Moreover, some of the most complex molecules within life forms contain carbon bonded to other elements, such as oxygen, hydrogen, and nitrogen. For this reason, life on Earth is known as carbon-based, or life that contains building blocks made up of combinations of carbon and other elements...
The chlorophyll molecule consists of a centralmagnesiumatom surrounded by a nitrogen-containing structure called aporphyrin ring; attached to the ring is a long carbon–hydrogen side chain, known as aphytolchain. Variations are due to minor modifications of certain side groups. Chlorophyll is remarkab...
Plants, aside from having chlorophyll and other pigments, also have in their cell a structure known as the cell wall. Plants, compared to animals, can also use inorganic forms of nitrogen, which makes them not need an external source of protein. ...
Human body parts and their functions can be best understood by understanding the organization of the body. All living things are made of six main elements: Carbon Hydrogen Nitrogen Oxygen Phosphorus Sulfur These elements create molecules that create the basic structures of the body. The body is hi...
What are factors affecting the balance of the ozone layer? What is a radial wave function? Explain why gases always occupy the entire container they are in but solids and liquids do not. How does nitrogen monoxide (NO) function in the body to regulate blood pressure? What is the ...
The building block, or monomer, of all nucleic acids is a structure called a nucleotide. A nucleotide has three parts: phosphate, deoxyribose sugar, and a nitrogen base.There are four different nucleotides that make up a DNA molecule, each differing only in the type of nitrogenous base. ...
It is the preferred source of fuel for most living things and is often referred to as the "molecular unit of currency." The Structure of ATP TheATP molecule has three parts: 1. Theadenosinemodule is a nitrogenous base made up of four nitrogen atoms and an NH2 group on a carbon compound...
We are asked to believe that the concourse of atoms, of iron, and of nitrogen, and of other sorts of chemical elements, into the form of the ship, of its armour, of its guns, of its engines, of its ammunition, of its stores of food,—that this concourse was purely the outcome of...
phosphate group varies from molecule to molecule; for example, it can be phosphatidylcholine, a which includes a nitrogen-containing component. It is hydrophilic because it has an uneven distribution of charge (i.e., is polar), just like water, so the two "get along" in close microscopic ...
