Amino Acids Basics

Amino Acids Basics

1. peptide bonded backbone

   • same in all amino acids
   • hydrophilic
     • water loving

2. R groups

   • side chains (variants)
   • make each amino acid unique
   • important in protein folding
     • possitively charged bond with negative
     • negatively charged bond with positive

3. Held together by peptide bonds

   • n-terminus
     • first part formed at beginning
   • c-terminus
     • last formed at end
   • covalent
     • share electrons

4. chemistry terms

   • nonpolar
     • hydrophobic inside
       • phospholipid inside
   • polar
     • hydrophilic outside
       • phospholipid outside
   • covalent bonds
     • polar
       • O-H, N-H, N-C, O-C
     • nonpolar
       • C-C, C-H
