Organic Molecules (Macromolecules ) Building Blocks of Life
Organic Molecules Molecules that have carbon atoms C 6 Carbon
Carbon is a component of all organic molecules Can share 4 outermost electrons 6 P 6 N e-
Carbon Compounds Can have many carbon atoms Can from single, double, and triple bonds with other carbon atoms C CC CC C
4 Principle Types of Organic Compounds Carbohydrates Fats Proteins Nucleic Acids
Carbohydrates Made of C, H, and O Building block: simple sugars (monosaccharides-single sugar)
Disaccarhides Two monosaccharides linked together by a condensation reaction
Polysaccharides Largest carbohydrate molecule Composed of many monosaccharide units Common examples: Starch, Glycogen, Cellulose
Lipids (Fats & Oils) :
Lipids Made of C, H, and O (but less O than a carb) Building block: 1 glycerol backbone + 3 fatty acids
Lipids Saturated: has single covalent bonds between each carbon Unsaturated: has double covalent bonds between carbons
Proteins Made of C, H, O, S, N Building block: amino acids
Nucleic Acids Made of C, H, O, N, P Building block: nucleotides
5 types of nitrogen bases
Nucleic Acids DNA-2 chains RNA-1 chain Stores genetic info—unique order of nucleotides for each living organism Nucleotide order determines amino acid order
