Bio Chapter 3 Flashcards
condensation
Process by which enzymes build large molecules from smaller subunits; water also forms
Enzyme
Compound (usually a protein) that speeds a reaction without being changed by it.
Functional group
A group of atoms bonded to a carbon of an organic compound; imparts a specific chemical property
hydrocarbon
Compound or region of one that consists only of carbon and hydrogen atoms
Hydrolysis
Process by which an enzyme breaks a molecule into smaller subunits by attaching a hydroxyl group to on part and hydrogen atom to the other
Metabolism
All the enzymes-mediated chemical reactions by which cells acquire and use energy as they build and break down organic molecules
Monomers
Molecules that are subunits of polymers
Organic
type of compound that consists primarily of carbon and hydrogen atoms
Polymers
Molecule that consists of multiple monomer
Carbohydrate
Molecule that consists primarily of carbon, hydrogen, and oxygen atoms in a 1:2:1 ratio
Fat
Lipid that consists of a glycerol molecule with one,two or three fatty acids tails.
Fatty acid
Organic compound that consists of a chain of carbon atoms with an acidic carboxyl group at one end. Carbon chain of saturated fats types has single bonds only; that of unsaturated types has one or more double bonds
lipid
Fatty, oily or waxy organic compound
Phospholipid
a lipid with a phosphate group in its hydrophilic head and two polar non polar fatty acids tails; main constituent of eukaryotic cell membranes
steroid
Type of lipid with four carbon rings and no fatty acid tails
