Ultrasonic study of adsorption in polysaccharide metabolism

Abstract

Starch metabolism due to adsorption of enzyme amylase on the starch substrate is outlined briefly. To explore the necessary conditions required for effective adsorption in biological media, ultrasonic techniques have been applied to elucidate the structural variations and component destruction in the considered systems. The ability of the enzyme amylase to break the linkages in two different polysaccharide substrates was determined from the observed ultrasonic data, which highlights the deciding factors of metabolism. It is concluded that the phenomenon of adsorption is decided by the surface area, the number of subunits held by the substrate, and the structure existing in the adsorbent, and above all, a relatively higher quantity of enzyme than the substrate.

Ultrasonic Study of Molecular Interactions in Binary Mixtures at 303 K

“…The observed decreases values of V f in system 1 are due to close association between solute and solvent molecules than system 2. Thus it is observed that in system 2 show different results from those of other three components 13 . Thus, a progressive decrease in free volume and increase in internal pressure in water-dioxane mixtures clearly indicates the existence of ion-solvent interaction, due to which the structural arrangement is considerably affected.…”

“…Ultrasonic technique has been adequately employed to investigate the properties of any substance to understand the nature of molecular interactions in pure liquid 1 , liquid mixtures [2][3][4][5] and ionic interactions in electrolytic solutions 6,7 . Though the molecular interactions studies can be best carried out through spectroscopic methods 8,9 the other non spectroscopic techniques such as dielectric 10 magnetic 11 ultrasonic velocity and viscosity [12][13][14] measurements have been widely used in field of interactions and structural aspect evaluations studies. In the present work an attempt has been made to investigate the behaviour of binary solutions of water in 1,4-dioxane and acetone with regard to adiabatic compressibility, intermolecular free length and specific acoustic impedance from ultrasonic measurements at 303 K.…”
