Functional Groups Flashcards
1
Q
Hydroxyl
A
O-H polar bc O is electronegative forms H bonds acidic H donates H+ alcohols
2
Q
Carbonyl
A
C=O ketoses= sugars w/ ketone groups aldoses=sugars w/ aldehydes polar basic
3
Q
Carboxyl
A
OH-C=O (H can be donated)
acidic bc donates an H
side chains of Amino acids
4
Q
Amino
A
H-N-H (H+ can accept accept H)
basic because it accepts an H
amino acid
5
Q
Sulfhydryl
A
S-H
helps stabilize proteins by forming disulfide bonds
cystine amino acids
6
Q
phosphate
A
PO4 important in energy transfer - charge allows it to react w/ O hydrophilic (polar) phospholipid heads
7
Q
Methyl
A
CH3
hydrophobic (non polar)
side chain of amino acid
