What does complex molecule mean?

What does complex molecule mean?

A complex is a molecular entity formed by loose association involving two or more component molecular entities (ionic or uncharged), or the corresponding chemical species. The bonding between the components is normally weaker than in a covalent bond.

What is an example of a complex molecule?

Hemoglobin is a large complex molecule composed of heme, an iron-based part to which oxygen can bind, and globin, a structural protein chain. Proteoglycans are complex molecules defined as a protein to which one or more linear (typically sulfated) carbohydrate chains (glycosaminoglycans) are attached.

What is a complex molecule called?

The term “complex organic molecules” is used differently in astronomy and chemistry. In chemistry, “complex organic molecules” refer to polymer-like molecules such as proteins. Proteins are typical complex organic polymers with well-defined three-dimensional shapes, composed of 20 kinds of amino acids.

What is complex organic molecules?

Organic compounds are any molecules that are composed of the element carbon. The four main groups of carbon molecules of life are the most complex organic compounds: proteins, carbohydrates, lipids, and nucleic acids. All complex organic molecules are polymers. Essentially, polymers are complexes of monomers.

What is the meaning of complex in biology?

Complex. complicated, not simple. Origin: L. Complexus = woven together, encompassing.

What is a complex atom?

A complex is a species in which the central atom is surrounded by a group of Lewis bases that have covalent bonds to the central atom. Thus, the Lewis bases, or ligands, in complexes have electron pairs they can share with the central atom. …

What is the most complex molecule?

But i-propyl cyanide is the largest and most complex organic molecule found to date – and the only one to share the branched atomic backbone of amino acids. “The idea is to know whether the elements that are necessary for life to occur… can be found in other places in our galaxy.”

Where are complex molecules formed?

In polymerization, complex molecules are formed when monomers join together. The product formed by the joining of monomers is called a macromolecule or polymer. Polymers are exemplified by the carbohydrate compounds starch and glycogen. Carbon’s ability of covalent bonding allows its compounds to form large polymers.
