RNA
Cellulose molecules have a linear shape, with a repeating chain of glucose units bonded together.
Amino Acids
A molecule weighing 22 units can be constructed with one atom of carbon and four atoms of hydrogen. This is a methane molecule that normally would weigh 16 units. However, if two hydrogens are deuterium (2 units each) and two atoms of hydrogen are tritium (3 units each), the molecular weight comes out to 22 units.
The backbone of the DNA molecule is composed of alternating sugar (deoxyribose) and phosphate units. These sugar-phosphate units are connected by phosphodiester bonds to form the backbone of the DNA strand.
These are solids formed from an infinite number of formula units (basic units) of a chemical compound.
A protein molecule has a long helical structure made of amino acid units with distinctive R-groups. The R-groups contribute to the unique 3D structure and function of the protein.
Iodine forms a complex with the helical structure of starch, causing a color change to blue or black. This occurs due to the formation of inclusion compounds where iodine molecules fit into the spaces between glucose units in the starch molecule.
