Cards

Term
Hydrolysis
Definition
The process of breaking down a polymer
Term
Condensation Reaction
Definition
The process of monomers combining to become a polymer
Term
Monomer
Definition
Small, simple molecules used to build carbon compounds
Term
Polymer
Definition
A molecule that consists of repeated, linked units
Term
Organic Compounds
Definition
Compounds made primarily of carbon atoms
Term
Single Bond
Definition
A bond formed when two atoms share one pair of electrons
Term

Funtional Groups

 

Definition
Clusters of atoms in organic compounds
Term
ATP
Definition

An organic compound composed of adenosine (an adenine ring and a ribose sugar) and three phosphate groups

 

Term
Carbohydrates
Definition
Organic compounds composed of carbon, hydrogen and oxygen
Term
Monosaccharide
Definition
A monomer of a carbohydrate
Term
Disaccharide
Definition
Two monosaccharides combined after a condensation reaction to form a double sugar
Term
Polysaccharide
Definition
A complex molecule composed of three or more monosaccharides
Term
Protein
Definition
Organic compounds composed mainly of carbon, hydrogen, oxygen and nitrogen
Term
Amino Acid
Definition
Monomer of protein
Term
Dipeptide
Definition
After two amino acids go through a peptide bond, they form into this.
Term
Polypeptide
Definition
If three or more amino acids form a chain after bonding, this is what they become
Term
Enzymes
Definition
Special proteins that affect the rate of chemical reactions; enzymes are catalysts used in digestion and synthesis
Term
Substrate
Definition
Substrate is a molecule upon which an enzyme acts. Enzymes catalyze chemical reactions involving the substrate(s). In the case of a single substrate, the substrate bonds with the enzyme active site, and an enzyme-substrate complex is formed.
Term
Active site
Definition
The folds of an enzyme
Term
Lipids
Definition
Large, nonpolar organic molecules
Term
Fatty Acids
Definition
Unbranched carbon chains that make up most lipids
Term
Triglycerides
Definition
A lipid composed of three molecules of a fatty acid joined to one molecule of the alcohol glycerol
Term
Phospholipids
Definition
A lipid that has two, rather than three fatty acids attached to a molecule of glycerol
Term
Wax
Definition
A type of structural lipid consisting of a long fatty-acid chain joined to a long alcohol chain
Term
Steroid
Definition
Lipid composed of four fused carbon rings with various functional groups attached to them
Term
Nucleic Acids
Definition
Very large and complex organic molecules that store and transfer inportant information in the cell
Term
DNA
Definition
Contains information that determines the characteristics of an organism and directs its cell activities
Term
RNA
Definition
Stores and transfers information from DNA that is essential for the manufacturing of proteins
Term
Nucleotide
Definition
A monomer of nucleic acids that is made up of three components: a phosphate group, a five carbon sugar and a ring-shaped nitrogenous base
