Final answer:
A peptide bond is the amide bond that occurs between the amine nitrogen of one amino acid and the carboxyl carbon of another amino acid. This bond is responsible for joining amino acids together and forming larger molecules such as peptides and proteins.
Step-by-step explanation:
A peptide bond is the amide bond that occurs between the amine nitrogen of one amino acid and the carboxyl carbon of another amino acid. This bond is responsible for joining amino acids together and forming larger molecules such as peptides and proteins. The peptide bond results in the formation of a dipeptide, which is a molecule composed of two amino acids joined together.
To convert moles of potassium to potassium atoms, you can use Avogadro's number, which is approximately 6.022 x 10^23 atoms/mol. In this case, you have 18.59 mol of potassium. Multiplying this by Avogadro's number gives you approximately 1.12 x 10^23 potassium atoms.
