Organic molecules concept map

Living organisms contain a variety of organic molecules, including macromolecules such as proteins, carbohydrates, and nucleic acids. Enzymes, which are proteins, act as catalysts to speed up biochemical reactions, with their activity centered around the active site.

Organic molecules concept map

Dehydration synthesis: The process of joining two molecules together following the removal of water forming a larger molecule

Polymers: A long chain of subunits forming a molecular structure

Nucleic acids: Nucleotide chains that transfer and express genetic information, they are polymers of nucleotides

Proteins: Amino acid chains with a variety of functions such as transporting and are polymers of amino acids
Peptide bond: Links amino acids together to form peptides and polypeptides.
Amino acid: Has a central atom bonded to a hydrogen atom and three other groups attached.
RNA: A nucleic acids present in all living cells that acts as a messenger carrying DNA instructions.
DNA: Self replicating material present in nearly all living organisms

Carbohydrates: Sugars that store energy such as starch or glycogen and are polymers of glucose. Carbs always have a 1:2:1 ration of carbon (1), hydrogen (2) and oxygen (1).

Disaccharide: Made up of two monosaccharides (e.g. maltose)
Monosaccharide: Contains between 3-7 carbon atoms (e.g. glucose)

Monomers: Single subunits (molecules) that can be attached to make polymers

Lipids: Consists of glycerol paired with fatty acids used for energy storage in cell membranes

A
Unsaturated fats: Have some double bonds between carbons leaving room for additional H atoms. They are liquid at room temp and have a plant source.
Saturated fats: No double covalent bonds between carbon atoms, therefore contain all possible H atoms. They are solid at room temp and come from an animal source.

Subunits: A single protein molecule that assembles with another protein molecule to form a protein complez

Hydrolysis: When water is added to a large molecule in order to break it down

Organic molecules: A molecule found in a living organism

Macromolecules: Relatively large complex organic molecules found in living organisms

Isomer: One of two or more compounds made of the same formula but with a different arrangement of atoms in the molecule

Enzymes: A substance produced by a living organism that serves as a catalyst to bring about a specific biochemical reaction

Inhibitors: A substance that slows down or stops a reaction within the body
Competitive inhibitors: Inhibitors that compete with the substrate trying to enter the active site in order to slow or shut down a reaction
Non-competitive inhibitors: An inhibitor that attaches to a site and forcibly changes the shape of an enzyme in order to shut or slow it down
Active site: A region on an enzyme that binds to a protein / substrate during a reaction
Induced fit: When the active site changes shape in order to fit the reacting substrate
Substrate: Molecules in the body that carry out certain functions or tasks
Catalyst: A substance that increases the rate of a chemical reactions
