Amino Acids and Peptide Bonds
**Amino acids** are organic compounds that act as building blocks of proteins, while a peptide bond
Definition
Amino acids are organic compounds that act as building blocks of proteins, while a peptide bond joins amino acids together.
Formula / Key Relation
Two amino acids can join together. During this reaction: one loses `OH` another loses `H` and water forms. The new linkage is called a: peptide bond `–CO–NH–` General amino acid: `H₂N–CH(R)–COOH` Peptide bond: `–CO–NH–`
