Document Summary

Lecture 3: carbon, carbohydrates and lipids study notes. Large variation in the arrangement of the carbon skeleton. Diversity in length, # of branches, double bonds, ring structure. Part of the alcohol group (specific names usually end in -ol) Ex. ethanol: the alcohol present in alcoholic beverages. Polar as a result of electrons spending more time near the electronegative oxygen atom. Can form hydrogen bonds with water molecules, helping dissolve organic compounds such as sugar. Part of ketones group if the carbonyl group is within a carbon skeleton. Part of the aldehydes group if the carbonyl group is at the end of the carbon skeleton. A ketone and an aldehyde may be structural isomers with different properties, as is the case for acetone and propanal. These two groups are also found in sugars, giving rise to two major groups of sugars: Part of the carboxylic acids or organic acids. Ex. acetic acid, which gives vinegar its sour taste.
