Living matter consists mainly of carbon, oxygen, hydrogen, and nitrogen , with smaller amounts of sulfur and phosphorus . These elements are linked by strong covalent bonds. Carbon with its four covalent bonds is the basic building block in molecular architecture. The great diversity of organic molecules with their special properties emerge from the unique arrangement of the carbon skeleton and the functional groups attached to the skeleton. Important functional groups include: hydroxyl, carbonyl, carboxyl, amino, sulfhydryl, and phosphate groups. The chemical elements of life: a review

For Lipids… Know the elements of typical lipids Describe the building-block molecules, structure, and biological importance of fats, phospholipids, waxes and steroids Identify an ester linkage and describe how it is formed Distinguish between saturated and unsaturated fats Explain the advantage of storing energy in lipid form, compared to storage as a carbohydrate Chapter 5 continued – The structure and function of macromolecules (aka biomolecules) As before… Learning objectives: List the four major classes of macromolecules Be able to describe each type of macromolecule in terms of: Elemental composition, molecular structure/subunits, and function(s) Distinguish between monomers and polymers Be able to recognize and illustrate condensation rx and hydrolysis rx

Lipids… are diverse basically composed of C, H, O, & one type also has P are the one class of large biological molecules that DO NOT consist of polymers share the common trait of being hydrophobic So, if they’re hydrophobic, are they polar or nonpolar molecules?
