4871241854Amino AcidsBasic building blocks of protein molecules0
4871241855ProteinsLarge molecules composed of one or more long chains of amino acids and are an essential part of all living organisms, especially as structural components of body tissues such as muscle, hair, collagen, etc., and as enzymes and antibodies.1
4871242641EnzymesType of protein found in all living things that changes the rate of chemical reactions2
4871242642Peptide Bondstype of bond formed between amino acids to create a protein3
4871243628CarbohydratesSimple sugars or complex molecules containing multiple sugars4
4871243629LipidsOrganic compounds used by cells as long-term energy stores or building blocks as well as protection and insulation. Composed of carbon and hydrogen with a small amount of oxygen5
4871245441Deoxyribonucleic AcidDNA, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.6
4871245442Ribonucleic AcidRNA, a nucleic acid present in all living cells. Its principal role is to act as a messenger carrying instructions from DNA for controlling the synthesis of proteins, although in some viruses RNA rather than DNA carries the genetic information.7
4871246880PolymersLarge molecule formed when many smaller molecules bond together8
4871246881MonomersA simple molecule that repeatedly combines to form a polymer9
4871248117BiomoleculesA molecule (chemical compound) that is important for life. Most contain C, H, and O, and are polymers of smaller subunits10
4871272010Nucleic AcidsComplex biomolecules, such as RNA and DNA, that store cellular information in cells in the form of a code.11
6043921680NucleotidesBasic units of DNA and RNA molecules, composed of a sugar, a phosphate, and one of 5 nitrogenous bases12
7396379461ReactantsA starting material in a chemical reaction13
7396379462ProductsThe elements or compounds produced by a chemical reaction.14
7396383274SubstrateA specific reactant acted upon by an enzyme15
7396383275DenatureTo change the shape of a protein and render it ineffective.16
7396387095Active SiteThe region of an enzyme where substrate molecules bind and undergo a chemical reaction17
7396396494BuffersSubstances that minimize changes in pH18
7396470228pHA measure of how acidic or basic a solution is19
7396536699OrganicConsisting of or deriving from living matter; relating to or denoting compounds that are carbon based20
7396536700InorganicNot consisting of or deriving from living matter; relating to or denoting compounds that are not carbon based21
7396536701ElementA substance that cannot be broken down into simpler substances22
7396540294Activation EnergyThe minimum amount of energy required to start a chemical reaction23
