Step-by-Step Text Solution:1. Definition of Polymers: - Polymers are large molecules made up of repeating structural units called monomers. These monomers are simple molecules that combine under specific co

Polymers are formed when several single units of molecules (referred to as monomers) are joined together by a chemical bond. In the case of glucose, a simple sugar monomer, or what we can specifically call a monosaccharide (mono-single, saccharide - sugar), it combines with other glucose ...
first paragraph 第一段 what are polymers? For one thing, thy are complex and giant molecules and are different from low molecular weight compounds like ,say, common salt. To contrast the difference, the molecular weight of common salt is only 58.5, while that of a polymer can be as high ...
As an example, a gaseous compound called butadiene, with a molecular weight of 54, combines nearly 4000 times and gives a polymer known as polybutadiene (a synthetic rubber) with about 200000 molecular weight. The low molecular weight compounds from which the polymers form are known as ...
In our daily life, polymers are called as plastic, rubber, andfiber. And those are also three categories of polymer materials.We can see these three kinds of polymer materialsevery day.Fibers are the most closest to us; almost all our clothes are madefrom fibers. On the tags in our ...
What are glucose polymers called? What is the main sugar used by cells for energy? What does sugar do to endothelial cells? What is the difference between ATP and carbohydrate? Which of the following are carbohydrates? Select all that apply. Glucose C_{6}H_{12}O_{6} Amylose Amylase Lact...
To answer the question "What is the unit called from which polymers are made?", we can break down the explanation into clear steps:1. Understanding Polymers: - Polymers are large molecules made up of many smaller units. The
Polymers (“poly” = many; “mer” = unit) are long-chain molecules that consist of “many units”, i.e., repeating sections of monomers --- like links in a chain --- e.g., polyethylene would consist of many ethylene (-CH2-CH2-) units. These monomers can be added one to another...
Natural polymer examples include cellulose, silk, wool, DNA, proteins, and latex from a rubber tree plant. Polyurethane, polyethylene, nylon, and vulcanized rubber are synthetic, or man-made, polymers. Polymers are formed by a process called polymerization, a chemical reaction in which molecules ...
