Biopolymers Research
Open Access

Biopolymers are natural polymers produced by the cells of living organisms. Biopolymers correspond of Monomeric units that are covalently clicked to form larger motes. There are three main classes of Biopolymers, classified according to the monomers used and the structure of the biopolymer formed Polynucleotide’s, polypeptides, and polysaccharides. Polynucleotide’s, similar as RNA and DNA, are long Polymers composed of 13 or further nucleotide monomers [1]. Polypeptides and proteins are polymers of Amino acids and some major exemplifications include collagen, actin, and fibrin. Polysaccharides are Direct or fanned polymeric carbohydrates and exemplifications include bounce, cellulose and alginate. Other exemplifications of biopolymers include natural rubbers (polymers of isoprene), suberin and lignin (Complex polyphenolic polymers), cutin and cutan (complex polymers of long- chain adipose acids) and Melanin. Biopolymers have operations in numerous fields including the food assiduity, manufacturing, packaging, and biomedical engineering.

The below listed are Some Common Biopolymers and their Uses

Collagen: Collagen is the primary structure of invertebrates and is the most abundant protein in Mammals. Because of this, collagen is one of the most fluently attainable biopolymers, and used for numerous exploration purposes. Because of its mechanical structure, collagen has high tensile strength and is a non-poisonous, fluently absorbable, biodegradable and biocompatible material [2]. Thus, it has been used for numerous medical operations similar as in treatment for towel infection, medicine delivery systems and gene remedy.

Silk fibroin: Silk Fibroin (SF) is another protein rich biopolymer that can be attained from different Silk worm species, similar as the mulberry worm Bombyx mori. In discrepancy to collagen, SF has a lower tensile strength but has strong tenacious parcels due to its undoable and stringy protein composition. In recent studies, silk fibroin has been plant to retain antiagulation parcels and platelet adhesion. Silk Fibroin has been also plant to support stem cell proliferation in vitro.

Gelatin: Gelatin is attained from type I collagen conforming of cysteine, and produced by the partial hydrolysis of collagen from bones, apkins and skin of creatures. There are two types of gelatin, Type A and Type B. Type A collagen is deduced by acid hydrolysis of collagen and has18.5 nitrogen. Type B is deduced by alkaline hydrolysis containing 18 nitrogen and no amide groups [3]. Elevated temperatures beget the gelatin to melts and exist as coils, whereas lower temperatures affect in coil to helix metamorphosis. Gelatin contains numerous functional groups like NH2, SH, and COOH which allow for gelatin to be modified using nanoparticles and biomolecules. Gelatin is an Extracellular Matrix protein which allows it to be applied for operations similar as crack dressings, medicine delivery and gene transfection.

Bounce: Bounce is an affordable biodegradable biopolymer and riotous in force. Nano filaments and microfibers can be added to the polymer matrix to increase the mechanical parcels of bounce perfecting pliantness and strength. Without the filaments, bounce has poor mechanical parcels due to its perceptivity to moisture. Starch being biodegradable and renewable is used for numerous operations including plastics and pharmaceutical tablets.

Cellulose: Cellulose is veritably structured with piled chains that affect in stability and strength. The strength and stability comes from the straighter shape of cellulose caused by glucose monomers joined together by glycogen bonds [4]. The straight shape allows the motes to pack nearly. Cellulose is veritably common in operation due to its abundant force, its biocompatibility, and is environmentally friendly. Cellulose is used extensively in the form of Nano-fibrils called Nano-cellulose. Nano-cellulose presented at low attention produces a transparent gel material. This material can be used for biodegradable, homogeneous, thick flicks that are veritably useful in the biomedical field.

Alginate: Alginate is the most riotous marine natural polymer deduced from brown seaweed. Alginate biopolymer operations range from packaging, cloth and food assiduity to biomedical and chemical engineering. The first ever operation of alginate was in the form of crack dressing, where it’s gel-suchlike and spongy parcels were discovered [5]. When applied to injuries, alginate produces a defensive gel sub caste that’s optimal for mending and towel juvenescence, and keeps a stable temperature terrain. Also, there have been developments with alginate as a medicine delivery medium, as medicine release rate can fluently be manipulated due to a variety of alginate consistence and stringy composition.
