Peptide bonds are also referred to as what?

1. End bonds

2. Side bonds

3. Hydrogen bonds

4. Salt bonds

The correct answer is: End bonds

Peptide bonds refers to the covalent linkage between two amino acids in a protein chain. This bond forms between the amino group of one amino acid and the carboxyl group of another amino acid, resulting in a long chain of amino acids that makes up a protein. Therefore, it is more accurate to refer to peptide bonds as "end bonds" rather than "side bonds," "hydrogen bonds," or "salt bonds." These other options do not accurately describe the type of bond formed between amino acids and may cause confusion.
