- The process by which living organisms produce larger molecules from smaller ones.
- Biosynthesis
- A substance that alters the speed of a chemical reaction but does not get used up in the process
- Catalyst
- A change that alters the makeup of the elements or molecules of a substance (not reversible)
- Chemical change
- A measurement of how much solute exists within a certain volume of solvent
- Concentration
- A cheical reaction in which molecules combine by removing water
- Dehydration
- The random motion of molecules from an area of high concentration to an area of low concentration
- Diffusion
- Carbohydrates that are made up of two monosaccharides
- Disaccharides
- All atoms that contain the same number of protons
- Element
- Lacking any affinity to water
- Hydrophobic
- A strong attraction between hydrogen atoms and certain other atoms (usually oxygen or nitrogen) in specific molecules
- Hydrogen bond
- Breaking down complex molecules by the chemical addition of water
- Hydrolysis
- Two different molecules that have the same chemical formula ( have different structual formula )
- Isomers
- Anything that has mass and takes up space
- Matter
- An explanation or representation of something that cannot be seen
- Model
- Chemicals that result from atoms linking together
- Molecules
- Simple carbohydrates that contain three to ten carbon atoms
- Monosaccharides
- A molecule that contains only carbon and any of the following: hydrogen, oxygen, nitrogen, sulfur, and/or phosphorous
- Organic Molecule
- The tendency of a solvent to travel across a semipermeable membrane into areas of higher solute concentration
- Osmosis
- A bond that links amino acids together in a protein
- Peptide bond
- One of three forms -- solid, liquid, or gas -- which every substance is capable of attaining
- Phase
- A change that affects the appearance but not the chemical makeup of a substance (reversible)
- Physical change
- Carbohydrates that are made up of more than two monosaccharides
- Polysaccharides
- A lipid made from fatty acids which have no double bonds between carbon atoms
- Saturated fat
- A membrane that allows some molecules to pass through but does not allow other molecules to pass through
- Semipermeable membrane
- A lipid made from fatty acids that have at least one double bond between carbon atoms
- Unsaturated fat
