Term
What are polymers
Definition

large molecules made up of monomers

-they're everywhere

Term
what are monomers
Definition
the things being repeated to make a polymer
Term
What are the two names for how the bonds prom between monomers to make polymers
Definition
  1. condensation reaction 
  2. dehydration synthesis
Term
what is condensation/ dehydration synthesis
Definition
where a water is taken away to form a bond
Term
What is hydrolysis
Definition
adding water back into the system and breaking the covalent bond
Term
what are the4 types of macromolecules
Definition
  • carbohydrates
  • lipids
  • proteins
  • nucleic acids
Term
what are carbohydrates made out of
Definition
monomer- monosaccharide
Term
Carbohydrates are hydrophilic/phobic and nonpolar/polar?
Definition
hydrophilic and polar
Term
what is Glucose
Definition
a ring with multiple OH groups and one Carbonyl group, 6 carbons
Term
what are disaccharides
Definition

2 sugar rings

ex: lactose

Term
what does -ose mean
Definition
sugar
Term
what is glycosidic linkage
Definition
bond between two sugars
Term
what is sucrose?
Definition

glucose+fructose

- sugar in candy and cooking

Term
what is fructose?
Definition
the sugar found in plants
Term
what are polysaccharides and what roles do they play?
Definition
  • a chain of many simple sugars
  • energy storage
  • structural support
Term
What is starch
Definition
  • a carbohydrate
  • energy storage in plants
  • long, linear molecules of glucose
  • no branching
Term
what does amylose mean
Definition
no branching
Term
what is amylase?
Definition
breaks down amylose
Term
what is glycogen
Definition
  • stores energy in animals
  • many branching
Term
what is cellulose?
Definition

structural support found in the cell wall of plants

  • extensive hydrogen bonding
  • give rigidity that gives plant cells its characteristic shape
Term
What are Lipids known as
Definition
fats
Term
are lipids hydrophilic/ phobic
Definition
hydrophobic
Term
what is Glycerol
Definition
chain of three carbons with a hydroxyl Group on each
Term
what are the monomers of Lipids
Definition
  • Glycerol and fatty acids
Term
What are fatty acids
Definition
  • nonpolar
  • long carbon chain
Term
what are saturated fatty acids
Definition

a chain with only single bonds and is full saturated with hydrogens

-linear overall

Term
what are unsaturated fatty acids
Definition
  • a chain with at least one double bond because the presence of a double bind means not as many hydrogens
  • its a cis configuration
Term
what are trans fatty acid
Definition
  • also have a double bond but this chain is a trans configuration
Term
Why are fats important ?
Definition
  • long term energy storage
  • cushioning of the bones and organs
    • Lipids
    • hormones and steroids
Term
what is cholesterol
Definition
Critical part of cell membrane and the cell would break and fracture without cholesterol to keep it flexible
Term
What are proteins
Definition

structurally the most divers

50% of dry mass of cells

  • accelerate chemical reactions
  • give structure
  • store energy
  • transmit messages
Term
what are Proteins monomers
Definition

Amino Acids

- have a Carbon with an amino acid on one side and a Carboxylic group on the other, an "R" group in middle

Term
what are the "R" groups in proteins
Definition
dictate shape and function
Term
there are over 20 naturally occurring amino acids, what are they?
Definition
  1. hydrophobic- negative "R" groups
  2. Hydrophilic- positive/polar "R" group
  3. Acid- negative charged "R" group
  4. Base- Positive charged "R" group
Term
what is a peptide bond
Definition
forms binds for proteins
Term
What are the 4 levels of protein structure?
Definition
  1. Primary- linear chain of amino acids; not seen in nature very often,
  2. Secondary- protein has started folding around itself based on interactions between groups
  3. Tertiary- helices and sheets stan interacting together
  4. Quaternary- more than 1 chain interacting together
    1. can for hydrocarbon, ionic, hydrophilic, disulfuric bond/bridge 
Term
What is Sickle Cell Anima
Definition
where an amino acid is messed up and it can't code
Term
What are Nucleic Acids
Definition
information storer/ movers and energy movers
Term
What are the monomers for Nucleic Acid
Definition

nucleotide

5 carbon sugar, a phosphate group, and a nitrogen base

Term
What is a phosphodiester bond
Definition
a bond the forms between nucleotides
Term
Nitrogen bases
Definition
ring structure
Term
what is antiparallel
Definition
where the 3'and 5' meet up
Term
DNA
Definition
  1. deoxyribonucleic acid
  2. deoxyribose
  3. made with thymine 
  4. double stranded
Term
RNA
Definition
  • ribose
  • uracil
  • single stranded- can from secondary structures
Term
adding more phosphate to something allows it to store more energy: True or false
Definition
yes
