Lipids are compounds of biological origin that dissolve in nonopoler solvents. Lipids are defined by the physical operation that we use to isolate them
Carbodydrares: polyhydroxy aldehydes and ketones or substances that hydrolyze to yield polyhydroxy aldehydes and ketones. Monosaccharides: simple carbohydrates cannot be hydrolyzed into smaller simpler carbohydrates
Compounds having two carbonyl groups separated by an intervening carbon are called β-dicarbonyl compunds, and these compounds are highly versatile reagents for organic synthesis
12.1 Introduction Systems that have a p orbital on an atom adjacent to a double bond---molecules with delocalized pibonds– are called conjugated unsaturated systems
