5464564815Carbohydrate-main source of energy -structural support in plants and some animals, instant energy, exoskeleton -composed of C, H, O in 1:2:1 ratio -monomer= monosaccharides -double sugars= disaccharides -polymer= polysaccharides RINGS0
5464780864Lipids-fats oils and waxes -do not dissolve in water -mostly C H and a few O -functions= energy storage, waterproofing, structure, hormones, cushions organs, insulation -LINEAR monomer= glycerol polymer=triglyceride = 3 fatty acids and a glycerol1
5464827797Nucleic Acid-store and transmit genetic material -composed of p o n c h -two types- dna and rna2
5470821201Protein-composed of c n h o (S) -monomer= amino acid -polymer= polypeptide/ protein -function= enzymes, structure, communication/ transportation, defense, movement3
5464564812Adhesion-water molecule attracted to another substance - responsible for capillary action that allows trees to take up ground water from their roots4
5464564813Amino Acid-monomer of proteins5
5464564814Amino GroupA functional group that consists of a nitrogen atom bonded to two hydrogen atoms6
5464564816Cohesion-water molecule attracted to water molecule -responsible for surface tension that gives many organisms a habitat to live7
5464631757Capillary ActionA process powered by adhesion that causes water molecules to move upward through a narrow tube such as the stem of a plant.8
5464631758Dehydration SynthesisA type of chemical reaction in which the molecules of substances bond together to form more complex substances- water is released -2 molecules covalently bond by removing a water molecule -one molecule loses a -oh and the other loses a -h9
5471251111Disaccharide-2 rings, double sugar molecule -lactose, sucrose10
5464696918DNA-Deoxyribonucleic acid -store and transmit genetic materials -double stranded -has thymine -one less oxygen than ribose11
5464696919Fatty Acid-type of lipid -do not dissolve in water - mostly C H and a few O -saturated vs unsaturated12
5464736061Glycerol-monomer of lipid -3 carbon -triglyceride= 3 fatty acids and 1 glycerol13
5464736062Hydrogen Bond-strongest of the intermolecular forces -when h atom bonds to a highly electronegative atom (like o and n) exists in the vicinity oof another highly electronegative atom with a lone pair of electrons - big role in living organism s -h bonds to O N or F14
5464753110Hydrolysis-the breaking down of large molecules into smaller molecules -water is added to form the molecules and disrupt the bond linking the monomers together15
5464780863IndicatorsLugols- turns starch black Benedicts- turns monosaccharide (carbs) orange Biuret- turns protein lavender16
5464780865Macromolecules- biomolecules are examples of macromolecules - giant molecules in living things that are made from 1000's of smaller molecules -all macromolecules are made by the process of polymerization= making large molecules from smaller molecules17
5464812863MonomerA simple compound whose molecules can join together to form polymers18
5464812864Monosaccharide-monomer of carbohydrates -glucose, fructose, galactose -different shape gives each of these sugars different tastes19
5464827796Nucleotide-monomer of nuclei acids - made of nitrogenous base, 5 carbon sugars, phosphate group20
5470238412Peptide Bond-amino acids are held together by peptide bonds n-c-c21
5470281414Phosphate Group-type of functional group -OPO3 -molecule in the backbone of DNA and RNA that links adjoining bases22
5470449744Phospholipids-building blocks of a cellular membrane -they have a polar head that is hydrophilic (water loving) and a non polar tail that is hydrophobic (water fearing)23
5470641157PolymerA long molecule consisting of many similar or identical monomers linked together.24
5470670328Polymerization-a chemical process that makes large molecule from smaller molecules -occurs through dehydration synthesis depolymerization= biomolecules broken down, occurs through hydrolisis25
5470814188Polysacchride-polymer of carbs -examples= starch, cellulose, glycogen, chitin26
5470834567RNA-ribonucleic acid -has sugar ribose -single stranded -one more oxygen than dna -has uracil instead of thymine27
5470836221Saturated Fat-fatty acids with only single covalent bonds between carbon atoms are saturated -straight long chain -animal fats, butter, lard - a lot of h -saturated fats are bad because they stack easily which clogs up blood vessels28
5470836222Surface Tension-cause of cohesion= water attracted to water -more tension = more difficult to break surface -provides habitat for many animals29
5470837652Steroids-type of lipid -carbon skeleton has four interconnected rings, different functional groups attached -derived from cholesterol - includes many hormones= sex hormones, gluocorticoids, mineralocorticoids30
5470837653Transfat-trans fats occur when h atoms are on opposite sides of the double bond, creating symmetry -as a result, fatty acid is linear, so it behaves like saturated fat31
5470838989Unsaturated Fat-fatty acids that contain one or more double bond between two carbon atoms are unsaturated -good for you, dont stack32
5489247475Hydroxyl Group-OH33
5489249584Carbonyl Group34
5489255340Carboxyl Group35
