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
triglyceride
A fat with three fatty acid tails
wax
Water-repelent mixture of lips with long fatty acid tails bonded to long-chain alcohols or carbon rings
amino acid
Small organic compound that is subunit of proteins. consists of a carboxyl group, an amine group, and a characteristic side R group, all typically bonded to the same carbon atom.
Peptide bond
A bond between the amine group of one animo acid and the carboxyl group of another. Joins animo acids in proteins
Polypeptide
chain of amino acids linked by peptide bonds
Protein
Organic compound that consists of one or more chains of amino acids (polypeptide)
denature
To unravel the shape of a protein or other large biological molecule
prion
Infections Protein
ATP
adenosine triphosphate. Nucleotide that consists of an adenine bade, a five carbon ribose sugar and three phosphate groups
