ScienceBiologyChemistry.Jessica Leonard. This lab was done to test for macromolecules consisting of carbohydrates, lipids, proteins, and nucleic acids by using specific reagents to test for each. The result would bring out a specific color change in the macromolecule. A color change would verify the sample positive for that macromolecule.

An educated guess was made that glucose and sucrose held simple sugars and starch did not. The results concluded this. For starch, iodine was used as a reagent. The hypothesis was that color would change blue-black on the starch sample and not on the sugar samples. Also, tested was an onion and potato. The hypothesis was that the potato contained starch and the onion did not. The results of this were also conclusive. For proteins, Ninhydrin and biuret was used as the reagent. Ninhydrin tested for both amino acids and protein.

Biuret tests for protein only. For this experiment the only hypothesis was that the starch sample would more than likely not change color. The results included color changes with Ninhydrin solution on the Amino acid sample and the Albumin sample. Also the color changed for the Albumin sample when tested with Biuret reagent. For lipids, Sudan III was the reagent used. The hypothesis was that color would change with corn oil. The results concluded this and that egg white samples and honey did not contain lipids.Search this site.

Other chemicals such as water, salts and minerals are also present and vital to living cells. Characteristic tests to identify each of the four major classes of biological molecules are described below. Carbohydrates such as starch are detected by mixing a sample with 2—4 drops of iodine or Lugol's solution.

The solution will turn from a yellow-brown color to a dark purple if starch is present.
