Detailed explanation-1: -A polypeptide is a combination of peptides, which are made of amino acids. There are twenty amino acids, each of which has an N-terminal with an amino group and a C-terminal with a carboxyl group. Likewise, a polypeptide has an N-terminal with an amino group and a C-terminal with a carboxyl group.
Detailed explanation-2: -In vivo, each amino acid is added to the amino-terminal of one amino acid to form a peptide chain. When there are greater than 20 amino acids, the peptide is an unbranched chain deemed a polypeptide.
Detailed explanation-3: -A dipeptide has two amino acids. A tripeptide has three amino acids. A tetrapeptide has four amino acids.
Detailed explanation-4: -Proteins are built from a set of only twenty amino acids, each of which has a unique side chain. The side chains of amino acids have different chemistries.
Detailed explanation-5: -Each polypeptide consists of a chain of amino acids linked together by covalent (peptide) bonds.
