10 C. POLYSACCHARIDES - starches many sugars linked togetherExamples: cellulose, glycogen(Animal starch)
11 2. PROTEINS– made up of amino acids Amino groupCarboxyl(acid) group
12 *There are 20 different amino acids depending on what replaces the “R” GlycineAlanine
13 Uses: growth, maintenance and repair, hormones and enzymes DIPEPTIDE –two amino acids linked by peptide bond
14 POLYPEPTIDE – many amino acids linked by peptide bonds (protein)
15 *Some proteins are very large molecules containing hundreds of amino acids. *Often these long proteins are bent and folded and joined by hydrogen bonding.*Protein shape can be influence by conditions such as temperature.
16 One very special group of proteins are ENZYMES. Enzymes control how fast chemical reactions occur in organisms by reducing the amount of energy needed for the reaction to take place.
17 3. LIPIDS –fats, oils and waxes Monomers are Fatty AcidsUses – storage of energy and making membranes, steroids and pigments
18 *Examples:*Triglyceride - made of glycerol and 3 fatty acids*Fats and Oils
25 Examples:Deoxyribonucleic acid or DNARibonucleic acid or RNA
26 THINK POSITIVE…Do you have everything you need? (notebook, sharpened pencil, workbook and your book!!!!)Are you in your assigned seat? (before the bell rings)Warm-up: 1. Name the 4 main organic compounds found in living cells.2. What do all organic compounds have in common?
27 Make note cards or a foldable of the four types of compounds found in living cells. Included uses, drawings, examples the repeated unit that make ups the compound. Label drawings so you know what they are.
