Notes: Unit 1--Lipids Name Date Hour

(1) What is a lipid? Type of Biomolecule Means “fat”

(2) Elements Carbon (C) Hydrogen (H) Oxygen (O)

(3) Monomer Monomer: Basic unit or Smallest unit of a polymer (larger molecule). Lipid Monomer: –Fatty Acid & Glycerol

(4) Polymer Polymer: A larger structure (molecule) made of many smaller units (monomers). Lipid Polymer: –Neutral Fat –Steroid & Hormone –Phospholipid

(5) Types of Lipids Neutral Fat: Fats & Oils Long Term Energy & Insulation Steroids: Chemical Messages Growth, Reproduction Phospholipids: Cell Membrane Structure Hydrophobic & Hydrophilic Polar Head, Nonpolar Tails

(6) Function Major: –Long Term Energy Storage –Membrane Structure Minor: –Chemical Message (Steroids & Hormones)

(7) Examples Saturated & Unsaturated Fats Oils & Grease Foods with Fat & Oil: –Nuts –Meats –Dairy

(8) Saturated, Unsaturated & Trans Fat Saturated Fat: Carbon Single Bonds  Lots of Hydrogen Around Carbons Solidify Quickly  Arterial Build Up Unsaturated Fat: Carbon Double Bonds  Less Hydrogen Cell Membranes & Energy Trans Fat: Carbon Double Bonds  Different than other Unsaturated Fats Arterial Build Up faster than normal Saturated Fats
