What is an anabolic reaction? Catabolic reaction? Agenda for Thursday Nov 3rd Food Label activity Finish Macromolecule notes Quiz tomorrow

Macromolecules Large molecules created by joining smaller molecules Bike chain Polymer – molecules formed by repeating units of monomers 4 major categories: Carbohydrates, lipids, proteins, nucleic acids

Carbohydrates Carbon, hydrogen, and oxygen Ratio of 1 C, 2 H, and 1 O Supply most of the energy for your body Play important health-promoting roles Digestion, absorption, eliminate toxins/waste

Types of Carbohydrates Monosaccharides –1 unit simple sugars immediate energy Fruits and honey

Types of carbohydrates Disaccharides – 2 monosaccharides linked together (2 units) "simple sugars" Includes lactose (milk), sucrose (table sugar), maltose (starch) similar to monosaccharides; provide sweet taste to food and quick energy

Carbohydrates Polysaccharides – longer carbohydrate chains Complex carbohydrates Starch, Fiber and Resistant Starch Digestion takes longer Extended/sustained source of energy

Why are carbohydrates important for our body Why are carbohydrates important for our body? List some carbohydrates you may purchase in the store. Agenda for Friday Nov 4th Quiz Finish Notes Ch 7 reading guide

Lipids Carbon and hydrogen Store energy Unsaturated, or saturated Fats, oils, waxes Store energy Unsaturated, or saturated Hydrophobic – does not dissolve in water Serves as a barrier

Lipids Saturated fats are straight molecules Unsaturated fats solids at room temp. butter and fats found in meat Unsaturated fats are liquids at room temperature olive oil in oils from grains and seeds, such as flaxseed oil

Lipids and You Cell membranes contains different kinds of fats keeps membrane flexible and moveable When saturated fats are too high, cell membranes become inflexible and don't function well Body needs unsaturated fats Cell membrane Brain Anti-inflammatory - arthritis

Proteins Constitute the majority of the structural tissue in your body Bone, connective tissues, hair, muscles, skin, antibodies, hormones, enzymes Proteins are involved in just about every function in your body enzymes are proteins

Proteins Made of amino acids same structure with a variable group 20 different variable group

Proteins Need amino acids Your body will begin to break down its own muscle Stunting, poor muscle formation, thin and fragile hair, skin lesions, a poorly functioning immune system You get the majority of your protein from nuts, legumes, eggs, fish, meats and dairy products

Nucleic Acids Store and transmit genetic information Phosphate, sugar, and nitrogen base (nucleotide) Nucleotides form together to create nucleic acid DNA, RNA Nucleotide with 3 phosphates is ATP energy used by cells In everything!
