Test for Starch Introduction and Hypothesis: In this experiment‚ we used iodine to test for starch in certain solutions. Iodine separates starch from polysaccharides‚ monosaccharides‚ and disaccharides. Starch is a curled polymer of glucose and iodine interacts with molecules‚ which changes the color of the molecules to a kind of black color. Iodine does not respond with carbohydrates that are not curled or coiled‚ thus the color stays yellowish brown. A black color result means that starch is current

The enzymatic hydrolysis of starch is carried out under milder conditions: lower temperatures (up to 1000C)‚ normal pressure‚ pH of the medium around 6 – 8. At the same time enzymatic hydrolysis is characterized by high reaction rate‚ high stability of the enzyme towards the denaturizing action of solvents‚ detergents‚ proteolytic enzymes‚ and a decrease in the viscosity of the reaction medium at higher temperatures‚ etc. Most often‚ enzymatic hydrolysis is carried out with the enzyme α-amylase from

There was a controlled and an experimental substance. The controlled substance was the one with starch in the dialysis bag‚ and the experimental substance was the one with starch and amylase in the dialysis bag. Both had the same solvent outside of the bag (Lugols and Distilled Water). The color change differed from inside and outside the bag as time went on‚ and at the end of the 45 minutes‚ the two bags had changed colors. The solute in the controlled substance had a darker color to it‚ with it

B. Statement of the problem. General Problem The problem is if cassava starch is an effective component for biodegradable plastic. Specific problems The easiest problem to solve will be the texture and bubbles. The mixture can’t be too thick when it’s being made and heated. If it’s too thick‚ air bubbles will get trapped in the mixture when it’s heated and won’t be able to get out. Try adding more water. It will take longer to dry‚ of course‚ but that will help to get rid of the bubbles

Plato’s Metaphysics in a Nutshell it is vital to know the difference Plato made between sensible "things" and "forms." Things are those aspects of reality which we see though our senses: a boy‚ a table‚ fan‚ television‚ etc. Everything that we experience in the world of impression is constantly changing (the television will start to get worn down‚ the boy will age with time)‚ imperfect and often passing away. This is the realm of appearances‚ and we all know that appearances can be deceptive.

DATABASE MANAGEMENT SYSTEM (DBMS): A database management system (DBMS) is a computer program (or more typically‚ a suite of them) designed to manage a database‚ a large set of structured data‚ and run operations on the data requested by numerous users. Typical examples of DBMS use include accounting‚ human resources and customer support systems. A database management system (or DBMS) is essentially nothing more than a computerized data-keeping system. Users of the system are given facilities to
