MCAT Bio1

AA, Protein, Enzyme

QuestionAnswer
Hydrolysis use water to break apart -cleave acid & heat (nonspecific) or protease (specific)
dehydration form molecule & release water
hydrophobic hate water
hydrophilic like water
eicosanoids -hormone, thromboxane, eukotrienes functio: regulate blood pressure, body temp, smooth muscle contraction, -transported via lipoprotein (VLDL,LDL,IDL,HDL) ↑ratio of lipid ↓protein density
Carbohydrate D vs L D: hydroxyl group on 5-carbon in Fischer projection points to right L: points to left
Carbohydrate Structure Cn(H2O)n -beta:alcohol UPWARD on anomeric carbon alpha:alcohol DOWNWARD on anomeric carbon anomeric carbon(C-1): C=OH C-5 attacks C=O to form hexagon structure w/CH2OH at C-5 (glucose)
Carbohydrate -store energy but not as much as lipids -form polysaccharides via dehudration and monosaccharides via hydrolysis
Glycosidic linkages linkages b/w sugars
ketose sugar w/aldehyde as most oxidized group
aldose sugar w/ketose as most oxidized group
epimer carbohydrate differs at one chiral carbon
anomer carbohydrate differs at anomeric carbon (C-1)
D-Fructose CH2OH │ C=O │ HO-C-H │ H-C-OH │ H-C-OH │ CH2OH
D-glucose H-C=O │ H-C-OH │ OH-C-H │ H-C-OH │ H-C-OH │ CH2OH
D-galactose H-C=O │ H-C-OH │ OH-C-H │ OH-C-H │ H-C-OH │ CH2OH
D-mannose H-C=O │ OH-C-H │ OH-C-H │ H-C-OH │ H-C-OH │ CH2OH
sucrose glucose-α-1,2-fructose
lactose galactose-ß-1,4-glucose
maltose glucose-α-1,4-glucose
cellulose plant cell wall fiber for humans
starch energy storage for plants
glycogen energy storage for animals
nucleotide composed of a nitrogeneous base, a five carbon sugar (deoxy or RN) & a phosphate group C2: H (DNA) or OH (RNA) C1: place of attachment for A, T, U, G, C C5: place of attachment for phosphate group
purine guanine, adenine (two cyclic ring)
pyrimidine cytosine, thymine, uracil (one cyclic ring)
how many H bonds b/w? Guanine & cytosine 3H bonds adenine & thymine/uracil 2H bonds
purines=pyrimidines #A= #T = #U #G = #C
5'-3" direction Top layer (parallel) 5"-3" direction Bottom layer (antiparallel) 3'-5' direction
RNA 1) carbon #2 -OH 2) Uracil instead of thymine 3) In cytoplasm & nucleus 4) single-stranded 5) mRNA (messneger) rRNA ( ribosomal) tRNA (transfer)
amino acid structure H2N-CR-COOH
nonpolar aa GAVLIFWMP
polar aa STCYNQ
basic aa DE
acidic aa HRK
glycine nonpolar [Gly] G achiral R=H
alanine nonpolar [Ala] A chiral R=CH3
valine nonpolar [Val] V chiral R=HC-(CH3)2
leucine nonpolar [Leu] L chiral R=CH2-CH-(CH3)2
Isoleucine nonpolar [ILE] I chiral R=H-C-(CH2CH3)(CH3)
phenylalanine nonpolar [Phe] F chiral R= CH2-(Benzene)
tryptophan nonpolar [Trp] W chiral R= CH2-(indole group) *look at slide
methionine nonpolar [Met] M chiral R= CH2-CH2-S-CH3
proline nonpolar [pro] P chiral causes kinks since H bond can't form HN-C-COOH | | \/

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
