◉ polymer.
Answer: a long molecule consisting of many similar or identical
building blocks linked by covalent bonds
◉ monomers.
Answer: repeating units that serve as the building blocks of a
polymer
◉ enzymes.
Answer: specialized macromolecules that speed up chemical
reactions in cells
◉ dehydration reaction.
Answer: A chemical reaction in which two molecules covalently
bond to each other with the removal of a water molecule.
◉ hydrolysis.
, Answer: A chemical reaction that breaks bonds between two
molecules by the addition of water; functions in disassembly of
polymers to monomers.
◉ carbohydrates.
Answer: Organic compounds composed of carbon, hydrogen, and
oxygen in a ratio of one carbon atom to two hydrogen atoms to one
oxygen atom. They exist as monosaccharides, disaccharides, and
polysaccharides.
◉ monosaccharides.
Answer: The simplest carbohydrate, active alone or serving as a
monomer for disaccharides and polysaccharides. Also known as
simple sugars, the molecular formulas of are generally some
multiple of CH2O.
◉ aldose.
Answer: a monosaccharide sugar that contains the aldehyde group
or is hemiacetal
◉ ketose.
Answer: any monosaccharide sugar that contains a ketone group or
its hemiacetal
