Peptide is another name for protein, but is usually used for shorter amino acid chains.
No, a peptide bond is made between two amino acids to make polypeptides or proteins. Carbohydrates (sugars) do not make peptide bonds.
A pentapeptide, for example, is five amino acids conjoined by standard peptide bonds.
The links in a protein (amino acid) chain are called peptide bonds. These are any combination of amino acids in which the amino group of one acid is united with the carboxyl group of another.
The primary linkage of all protein structures; the chemical bond between the carboxyl groups and amino groups that unites a peptide
