|Biopolymers are chain-like molecules made up of repeating chemical monomers and could be very long in length. The prefix bio means that they are produced by living organisms and are biodegradable. Biopolymers are classified in three main groups, depending on the nature of the repeating unit they are made of: (i) polysaccharrides are made of sugars, (ii) proteins of amino acids, and (iii) nucleic acids of nucleotides. Scholarly peer review is the process of subjecting an author's scholarly work, research, or ideas to the scrutiny of others who are experts in the same field, before a paper describing this work is published in a journal. The work may be accepted, considered acceptable with revisions, or rejected. Peer review requires a community of experts in a given (narrowly defined) field, who are qualified and able to perform reasonably impartial review.
