Biopolymers and peristence length

a) In this case (one polymer) the new persistence length will be higher than the old one (of the two polymers). If the contour lengths are different it means that at a certain distance one of the two polymers will slip and then i will only have 1 polymer left. Supposing you have two or more polymers, with the same persistence length but varying contour lengths, that are firmly attached in a parallel way upon e. g. a wall. The bead on the left is stationary, and the polymers are part of the cell wall on the right and suppose that the wall starts moving towards the right direction. I would really need your help with the following problem.

Biopolymers film

Safe aqueous glucans film, ie consisting only of glucose unit for different applications.





Dow and Mitsui to Produce Biopolymers from Sugar-Cane Based Ethanol

By Cameron Chai

Mitsui of Tokyo, Japan and the Dow Chemical Company have formed a joint venture and signed a Memorandum of Understanding (MOU) to deliver sustainable products to the international versatile, high-performance hygiene, medical and packaging markets. This joint venture is Dow’s largest investment in Brazil.

As per the terms of the agreement, Mitsui will acquire 50% equity interest in the sugar cane growing process of Dow in Brazil. The initial scope of the partnership includes manufacturing sugar cane-derived ethanol as a renewable source for feedstock, offering innovative, biomass-based feedstocks to Dow.

Mitsui and Dow will feature a large integrated facility to produce biopolymers manufactured from clean ethanol extracted from sugar-cane. The project aims at formulating low carbon solutions to deal with the pressing issues like energy demands and climate variations.

Biopolymers manufactured at this facility will be a renewable option resulting in the manufacture of high-performance plastics with a small carbon footprint and an immediate substitute to suit the medical, packaging and hygiene markets. These Biopolymers will deliver clients a sustainable environment with the same performance.

biopolymers?

Im doing an assignment on biopolymers and im a little confused.

Is polylactic acid a biopolymer or is it a source for production of biopolymers.

I need to choose a biopolymer produced through the use o bacteria for my assignment.


Biopolymers are a class of polymers produced by living organisms. Starch, proteins and peptides, DNA, and RNA are all examples of biopolymers, in which the monomer units, respectively, are sugars, amino acids, and nucleic acids.
Polylactic acid

What are some examples of metastable biopolymers?

I know 2 are DNA and polypeptides, but I need to know 2 more for a test and I can't find the answer anywhere. Please answer if you know.


glycogen/ starch (carbohydrates)
