Peptides are short polymers of amino acid which are linked by peptide bonds, the covalent chemical bonds formed between two motes when the carboxyl group of one patch reacts with the amino group of the other patch.
These are distinguished from proteins on the base of size, generally containing smaller than 50 monomer( AA) units. The shortest peptides are dipeptides, conforming of two amino acids which are joined by a single peptide bond.
There are also tripeptides, tetrpeptides, etc. Amino acids which have been incorporated into a peptide, is nominated remainders. Every peptide has a N- boundary and C boundary residue on the ends of the peptide.
Proteins are large organic composites that are made up of amino acids arranged in a direct chain and joined together by peptide bonds. Proteins are the most abundant factors of natural cells. They live performing similar as enzymes, hormones, structural element and immunoglobulin.
