Transcript of Biomolecules - Carbs and Lipids

  • Dutrochet
  • Modern Cell Theory All organisms are made up of cells. New cells are always produced from pre-existing cells. The cell is a structural and functional unit of all living things.
  • Modern Cell Theory The cell contains hereditary information which is passed on from cell to cell during cell division. All cells are basically the same in chemical composition and metabolic activities.
  • Atoms
  • Essential Elements of Life
  • Molecules
  • Joined together by chemical bonds
  • Sometimes, molecules bond to form very large structures called macromolecules
  • DNA is an example of a macromolecule.
  • Some macromolecules are made of the same repeating units (molecules). These are called polymers.
  • Each repeating unit in a polymer is called a monomer.
  • Macromolecules ARE VERY LARGE NOT a polymer macromolecule POLYMER!
  • Biomolecules *commonly macromolecules
  • Carbohydrates
  • Carbohydrates They are used for energy production, storage, and for structure.
  • Carbohydrates Monosaccharide Disaccharide Polysaccharide
  • Carbohydrates Monosaccharide Simplest carbs Monomers Energy for cells Formula: Multiples of CH2O
  • Carbohydrates Monosaccharide Glucose Fructose Galactose Ribose
  • Carbohydrates Disaccharide Two monosaccharides joined together by a glycosidic bond
  • Maltose Glucose + Glucose Lactose Glucose + Galactose Sucrose Glucose + Fructose
  • Carbohydrates Polysaccharide polymers of sugars that have storage and structural roles
  • Amylose / Starch -plants Storage Polysaccharides Glycogen -animals and fungi
  • Cellulose -plants Structural Polysaccharides Chitin - insects, crustaceans
  • Lipids They are used for energy storage, cell signalling, and for structure.
  • Lipids Fats, Oils, Waxes Phospholipids Steroids
  • Lipids Fats & Oils Made up of triglycerides Stored in adipose Cushions organs
  • Lipids Fats & Oils Made up of triglycerides Stored in adipose Cushions organs
  • Lipids Phospholipids Major components of cell membranes of various organisms
  • Phospholipid
  • Phospholipid Bilayer
  • Lipids Steroids Chemical basis of many animal hormones
