Chapter 3 :. The Molecules of Life. Organic Compounds. Compounds in the natural world that contain the element carbon (bonded to hydrogen). Hydrocarbons – contain only C & H (ex. CH 4 ) Most also include oxygen and some also have nitrogen, phosphorus and sulfur.
The Molecules of Life
The diagram below shows two amino acids, the monomers of a protein. Draw these amino acids in your notes. What has to happen for these two molecules to combine? (What must be done for bonds to be made in biological systems?) Represent this process by redrawing the amino acids bonded together and drawing the bi-product formed.
In living systems, bonds are made by removing water. An –OH from one molecule and an –H from the other combine to form water. The removal of these atoms provides “space” for the new bond to form, by leaving atoms with unfilled valence shells.
Is fructose an aldose or a ketose?
Is glucose an aldose or a ketose?
