Aldehydes can be determined indirectly by atomic absorption. The aldehyde is oxidized with the Ag+ ion producing 2 moles of Ag for every mole of the aldehyde. Silver dissolves and is determined by atomic absorption. When examining a liquor, 50 mL were subjected to the treatment, the metallic silver was separated and dissolved, making the resulting solution 20 mL for its reading. A 10 ppm Ag solution was examined under the same conditions; The readings obtained were: 0.423 and 0.242 for the standard and the sample respectively. Assuming full adherence to Beer's Law, calculate the mg of acetaldehyde in 100 mL of liquor.
Catalysis and Enzymatic Reactions
Catalysis is the kind of chemical reaction in which the rate (speed) of a reaction is enhanced by the catalyst which is not consumed during the process of reaction and afterward it is removed when the catalyst is not used to make up the impurity in the product. The enzymatic reaction is the reaction that is catalyzed via enzymes.
Lock And Key Model
The lock-and-key model is used to describe the catalytic enzyme activity, based on the interaction between enzyme and substrate. This model considers the lock as an enzyme and the key as a substrate to explain this model. The concept of how a unique distinct key only can have the access to open a particular lock resembles how the specific substrate can only fit into the particular active site of the enzyme. This is significant in understanding the intermolecular interaction between proteins and plays a vital role in drug interaction.
