Document Summary

Functional groups a group of atoms with characteristic chemical properties that are attached to the carbon backbone of organic molecules cause changes in physical characteristics and chemical properties. Oh polar functional group due to polar covalent bond between oxygen and hydrogen found in sugars, thus goes into solution with water well. C=o (carbon with a double bond to oxygen) polar covalent bond ketone if located in the carbon chain aldehyde if located on the end of a chain. Phosphate acidic functional group by dissociation of the oh (often loses 2. Not a functional group, but important to recognize this is a non- polar bond, therefore a non-polar molecule. Compounds with a ratio of 1 carbon, 2 hydrogens, and 1 oxygen monosaccharide - 1 sugar (simple) disaccharides - 2 sugars polysaccharides - many sugars (complex) Starch: plant storage (polymaltose) maltose = 2 glucose difference between starch and cellulose is where the hydroxyl group is, determining where hydrogen bonds will occur.
