(GnRH) that is made of 10 amino acids
hyrotropin releasing hormone (TRH) :-it is synthesized as a 242-amino acid precursor polypeptide that contains 6 copies of the sequence -Glu-His-Pro-Gly-, flanked by di-basic peptides that are later processed through proteolysis to give the mature TRH molecule.
there is no fixed criteria but in-general
Amino acid :- Amino acids are molecules containing an amine group, a carboxylic acid group and a side-chain that varies between different amino acids NH2-CH(R)-COOH [ Where R is side chain).Their were 20 natural occuring amino acid and they are polymerize to give Peptide,Polypeptide and protein.
Peptide Bond :-A peptide bond is a covalent bond that is formed between two amino acid when the carboxyl group of one amino acid reacts with the amino group of the another amino acid. Simply [O=C-NH ], while amide bond is [O=C-NH2]
Peptide :- Peptides are short polymers of amino acids linked by peptide bonds. Here is confusion about no. of amino acid but mostly till 50 amino acid they were called peptide or polypeptide and if no. of amino acid is more then 50 it's called protien.
Polypeptide is same as peptide which use by some of the chemist to define peptide haviny amino acid more then 2 but less then 50 .
Protein :- Having amino acid more then 50 which were linked by peptide bond
