9783140952macromoleculea giant molecule formed by the joining of smaller molecules, usually by a dehydration reaction.0
9783140953polymera long molecule consisting of many similar or identical monomers linked together by covalent bonds.1
9783140954monomerthe subunit that serves as the building block of a polymer.2
9783140955dehydration synthesisa chemical reaction in which two molecules become covalently bonded to each other with the removal of a water molecule.3
9783140956hydrolysisa chemical reaction that breaks bonds between two molecules by the addition of water; functions in dis-assembly of polymers to monomers.4
9783140957proteina biologically functional molecule consisting of one or more polypeptides folded and coiled into a specific three-dimensional structure.5
9783140959peptide bondthe covalent bond between the carboxyl group on one amino acid and the amino group on another, formed by a dehydration reaction.6
9783140960Primary structurethe level of protein structure referring to the specific linear sequence of amino acids.7
9783140961secondary structureregions of repetitive coiling or folding of the polypeptide backbone of a protein due to hydrogen bonding between constituents of the backbone (not the side chains). Helix or pleated sheet.8
9783140963tertiary structurethe overall shape of a protein molecule due to interactions of amino acid side chains, including hydrophobic interactions, ionic bonds, hydrogen bonds, and disulfide bridges.9
9783140964quaternary structurethe particular shape of a complex, aggregate protein, defined by the characteristic three-dimensional arrangement of its constituent subunits, each a polypeptide.10
9783140991denaturationloss of a proteins normal 3D structure; can possibly be caused by pH and temperature which affect the ionic bonds, hydrogen bonds & hydrophilic interactions11
9783140965enzymea macromolecule serving as a catalyst, a chemical agent that increases the rate of a reaction without being consumed by the reaction. most of them are proteins.12
9783140967monosaccharidethe simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also called simple sugars, they have formulas that are generally some multiple of CH2O (1:2:1).13
9783140968disaccharidea double sugar, consisting of two monosaccharides joined by a glycosidic linkage formed by a dehydration reaction.14
9783140969glycosidic linkagea covalent bond formed between two monosaccharides by a dehydration reaction.15
9783140970polysaccharidea polymer of many monosaccharides, formed by dehydration reactions.16
9783140972glycogenan extensively branched glucose storage polysaccharide found in the liver and muscle of animals; the animal equivalent of starch.17
9783140973cellulosea structural polysaccharide of plant cell walls, consisting of glucose monomers joined by B glycosidic linkages. A type of plant starch.18
9783140974lipidsany of a group of large biological molecules, including fats, phospholipids, and steroids, that mix poorly, if at all, with water (hydrophobic). No true monomers.19
9783140976saturateda fatty acid in which all carbons in the hydrocarbon tail are connected by single bonds, thus maximizing the number of hydrogen atoms that are attached to the carbon skeleton.20
9783140977unsaturateda faty acid that has one or more double bonds betwen carbons in the hydrocarbon tail. such bonding reduces the number of hydrogen atoms attached to the carbon skeleton.21
9783140979triglyceridea lipid consisting of three fatty acids linked to one glycerol molecule22
9783140980phospholipida lipid made up of glycerol joined to two fatty acids and a phosphate group. The hydrocarbon chains of the fatty acids act as nonpolar hydrophobic tails, while the rest of the molecule acts s a polar, hydrophilic head. They form bilayers that function as biological membrane.23
9783140981steroida type of lipid characterized by a carbon skeleton consisting of four fused rings with various chemical groups attached. Function as part of membranes or hormones.24
9783140982hydrophobica type of weak chemical interaction caused when molecules that do not mix with water coalesce to exclude water.25
9783140983disulfide bridgesa strong covalent bond formed when the sulfur of one cysteine monomer bonds to the sulfur of another cysteine monomer that form during a tertiary protein in side chains26
