Lab organic chemistry: molecules of life date: name: general biology 1 constitute the only type of organic molecule that, even if sometimes big as a molecule, do not make it is called a macromolecule (macro=large) the presence of glycosidic bonds allows lugol’s reagent to react with the starch this reagent contains iodine, which. Requires a deeper appreciation for the basic principles of how organic molecules and water - the most fundamental molecule required by life interact to create ordered complexity. Organic compounds called proteins are important for growth and repair lipids are organic compounds that can supply as much as four times the amount of energy as carbohydrates or proteins you can perform qualitative tests to identify the presence of organic compounds in food using indicators , chemical substances that react in a certain way. The molecule would be polar, and the bond has no good name in organic chemistry, except to call it a polar covalent bond the bonds in many organic compounds can be considered independent of one another, so that the total bond energy, the heat of formation, is approximately the sum of the individual bond energies.

Organic compounds are the major components of cells and tissues they provide energy for life processes, participate in and regulate metabolic reactions, and transmit information organic macromolecules in living organisms can be classified as either carbohydrates, proteins, lipids , or nucleic acids, among others. Another class of carbohydrates called starches, a polysaccharide, can be detected using the iodine's test having a high molecular weight, iodine attaches to the helical structure of starches yielding a blue-black precipitate.
