Draw the structures of the dipeptides that can be formed from the reaction between the amino acids glycine and lysine.
Chem 1240 Notes Preferred Bonding of Row 2 Elements Atom # e- for Octet Valence e- e- Needed Bonds/Lone Pairs Needed H 2 1 1 1 Bond, 0 Lone Pairs C 8 4 4 4 Bonds, 0 Lone Pairs N 8 5 3 3 Bonds, 1 Lone Pair O 8 6 2 2 Bonds, 2 Lone Pairs F 8 7 1 1 Bond, 3 Lone Pairs What are the Steps for Determining Lewis Structures 1. Count the # of Valence Electrons(+) → Subtract 1 e- (-) → Add 1 e- 2. Draw the atoms. Then bonds. Then lone pairs 3. Use Formal Charge is necessary a. Formal Charge= Valence e- - # of Lone Pairs - 1/2(Bonded e-) Resonance Structures What are the T
