Biopolymers are an alternative to petroleum-based polymers (traditional plastics). (Bio)polyesters have properties similar to traditional polyesters. Starch-based polymers are often a blend of starch and other plastics (e.g PE), which allows for enhanced environmental properties. Polyesters. Biopolymer type. Price. (DKK/kg).
Products and Applications of Biopolymers. 4. 2. GA sources and processing. Acacia senegal and Acacia seyal trees are the main sources of GA. These species grow naturally in the semi-arid sub-Saharan regions of Africa. There are over 1000 species of acacia and a summary of their botanical classification was reported by
Biopolymers are polymers produced by living organisms; in other words, they are polymeric biomolecules. Since they are polymers, biopolymers contain monomeric units that are covalently bonded to form larger structures. There are three main classes of biopolymers, classified according to the monomeric units used and

Biopolymer History; Example of Biopolymer; Biopolymer Classification; Biopolymer Types; Biopolymer Structure; Biopolymer Uses; Biopolymer Environmental Benefits; Difference between Polymer and Biopolymer. Rising concern about escalating price of fossil fuel and their impact on environment
Biopolymers: introduction. Proteins (muscles, skin, hair, nails, enzymes). DNA (information storage polymer). Carbohydrates (energy storage, structural components). Biopolymers are polymers that bio-degrade with the action of micro-organisms, heat and moisture. There is no specific standard for biodegradation.

Monosaccharides. • 20 natural kinds, mostly in 2 types. – Pentoses (5 carbons – ribose). – Hexoses (6 carbons – glucose, fructose). • Hexoses can have either 5 or 6-member rings. • All have an ether O in the ring. – Ether is the starting point for numbering. Fructose. (C. 6. H. 12. O. 6. )
Book summary: Biopolymers are polymers produced by living organisms. This book comprehensively reviews and compiles information on biopolymers in 30 chapters which cover occurrence, synthesis, isolation and production, properties and applications, modifi cation, Sorry, there is no online preview for this file type.
We'll skip carbohydrates and turn to: Proteins and nucleic acids. Note: Your textbook covers nucleic acids in much more detail than proteins, so we will spend most time on proteins. Biopolymers Alanine has no symmetry plane and can therefore exist in two forms—a “right-handed" form and a “left- handed" form. Propane
