Monomers are the building blocks of polymers. Calls link monomers
together to form polymers by a dehydration reaction. This is a reaction
that removes a molecule of water. For each monomer tat is added to a
chain, a water molecule is released.
Cells don’t only make macromolecules they must also break them down. You must digest these polymers to
make their monomers available to your cells. This is through a digestion process called hydrolysis. It means to
break with water. The bond between monomers is broken by the addition of a water molecule with the hydroxyl
group from the water attaching to one monomer and a hydrogen attaching to the adjacent monomer. Both
dehydration and hydrolysis require the help of enzymes to make and break bonds. Enzymes are specialized
macromolecules that speedup chemical reactions in cells.
3.4: Carbohydrates refers to a class of molecules ranging from the small
sugar molecules dissolved in soft drinks to large polysaccharides, such as
the state molecules we consume in pasta and potatoes. The carbohydrate
monomers are monosaccharides. Mono’s generally have molecular
formulas that are some multiple of CH2O. Mono’s. particularly glucose, are
the main fuel molecules for cellular work. Cells release energy from
glucose when they break it down, an aqueous solution of glucose may be
injected into the bloodstream of sick or injured patients, the glucose
provides immediate energy source to tissues in need of repair.
3.5: Disaccharide is formed from two monosaccharide monomers by a
dehydration reaction. One monomer
