organic chem Flashcards
four types of biomolecules
carbohydrates, lipids, proteins, and nucleic acids
functional group
a few chemical groups that are essential to the functioning and identity of biomolecules
dehydration synthesis
removing water from reactants to create a bond
carbohydrates purpose
main source of fuel and carbon
monosaccharides
simple monomers like glucose and fructose
disaccharides
2 monomers joined by dehydration synthesis, (ex: sucrose= glucose+fructose)
polysaccharide
polymer of monosaccharides, cellulose= polymer of glucose, complex and used as storage
carb elements
CHO
carb functional groups
hydroxyl, ketone/aldehyde
lipid elements
C, H, O
lipid+water
non-polar, hydrophobic
fats/oils
energy storage
phospholipids
major component of all cell membranes– glycerol backbone w/ 2 fatty acids and a phosphate group – forms bilayer sheet
steroids
hormones, cholesteral
fats are made of
glycerol and fatty acids bonded by dehydration synthesis
saturated fatty acid
have no double bonds, fully saturated with carbon
bilayer sheet
formed by phospholipids– hydrophilic head on the outsides, hydrophobic tails on the inside
unsaturated fatty acids
has at least one double bond
monomer
building block of a biomolecule
polymer
many building blocks of a biomolecule put together
how traits are made
DNA–> RNA –> proteins –> traits
