BIOLOGICAL MOLECULES Flashcards
methane and other compounds composed of only hydrogen and oxygen
hydrocarbons
the chain of carbon atoms in organic molecules
carbon skeleton
compounds with the same molecular formula but different structures
isomers
large biological polymers
macromolecules
Living things are made up of 4 macromolecules, being:
- Carbohydrates
- Lipids
- Proteins
- Nucleic acids
ranges from small sugar molecules to large polysaccharides
carbohydrates
molecular formulas that are multiples of CH2O
monosaccharides
a process where cells link monomers together to form polymers
dehydration synthesis
to break “lyse” with water
hydrolysis
polymer of 100-1000+ monosaccharides linked together
polysaccharide
double sugar
disaccharide
consists mainly of carbon and hydrogen atoms
lipid
In lipids, hydrogen atoms are linked by ___________.
nonpolar covalent bonds
Lipids are hydro_____.
phobic
fatty acids and fats with double bonds
unsaturated
Lipids _____ tightly together and solidify at room temperature.
do not pack
having maximum number of hydrogens
saturated
contain phosphorus and 2 fatty acids
phospholipids
consist of one fatty acid linked to alcohol
waxes
carbon skeleton forms 4 fused rings
steroids
common substance in animal cell membranes
cholesterol
