Document Summary

4 - biological molecules, lipids and protein www. fda. gov. Complex chemicals found in living organisms not usually found in non-living systems. Polymers: molecules built from one or a few kinds of smaller molecules called monomers. Macromolecules are made by: condensation reactions or. Macromolecules are broken down by: hydrolysis reactions. Water is split during bond formation breaking. Lipids: sugars, starches, rice, grains, pasta, cereal, fruits, vegetables, flours, small amts found in every food (why?, meats, fish, poultry, dairy, beans, nuts, dark green veggies, whole grains, oil, butter, fatty meats (yum! ), fried foods broadest and most diverse group of molecule that have 2 features: Lipids: large regions with only c and h, hydrophobic and insoluble in water three major groups, oils & fats, phospholipids (membranes!, steroids (hormones) Lipids can be large molecules, but are not polymers. 4 rings of carbon fused together with various functional groups: cholesterol, testosterone, estradiol.
