M- macromolecule
- Name given to a very large, and in
most cases biologically important molecule.Molar mass certain to be
in the thousands of grams, at least.
- manometer
- Device used for measuring small
pressures.
- matter
- Anything that has mass and takes up
space.
- meniscus
- Curved surface of a liquid in a
container.
- metabolite
- A chemical product of metabolism.
- metal
- An element that tends to lose
electrons, forming positive ions, and is a good electrical
conductor.
- metalloid
- An element with properties
intermediate between metals and non-metals.
- meteorite
- A mass of stone or metal that has
reached the earth from outer space.
- meter
- Unit of length in the metric system,
slightly longer than 1 yard or 36 inches.
- methanogenic
- "Methane (CH4) producing";
methanogenic bacteria use hydrogen and carbon dioxide as energy
sources and produce methane and water as a result.
- methylated
- Having a methyl group
(CH3).
- micromolar
- Approximately 1x10-6
moles/liter.
- microscopic
- Seeing the situation at the particle
level: atoms, molecules, or ions.
- mitochondrion
- A membrane-bound organelle that
carries out oxidative phosphorylation and produces most of the ATP
in eucaryotic cells.
- mixture
- A grouping together of two or more
substances in which each retains its original properties.
- molality
- The molal concentration, moles of
solute per kilogram of solvent, usually given the symbol m.
- molarity
- The number of moles of solute per
liter of aqueous solution.
- mole
- The amount of substance that contains
the same number of elementary particles as are found in exactly 12
g of carbon-12.
- molecule
- The smallest unit of a compound that
has all the properties of the compound.
- monomer
- A molecule or substance which can be
polymerized, usually of low molar mass.
- monooxygenase
- An enzyme catalyzing the incorporation
of one atom from molecular oxygen into a compound and the reduction
of the other atom of oxygen to water.
- monosaccharide
- A simple sugar most commonly having 5
or 6 carbon atoms present which cannot be hydrolyzed to simpler
sugars.
