- Amino Acids
- General formula
- RCH(NH2)COOH
- 2aminoethanoic acid is also known as
- GLYCINE
- The creation of a dipeptide or polypeptide is known as
- a condensation reaction
- You break down amino acids by
- hydrolysis reaction
- Amino acids are joined together by
- Peptide bonds
- Zwitterion
- An internal salt formed when the caboxyl group and amino group interact
- Zwitterion formation
- A proton is transferred for carboxyl to the amine group
- Isoelectric point
- The pH value at which the amino acid exists in a zwitterion exists
- Zwitterion charge
- no overall charge because the positive N and negative O balance out
- In acidic conditions Zwitterions act as
- a base (proton acceptor)
- In alkaline conditions a Zwitterion acts as
- An acid (proton donor)
- Amino acids act as
- both an acid and a base because of the acidic carboxyl and the amine group
- General formula
- RCH(NH2)COOH
