Definition: A type of enzyme that helps change one form of a molecule into another form that has the same atoms but a different arrangement.

Example: Isomerases play a crucial role in metabolic processes by converting substrates into their isomers.

Definition: Relating to or having the same molecular formula but different structural arrangements of atoms.

Example: The two compounds are isomeric, meaning they have the same chemical formula but different structures.

Definition: The condition or phenomenon where two or more compounds have the same chemical formula but different structures or properties.

Example: Isomerism is important in chemistry because different isomers can have very different effects in biological systems.

Definition: The process of changing a chemical compound into a different form that has the same atoms but a different arrangement.

Example: Isomerization is an important process in organic chemistry that helps create different compounds from the same elements.

Definition: Changed from one form to another that has the same chemical formula but a different arrangement of atoms.

Example: The isomerized compound has different properties than its original form.

Definition: Relating to a system or condition where measurements or dimensions are equal, often used in geometry and physiology.

Example: The isometric exercises helped improve her strength without changing the length of her muscles.

Definition: A line that connects points that have the same measurement or value in a specific context, often used in geometry or design.

Example: The architect used an isometric to illustrate the dimensions of the building.

Definition: A line on a map or graph that connects points with the same value of a certain measurement, like temperature or pressure.

Example: The meteorologist used an isopleth to show areas of equal rainfall on the weather map.

Definition: A type of medication that mimics the effects of adrenaline and is used to treat slow heart rates.

Example: The doctor prescribed isoprenaline to help increase the patient's heart rate.

Definition: A clear, colorless liquid that is used mainly to produce synthetic rubber and is known for being flammable and volatile.

Example: Isoprene is a key ingredient in the production of synthetic rubber used in tires.

Definition: Relating to a type of organic compound that has a specific structure based on isoprene units, often found in natural substances like rubber and certain vitamins.

Example: The isoprenoid compounds in the plant contribute to its aroma and flavor.

Definition: A type of chemical compound that is made from one or more units of isoprene, which is a building block for many natural substances.

Example: Many essential oils contain isoprenoids that contribute to their fragrance and therapeutic properties.
