Flashcards in Biochemistry Intro Deck (27):
1

Acid + Alcohol

Ester

2

Acid + Thiol/Sulfhydril

Thioester

3

Acids + Amines

Peptides or Amides

4

Phosphoric Acid + Alcohol

Phosphomonoesters

5

Condensation of 2 Acids

Anhydride

6

Release of O2 from hemoglobin requires.....

Histidine

7

Acids

donate protons

8

Bases

Accept protons

9

Covalent Bonds

Sharing of electrons

10

Non-Polar Covalent Bonds

electrons shared equally

11

Polar Covalent Bonds

Atom with greater electronegativity has greater pull; electrons shared unequally

12

C : (O+N) = 1-3

Very Soluble

13

C : (O+N) = 3-6

Soluble

14

C : (O+N) > 6

Insoluble

15

Phosphate Transfer

Transferring a phosphate group from ATP to another molecule
Forms phosphomonoester bonds
Process aided by kinases

16

Phosphate Cleavage

Phosphatases hydrolyze phosphomonoester bonds to remove a phosphate group

17

Rearrangement Reaction

Change in structure results in a new compound

18

Condensation Reaction

Removing 2H and 1O to make a single new compound + water

19

Hydrolysis

Adds H20 and splits apart a compound

20

Oxidation-Reduction Reactions

OIL RIG (electrons)

21

Dehydrogenase

Removes 2H from substrate
in oxidation-reduction

22

Oxidase

promotes the gain of O in oxidation-reduction

23

Reductase

Add 2H to substrate

24

Lower pKa =

Stronger Acid

25

pH = pKa

Conj. Base = Acid

26

pH > pKa

Conj. Base > Acid

27

pH

Conj. Base
