarify the mechanism of epinephrine-induced hyperglycemia. These workers have shown that epinephrine stimulates glycogenolysis by increasing the level of active phosphorylase in dog liver slices (3, 4) and in cell-free homogenates (5). The effect of epinephrine was shown to be...

Response surface optimization of corn stover pretreatment using dilute phosphoric acid for enzymatic hydrolysis and ethanol production.

Dilute H(3)PO(4) (0.0-2.0%, v/v) was used to pretreat corn stover (10%, w/w) for conversion to ethanol. Pretreatment conditions were optimized for temperature, acid loading, and time using central composite design. Optimal pretreatment conditions were chosen to promote sugar yields following enzymatic digestion while minimizing formation of furans, which are potent inhibitors of fermentation. T...

Extraction of cellulose nano-crystals from old corrugated container fiber using phosphoric acid and enzymatic hydrolysis followed by sonication.

Due to its amazing physicochemical properties and high environmental compatibility, cellulose nano-crystals (CNC) hold great promise for serving as a strategic platform for sustainable development. Now, there has been growing interest in the development of processes using waste or residual biomass as CNC source for addressing economic and environmental concerns. In the present work, a combined ...

The kinetics of the enzymatic hydrolysis of hyaluronic acid.

Synthesis and enzymatic hydrolysis of glutamic acid polypeptides.

Synthetic lysine polypeptides of high molecular weight (1) have been shown to reduce virus infectivity (2, 3), inhibit bacterial growth and respiration (4), agglutinate virus particles, bacterial cells, and erythrocytes (4-6), and to prolong blood clotting time (7). It has been suggested that most of these phenomena are associated with the formation of many ionic bonds between the positively ch...
