Flashcards in 10-30-13 Amino Acids Deck (12):
1

T/F amino acids generat energy, used for protein synthesis

T

2

All amino acids are chiral except (tryptophan/glycine) and also doesn't have a (alpha/beta) version

glycine

beta

3

The (amine/carboxyl/R) group is what gives unique properties to proteins

R group

4

T/F amino acids help in the synthesis of Heme
Purines
Melanin
Pyrimidines
New proteins

T

5

(alpha/beta)amino acids means the amino group is attached to the second carbon away from the carboxyl group

beta

6

(alpha/beta)amino acids means the amino and carboxyl group is attached to the same carbon atom (called the  carbon)

alpha

7

Only the (L/D) isomer and the (alpha/beta)form is used in natural proteins

L alpha

8

A protein synthesized with only (L/D) amino acids called a racemic protein

D

9

T/F enantiomers are resistant to enzymatic degradation therefore making it easier to crystallize pr,proteins for structural determinations

T

10

(L/D) amino acids govern stationary phase cell wall remodeling in bacteria

D

11

(L/D) amino acids appear to modulate synthesis of peptidoglycans
-influence peptidoglycan compostion, amoutn and strenght
-Via incorporation into polymer and regulation of synthetic enzymes

d

12

(D-Met/D-Ala/D-Leu/D-Val) (Vibrio cholerae) and (D-Tyr/D-Phe/D-Arg) (Bacillus subtilis) appear to modulate synthesis of peptidoglycan
-pick two for each

D-Met and D-Leu (Vibrio cholerae) and D-Tyr and D-Phe (Bacillus subtilis)
