7963415988Carbon 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
7963415989Functional groupsSpecial groups of atoms that usually participate in reactions Give different compounds different properties All functional groups important to life are polar1
7963415990HydrophilicWater loving2
7963415991HydrophobicWater hating3
7963415992MacromoleculesGigantic molecules, thousands of atoms4
79634159934 Types of MacromoleculesCarbohydrates, proteins, nucleic acids, lipids5
7963415994MonomersIndividual building blocks of polymers6
7963415995PolymersChains of identical or similar molecules7
7963415996CarbohydratesMain source of energy for cellular work8
7963415997OrganicMostly carbon (C) and Hydrogen (H)9
7963415998InorganicOther elements, little or no C10
7963415999Dehydration SynthesisAdded monomers lose H or OH Release water Bond at oxygen - forms a bridge Polymer formed Building polymers/monomers together11
7963416000Hydrolysis ReactionWater added to break bonds in polymers Reverse of dehydration synthesis Breaking polymers apart12
79634160014 Characteristics of CarbohydratesMade up of rings (or ring looking structure) Made up of ration CH2O End in "ose" OH (hydroxyl group)13
7963416002Monosaccharidemonomer Simple sugar14
7963416003Disaccharide2 monosaccharides bonded Double sugar15
7963416004Polysaccharide3 or more monosaccharides bonded Complex carb16
7963416005Function of CarbsShort term energy Storage: polysaccharides17
7963416006GlycogenHow animals store excess sugar Mostly stored in liver and muscle cells When your glucose levels are low, broken down18
7963416007StarchHow plants store extra sugar Humans and other animals can break down Examples: potatoes, plantains, rice19
7963416008CelluloseStructural Make plants rigid Cell walls Can't be broken down by humans and animals Examples: corn, legumes, lettuce20
7963416009LipidsMade mostly of C and H, some O and P Mostly nonpolar Hydrophobic Common lipids: fat, oils, waxes21
7963416010Main Function of LipidsEnergy storage (long term)22
7963416011Additional functions of lipidsCushioning and insulation23
7963416012Monomers that make up lipidsGlycerol and fatty acids24
7963416013Saturated FatNo double bonds in the fatty acid Solid at room temperature SATURATED with hydrogens25
7963416014Unsaturated FatDouble bonds in the fatty acid Liquid at room temperature26
7963416015Trans FatReally bad for you - causing cancer, diabetes, obesity, other health concerns27
7963416016PhospholipidsGlycerol with only two fatty acids Major component of CELL MEMBRANES Form a double layer in water28
7963416017WaxesProtective coat for fruits and animals29
7963416018HormonesSteroids30
7963416019Proteins (Function)Structure, storage, defense, transport, and speeding up reactions Found in hair, muscles, feathers Common foods: meat, eggs, nuts31
7963416020Proteins (Structure)Monomers: amino acids Amino group, carboxyl group, hydrogen and R group Only 20 different R genes Polymers: polypeptides STRUCTURE = FUNCTION32
7963416021Protein SynthesisLink between the C and the N: peptide bond 2 amino acids joined = dipeptide bond33
7963416022Primary Protein StructureChain of amino acids34
7963416023DenaturationUnravel/altar structure of a protein DESTROY35
7963416024Secondary Protein StructureFolding/coiling pattern36
7963416025Tertiary StructureOverall 3D shape37
7963416026Quaternary StructureMultiple polypeptide chains twisted together38
7963416027Nucleic Acids FunctionStore and transmit genetic information Heredity/genetics39
7963416028Nucleic Acid monomersNucleotides40
7963416029Two types of nucleic acidsDNA - Deoxyribonucleic Acid RNA - Ribonucleic Acid41
7963416030Nucleic Acid StructureMade of C, H, O, N and P 5 carbon sugar, phosphate group, nitrogenous base42
