Biosynthesis of Starch Introduction: In this lab we learned the concept and procedure of synthesizing starch. We also learned the effects of pH and temperature on the reaction rates of amylase.. In the process of the synthesis lab we learned phosphorylation using a potato‚ which was what we synthesized. The phosphorylation took place after the addition of primer. There are two different types of starches used are amylose and amylopectin. To test for the presence of starch‚ the Starch Test is used

“Is Starch Permeable in Cells? Abstract This report presents the weights of 3 samples of water with various amounts of solute after the use of osmosis. Three different tests were performed‚ each with a beaker of water containing varying amounts of starch from 30% concentration (12.5 grams of water) to 15% concentration (9.5 grams of water)‚ and then 0% (10.5 grams of water). To start this experiment‚ we put water into a make-shift dialysis tube‚ a type of semi-permeable membrane tubing made

Accordingly‚ varieties of modified starches are used in food industry. Table 1 lists some of the modified starches that can be prepared from different sources to meet the marketing-related requirements. Today‚ modified food starch is a food additive and limits of its modification‚ use and labeling are clearly defined

Resistant starch (RS) is starch and starch degradation products that escape from digestion in the small intestine of healthy individuals.[1] Resistant starch is considered the third type of dietary fiber‚ as it can deliver some of the benefits of insoluble fiber and some of the benefits of soluble fiber. Some carbohydrates‚ such as sugars and most starch‚ are rapidly digested and absorbed as glucose into the body through the small intestine and subsequently used for short-term energy needs or stored

a negative result. To explain‚ both DI water‚ and sucrose alone do not contain a trace of protein. In addition‚ deionized water is commonly used in experiments as a negative control. In both experiments‚ if the DI water is tested for a protein or starch‚ then it will come back as a negative. If milk solution‚ and 50% egg white solution are tested for proteins using the biuret solution‚ then there will be positive results because both of these are composed of protein macromolecules.
