Polyamide A polyamide is a macromolecule with repeating units linked by amide bonds.Polyamides occur both naturally and artificially. Examples of naturally occurring polyamides are proteins, such as wool and silk.Artificially made polyamides can be made through step-growth polymerization or solid-phase synthesis yielding materials such as nylons, aramids, and sodium poly(aspartate) . polyamide is a macromolecule with repeating units linked by amide bonds.

umami Umami is a pleasant savoury taste produced by glutamate and ribonucleotides, chemicals which occur naturally in many foods including meat, fish and dairy products. Umami is subtle and not generally identified by people when they encounter it, but blends well with other tastes to intensify and enhance flavours.

Polyester Polyester is a synthetic fiber derived from coal, air, water, and petroleum. Developed in a 20th-century laboratory, polyester fibers are formed from a chemical reaction between an acid and alcohol.In this reaction, two or more molecules combine to make a large molecule whose structure repeats throughout its length.he principle ingredient used in the manufacture of polyester is ethylene, which is derived from petroleum. In this process, ethylene is the polymer, the chemical building block of polyester, and the chemical process that produces the finished polyester is called polymerization.

Aramid Aramid, in full aromatic polyamide, any of a series of synthetic polymers (substances made of long chainlike multiple-unit molecules) in which repeating units containing large phenyl rings are linked together by amide groups. Amide groups (CO-NH) form strong bonds that are resistant to solvents and heat.

Loperamide Loperamide, sold under the brand name Imodium among others, is a medication used to decrease the frequency of diarrhea. It is often used for this purpose in gastroenteritis, inflammatory bowel disease, and short bowel syndrome.operamide was first made in 1969 and used medically in 1976. It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system. It is sold as a generic medication and is not very expensive.

What is acrylamide? Acrylamide is a chemical used primarily as a building block in making polyacrylamide and acrylamide copolymers. Polyacrylamide and acrylamide copolymers are used in many industrial processes, such as the production of paper, dyes, and plastics, and in the treatment of drinking water and wastewater, including sewage. They are also found in consumer products, such as caulking, food packaging, and some adhesives.

Polyamide The resulting polymers are known as polypeptides or proteins. For the industrial production of synthetic polyamides with at least one aliphatic monomer (nylon polymers), the amide link is produced from the condensation reaction of an amino group and a carboxylic acid group, water is eliminated.

Polysaccharides Also known as glycan, polysaccharide is a carbohydrate that can be broken up into two or more molecules of mono-saccharides by means of hydrolysis. In fact, polysaccharide is the basic appearance in which majority of the carbohydrates are found naturally. The molecular structure of polysaccharides may be either linear or branched.

- Polyamide. A polyamide fibre is defined by BISFA as being a fibre composed of linear macromolecules having in the chain recurring amide linkages, at least 85% of which are joined to aliphatic or cycloaliphatic units.There are many polyamide fibres made but only two, described below, are made in significant quantities.o produce fibres from the polyamide polymers the molten polymer is pumped through spinneret holes at a temperature approaching 300 degrees C to form filaments that are cooled and solidified in a quench air stream.
