  1. Dehydration Synthesis (Condensation Reaction) Hydrolysis Is how larger molecules are Is how larger molecules are • Can use more than once • Removing water • Polymers • Monomers • Adding water • Built up • Broken down • Starch glucose+ glucose+ glucose • Glucose + fructose  sucrose. by by So bonds can be made between So bonds in Are broken down into To build up for example For example

  2. Carbohydrates Foods Used for Different levels of complexity Means 1 sugar Means 2 sugars Means many sugar examples examples examples v v v v v v v Found in insects for Found in plants for Found in plants for Found in animals for v v v v • Glucose • Lactose • Pasta • Storage • Structure • Energy • Galactose • Fruit • Glycogen • Sugar • Starch • Sucrose • Cellulose • Disaccharide • Cell wall • Polysaccharide • chitin • Short term energy storage • Fructose • Exoskeleton • Monosaccharide • Milk

  3. Are used for foods Lipids 1. 2. 3. 1. 2. 3. 4. All lipids are (Which means they do not mix with water) 3 groups or classes of lipids are v v Made of have 4 fused rings and makes up Goes towards the inside away from water Used for v and v v v Which can be v Liquid at room temp and contains Examples Component of Solid at room temp v v v v If there is too much it can lead to v Goes towards the outside toward water v v Examples v v

  4. Lipid word bank: • Oils • Triglyceride • Hydrophobic • Steroids • Cholesterol • Insulation • Cell membranes • Protection • Testosterone • Unsaturated • Butter • Waxes • Fatty acids • Estrogen • Saturated • Long term energy storage • Hormones • Component of cell membrane • fats • Avacado • Phospholipids Bilayer • Glycerol • Cardiovascular Disease ( Heart Disease) • Hydrophobic Tails • Cell membrane • Hydrophilic Head • Chemical Signals • Steak

  5. Foods Proteins 1. 2. 3. 4. Used for 1. 2. 3. Made up of • Word bank for proteins: • Peptide bonds • 20 amino acids • Proteins • Meat • Hormones (chemical signals) • Structure (hair and nails) • Dairy • Eggs • Beans • Enzymes Which have the following chemical structure(draw) Build up by forming these bonds To make polypeptides which can then form

  6. Test for Organic Molecules Use indicators To Test for Lipids Carbohydrates Protein Mixed with On paper it will turn If protein is present it will turn Mixed with Mixed with + If starch is present it will turn Heat For 5 minutes • Word Bank • Biuret Solution • Heat for 5 min • Orange • Proteins • Make it look waxy • Purple • brown Is simple sugars are present it will turn • Blue • Benedict’s Solution • Starch • Simple monosaccharaides • Iodine • Blue/black • Lipids • Sudan Red IV • Get spotted
