Organic compounds composed of carbon, hydrogen, and oxygen in a ration of about 1:2:1, but they vary | Carbohydrate |
A monomer of a carbohydrate; also known as a simple sugar, that contains carbon, hydrogen and oxygen 1:2:1 | Monosaccharide |
The term for a double sugar, or two monosaccharides combined in a condensation reaction | Disaccharide |
A complex molecule composed of three or more monosaccharides | Polysaccharide |
Organic compounds composed of mainly carbon, hydrogen, oxygen, and nitrogen | Protein |
When linked, these monomers create proteins | Amino Acid |
When two amino acids for a covalent bond in a condensation reaction, they are called a- | Peptide Bond |
When amino acids form very long chains they are called- | Polypeptide |
RNA or protein molecules that act as biological catalysts that are essential for the functioning of any cell | Enzyme |
The reactant that is being catalyzed in an enzyme reaction | Substrate |
The folds, or parts of the enzyme/substrate where they meet in the reaction | Active Site |
Large, nonpolar organic molecules that do not dissolve in water | Lipid |
Unbranched carbon chains that make up most lipids | Fatty Acid |
A type of lipid, among phospholipids, steroids, waxes and pigments | Triglyceride |
have two instead of three fatty acids attached to a molecule of glycerol | Phospholipid |
A type of structural lipid consisting of a long fatty acid chain joined to a long alcohol chain | Wax |
Molecules composed of four fused carbon rings with various functional groups attached to them -not composed of fatty acids | Steroid |
Very large and complex organic molecules that store and transfer important information in the cell | Nucleic Acid |
Contains information that determines the characteristics of an organism and directs its cell activities | Deoxyribonucleic Acid (DNA) |
Stores and transfers information from DNA that is essential for the manufacturing of proteins; some act as enzymes | Ribonucleic acid (RNA) |
The term for the monomers that make up DNA and RNA, and has three main components: a phosphate group, a five-carbon sugar, and a ring-shaped nitrogenous base | Nucleotide |
