Monomer

Suberin contains dicarboxylic acids so it is different from cutin and it also contain a big number of phenol containing compounds.Its monomers are C16-C28 ω-hydroxy fatty acids, alcohols ,C16-C26 α,ω-dicarboxylic acids, ferulate, very-long-chain fatty acids and, glycerol.

For my project, I chose to make an illustration. In the picture I have a breast cancer ribbon, a pot of boiling water, a prokaryote, a chromosome, a pedigree, and a factory to represent human impact, a flower to represent photosynthesis, a food chain, an energy pyramid, an embryo, humans evolving, a biomolecules chart, and the phases of mitosis. I drew a breast cancer ribbon because we talked about different types of cancer. There are many factors that go into the diagnosis of cancer. A lot of…

alpha-1,4 glycosidic linkages (Freeman). Amylose is a polymer with 500 to 2000 of the glucose subunits (Wang). The other form, amylopectin is branched and does contain the alpha-1,6 linkages. The branches of amylopectin occur in one of every thirty monomers (Freeman). Starch is an important component of plant foods, as its carbon and energy can be converted into use in the human digestive system. This is done using the enzyme amylase, which is found in the saliva, called ptyalin (Vance). Amylase…

Kevlor A synthetic material which has high tensile strength and used in manufacturing of tires and also as a reinforcement agent in manufacturing of protective parts like helmet etc…, HISTORY In 1930’s a chemical company called DuPont prepared commercially succeful super polyamide. Actually in 1964 Stephanie kwolek discovered kevlor in DuPont laboratory while doing research on the high performance chemical compounds. Kevlor is patented Stephanie kwolek in 1966 which is used by many police…

What are carbohydrates? Carbohydrates play a major role in our body, but many people don’t even know what they are. To show the true role of carbohydrates in the body you need to thoroughly break down every carbohydrate. CH2O is the general molecular formula for carbohydrates and it was once even called “hydrated carbon”. Each and every carbohydrate contains at least one carbon, hydrogen and oxygen atom, as well as being an organic compound. Though many people believe carbohydrates are bad for…

Sally the Cell Cells are constantly going through the cell cycle to duplicate themselves. The cell cycle consists of many different stages. Some stages take more time to complete than others. The phases of the cell cycle are gap phase 1 (G1), synthesis (S), gap phase 2 (G2), prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis. G1, S, and G2 make up interphase, while mitosis and cytokinesis make up the M phase. I, Sally the cell, am going to tell you about my journey in the…

Contamination is the presence of an unwanted impurity in a material.Contaminated water can be a source of deadly diseases, such as cholera and dysentery. Cholera an infectious disease that can cause severe watery diarrhea, dehydration, and death. Dysentery is an inflammation of the intestines, especially the colon, that often causes severe diarrhea with blood or mucus in the feces. Impurity is the quality or condition of being impure. particle is a minute fragment or quantity of matter.…

4.2.1. Material: Lead zirconate titanate (PZT) PZT is a short for lead zirconate titanate inorganic compound that has a chemical formula of Pb [ZrxTi1-x] O3 (0 ≤ x ≤ 1). PZT is made and composed of the two chemical elements lead and zirconium combined with the chemical compound titanate while formed under extremely high temperatures. The dielectric constant of PZT can range from 300 to 3850, depending upon orientation and doping. PZT possesses piezoelectric effect meaning that it changes shape…

5.4. Electrosensitive hydrogels Hydrogel swells in response to an electrical stimulus with a mechanism very similar to pH, experiences shrinkage, and bending. The major difference between electrical and pH stimulations is that the electric field moves mobile ions in order to regulate an ion concentration gradient through the hydrogel and the solution [54,55]. Polymeric networks containing ionizable groups can have important electrical behavior under an electric field. The electrosensitive…

Life is recognized by what we do. People, animals, plants and insects encompass properties such as order, regulation, growth and development, processing energy, responding to the environment, reproduction, and evolution. All living organisms exist with nonliving factors, as such, their interactions form an ecosystem. The two main processes of an ecosystem are the recycling of chemical nutrients and the flow of energy. Cells are a component of all living organisms and essentially are life’s…
