- Polyamides - Nylon: Polyamides such as nylon are also condensation polymers. The formation of a polyamide follows the same procedure as in the synthesis of a simple amide. Again, the only difference is that both the amine and the acid monomer units each have two functional groups - one on each end of the molecule.

Basal ganglia The substantia nigra is the source of the striatal input of the neurotransmitter dopamine, which plays an important role in basal ganglia function. The subthalamic nucleus receives input mainly from the striatum and cerebral cortex, and projects to the globus pallidus.Currently, popular theories implicate the basal ganglia primarily in action selection; that is, it helps determine the decision of which of several possible behaviors to execute at any given time.he largest component, the striatum (dorsal and ventral), receives input from many brain areas beyond the basal ganglia, but only sends output to other components of the basal ganglia. The pallidum receives input from the striatum, and sends inhibitory output to a number of motor-related areas.

What is a polysaccharide? polymers consisting of chains of monosaccharide or disaccharides units Groups of sugar molecules linked together make larger molecules as well as long chain polymers. These … are called polysaccharides. Polysaccharide are large numbers of carbohydrates found in or made by living organisms and microbes.

Polysaccharides Polysaccharides Definition and Structure. Polysaccharides [Greek poly = many; sacchar = sugar] are complex carbohydrates, composed of 10 to up to several thousand monosaccharides arranged in chains. The most common monosaccharides that appear as parts of polysaccharides are glucose, fructose, galactose and mannose. Picture 1.

- What does polydispersity mean? The term polydispersity has multiple meanings that are dependent upon the context of its use. In the area of polymer chemistry, polydispersity is defined as the weight average divided by the number average molecular weight (M w /M n), and is used to give the researcher an idea of the breadth or width of the molecular weight distribution.

- Acrylamide is a chemical compound that occurs as a solid crystal or in liquid solution. Its primary use is to make polyacrylamide and acrylamide copolymers. Trace amounts of the original (unreacted) acrylamide generally remain in these products. Polyacrylamide and acrylamide copolymers are used in many industrial processes, including production of paper, dyes, and plastics, and the treatment of drinking water, sewage and waste. They are also present in consumer products such as caulking, food packaging and some adhesives.
