Ch. 1: Molecules and Fundamentals of Biology
| Term | Definition |
|---|---|
| Matter | anything that takes up space and has mass |
| Element | a pure substance that has specific physical / chemical properties and cant be broken down into a simpler substance |
| Atom | the smallest unit of matter that still retains the chemical properties of the element |
| Molecule | two or more atoms joined together |
| intramolecular forces | attractive forces that act on atoms within a molecule |
| intermolecular forces | forces that exist between molecules and affect physical properties of the substance |
| monomers | single molecules that can polymerize (bond) with one another |
| polymers | substances made up of many polymers joined together in chains |
| dehydration (condensation) reaction | creates a covalent bond between monomers and releases water |
| hydrolysis | a reaction that breaks a covalent bond using water |
| carbohydrates | used as fuel and structural support & contain carbon, hydrogen, and oxygen atoms (CHO) |
| the forms of carbohydrates | monosaccharides, disaccharides and polysaccharides |
| monosaccharides | carbohydrate monomers |
| Ribose | five carbon monosaccharide |
| Glucose and fructose | six carbon monosaccharides that are isomers of each other because they share the same chemical formula but have different atom arrangements |
| disaccharrides | consists of two monosaccharides joined by a glycosidic bond / resulting from a dehydration reaction (ex. sucrose, lactose, maltose) |
| polysaccharides | multiple monosaccharides connected by glycosidic bonds to form long polymers |
| starch | form of energy storage for plants |
| glycogen | form of energy storage in animals |
