Plastic, wood, and iron are all materials composed of atoms. Plastic is a synthetic material made up of long chains of molecules called polymers, typically derived from petrochemicals. Wood is a natural composite material made up of cellulose fibers held together by lignin, a complex organic polymer. Iron is a metallic element composed of iron atoms arranged in a crystalline lattice structure.
Polymers are compounds made of long chains of atoms, repeating units called monomers. These long chains can be natural or synthetic and have diverse properties depending on the type of monomers and the arrangement of the chains. Examples of polymers include plastics, proteins, and DNA.
Polymer made up of chains of amino acids, also called a polypeptide?
Iron is the heavier element from which steel is primarily made.
Yes & No. Iron is an Element with symbol Fe. Most Nails are an alloy of Iron and other metals and usually coated or anodized. However most nails will still have the properties of pure Iron, such as magnetism and oxidizes rapidly. Iron is an element. Nails are made using iron or iron alloys.
Iron.
Big, thick, handcuffs made of iron or steel. Sometimes they are connected to chains.
The subunit of hemoglobin is a protein molecule made up of four polypeptide chains. These chains consist of two alpha chains and two beta chains, each with a heme group that contains iron, which binds to oxygen.
Iron is used for chains because it is strong, durable, and resistant to corrosion. These properties make iron an ideal material for chains that need to withstand heavy loads and tough conditions without breaking or deteriorating quickly.
Usually some sort of metal, but the specific metal can vary. Many chains are made of steel, which is a mixture of iron and some other element, usually carbon.

how are steel chains made
Haemoglobin is made up of a protein called globin which is bound to a red pigment called heme (hence the name haemoglobin) Globin is made up of 4 chains (polypeptide chains) embedded inside each of which is a heme molecule, the latter has an iron atom (in ferrous state) in it. It is the iron atom which carries a molecule of oxygen. As there are 4 chains this means that there are 4 iron atoms which means that 4 molecules of oxygen can be carried by each haemoglobin. Globulin
Yes, iron chains are magnetic because iron is a ferromagnetic material. This means that it can be magnetized and is attracted to magnets.
Each hemoglobin molecule is made up of 4 poly-peptide chains. There are 2 alpha chains and 2 beta chains and each chain contains 1 iron-heme group which binds to an O2 molecule
chains of 20 basic amino acids
Iron pipes are made of iron.
