If we made too many errors then we could be entirely wrong about what macromolecules were in the unknown solution. The observations of the results see Fig.

Questions: A.

Testing for lipids proteins and carbohydrates lab report

Each polymeric form of each kind of macromolecule has different functions in the world and in the human body. Using another transfer pipet, add 10 drops of egg albumin solution to test tube 1. Biuret test: Test unknown for proteins. Add a drop onto the juice circle. Essay about Identification of Macromolecules- Lab Report Essay about Identification of Macromolecules- Lab Report WordsOct 30, Pages Identification of Macromolecules Introduction The most common macromolecules found in living organisms are lipids, carbohydrates, proteins and nucleic acids. Record a hypothesis for each sample treatment listed as to whether it will or will not contain protein. Add a drop onto the soda water circle. Take a picture of these See Fig. Bissonnette,

Record predicted results based on the truth that whether the sample contain reducing sugars and actual observations in the table. Place a - in the data tables for each test if the reaction in the unknown does not match the reaction of the known.

Macromolecule lab testing for the presence of macromolecules answers

Which vegetable has the most starch? Record a hypothesis for each sample treatment listed as to whether it will or will not contain the test substance, which in this case is lipid. The four controls are glucose, cornstarch, egg albumin, and vegetable oil. Record predicted results based on the truth that whether the sample contain reducing sugars and actual observations in the table. What are the controls in this lab?
