9077729145Carbon compoundscontain carbon, make up living things Can form 4 bonds Bonds can be with other elements or carbon Can be lots of shapes and sizes0
9077729146Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
9077729147HydrophilicWater loving2
9077729148HydrophobicWater hating3
9077729149MacromoleculesGigantic molecules, thousands of atoms4
90777291504 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
9077729151MonomersIndividual building blocks of polymers6
9077729152PolymersChains of identical or similar molecules7
9077729153CarbohydratesMain source of energy for cellular work8
9077729154OrganicMostly carbon (C) and Hydrogen (H)9
9077729155InorganicOther elements, little or no C10
9077729156Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
9077729157Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
90777291584 Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
9077729159Monosaccharidemonomer Simple sugar14
9077729160Disaccharide2 monosaccharides bonded Double sugar15
9077729161Polysaccharide3 or more monosaccharides bonded Complex carb16
9077729162Function of CarbsShort term energy Storage: polysaccharides17
9077729163GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
9077729164StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
9077729165CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
9077729166LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
9077729167Main Function of LipidsEnergy storage (long term)22
9077729168Additional functions of lipidsCushioning and insulation23
9077729169Monomers that make up lipidsGlycerol and fatty acids24
9077729170Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
9077729171Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
9077729172Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
9077729173PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
9077729174WaxesProtective coat for fruits and animals29
9077729175HormonesSteroids30
9077729176Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
9077729177Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
9077729178Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
9077729179Primary Protein StructureChain of amino acids34
9077729180DenaturationUnravel/altar structure of a protein DESTROY35
9077729181Secondary Protein StructureFolding/coiling pattern36
9077729182Tertiary StructureOverall 3D shape37
9077729183Quaternary StructureMultiple polypeptide chains twisted together38
9077729184Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
9077729185Nucleic Acid monomersNucleotides40
9077729186Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
9077729187Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
