  • What a protein made up of?

    • made up of amino acids

    • amino acid-hydrogen atom, carboxyl group, r group, and a amino acid

  • What forms when amino acids are linked to peptide bonds?

    polypeptides (this is aka condensation reactions)

  • what are the four levels of the protein structure?

    primary: order of polypeptides

    secondary: folding and stabilizing of the hydrogen bonds

    tertiary: creates the 3D shape

    quaternary: the different arrangements of the polypeptides.

  • what is a nucleic acid made up of?

    polymers of nucleotide monomers

  • what are nucleotides made of?

    ( hint three components)

    5-carbon sugars (deoxyribose and ribose)

    phosphate group

    nitrogen base (purines and pyrimidines)

  • what is the structure of a nucleic acid?

    order of sugars

    nitrogenous base structure ( lots of nitrogen)

  • what is the difference between DNA and RNA??

    DNA- contains deoxyribose, structure is double helix and A-T + G-C, held together by hydrogen bonds.

    RNA- contains ribose, structure is different shapes and A-U instead of A-T

  • what are carbohydrates also known as?

    sugars!

  • what are carbohydrates made up of?

    monomers called monosaccharides

    ( have same formula, but different structure)

  • what is the molecular formula for carbohydrates?

    (ch2o)n

  • how do monosaccharides polymeize?

    through condensation reactions

  • what is the functions of polysacchrides?

    energy storage

  • what are examples of lipids?

    ex: waxes, oils, fats, and steroids

  • what is the monomer is lipids?

    no monomer!

  • true or false lipids can dissolve in water?

    flase! lipids are insoluble

  • are saturated fats solid or liquid at room temp?

    what about unsaturated fats?

    solid.

    liquid.

  • in saturated fats ...

    the carbon is bonded to the max # of hydrogens

  • in unsaturated fats..

    there are a reduced number of hydrogens, and a carbon double bond appears more.

  • what is a steriod?

    a family of lipids

  • what kind of structure do steroids have?

    A four ring structure consisting or testosterone, estrogen, and cholesterol

  • phospholipids have a...

    hydrophilic head and hydrophobic tails

  • phospholipids form...

    bilayers when interacting w water

    these bilayers have a cell membrane, are selectively permeable, and depend on acid saturation
