This is a homopolymer built from 15 monomer #2. (2:42:08 PM) 2. Take a snapshot of your polymer built from different monomers, and drag it into the box below. This is my heteropolymer built from 5 of each monomer. (2:46:35…

Additionally, on the basis of types of monomer present in the polymeric chain, PHAs can be a homopolymer containing only one type of hydroxyalkanoate as the monomer unit like P(3HB), and P(3HHx). When more than one types of hydroxyalkanoate as monomer units are exist, they are often called heteropolymer such as poly(3-hydroxybutyrate-co-3-hydroxyvalerate), P(3HB-co-3HV), poly(3-hydroxyhexanoate-co-3-hydroxyoctanoate)…

molecules where monomers switch between adsorbing at the air-liquid interface, moving freely throughout the bulk solution, and aggregating to form micelles17. Below the CMC, monomers remain free in solution and adsorbing at the air-liquid interface. As the concentration of monomers increases, the interfacial free energy, a.k.a. surface tension, is reduced. The CMC is reached when the solution and interface are saturated with individual monomers. The addition of any subsequent monomers results in…

Kroger Brand diapers They are made from oxygen based compounds and it contains wheat based material for Kroger Brand chlorine free diapers, and are also based on a plant based lining Kroger Brand diapers are a very good choice for saving the ecosystem they are also fragrance free, has no smell, and it’s latex free. Huggies diapers are stretchy and are also adjustable and they protect up to 12 hours, huggies diapers also donate more than 130,000,000 diapers every single year you also have a…

made. It will also describe two groups of proteins and give some examples. Proteins (also called polypeptides, peptides or amino acids) are large polymers and main components of cells. They are produced by condensation reaction from amino acid monomers, therefore proteins are called condensation polymers. Each protein is formed by a unique sequence of 20 naturally occurring amino acids. However, not all the amino acids need to be find in one protein. Some can be found many times and some are…

plastics surround us every day. They possess unique characteristics; plastics can be tough and rigid yet still flexible and can be opaque yet transparent. The building blocks of plastics are small organic molecules often known as monomers, which then join to other monomers creating long molecule chains called polymers in a process called polymerisation (Nobelprize.org, 2016). Bioplastics are expected to become the future of synthetic material, because of the simple fact that they are…

The North Atlantic Ocean is a cold, inhospitable, and often ice-covered place. In spite of these harsh conditions, life continues to thrive in the cold, dark depths. The vast majority of these winter-resident species owe their success to various forms of anti-freeze proteins. Within Northern Atlantic resident species, there are six classes of Anti-Freeze Proteins (AFPs), generally categorized by molecular size, structure and effectiveness. AFPs are a remarkable exhibition of convergent evolution…

of many similar smaller molecules linked together. The individual smaller molecules are called monomers. When small organic molecules are joined together, giant molecules are produced. These giant molecules are fittingly known as macromolecules. Generally, most macromolecules are produced from a small set of about fifty monomers. Different macromolecules vary because of the arrangement of these monomers. Types of Macromolecules Macromolecules are categorized into four distinct groups:…

pinpoint the adequate time necessary to obtain the best yield and minimize the process cost. Figure 1 shows the acid value profile of Sn(Oct)2 catalyzed synthesis of PRA. As the reaction progressed, the hydroxyl group of one monomer reacted with carboxylic group of another monomer to form oligomer and then the chain was lengthened to polymer. This was indicated by a decrease in the acid value of from 164 to 52 (mg of KOH/g sample). It was first time demonstrated that Sn (Oct)2 can catalyze the…

its structure. The m immunoglobulin (IgM) is the first primary subclass which is produced due to primary response of the immune system. IgM is the second most dominate and abundant Ig in the serum. IgG is the most abundant in the serum. The IgM monomer has a structure with two heavy chains which are mu (m) and also two light chains the k and l. The IgM has no hinge region however it has a CH4…
