Background and Carbohydrates
How are macromolecule polymers assembled from monomers? How are they broken down?
To assemble a macromolecule polymer from monomers, the monomers must bond. This is a process known as a dehydration reaction, in which a water molecule is lost to form the bond. When this process occurs, each of the two bonded monomers provides part of the water molecule that was lost in the dehydration reaction: one contributes a hydroxyl group and the other a hydrogen. Dehydration reaction can take place over and over again, losing a water molecule every time, and forming a chain of monomers: a macromolecule. These macromolecules are disassembled by hydrolysis. This process is the inverse of a dehydration reaction: the covalent bond between the monomers is broken when water is added, a hydrogen attaching to one monomer and a hydroxyl group attaching to the other.
How can you tell a biological molecule is a carbohydrate?
Carbohydrates are sugars that contain carbon, hydrogen, and oxygen in a 1:2:1 ratio. They can be used for storage, structure, and energy. An example is glucose, with chemical formula C6H12O6.
Explain the relationship between monosaccharides, disaccharides, and polysaccharides.
All three are carbohydrates. Monosaccharides are the simplest carbohydrates and are classified as simple sugars with molecular formulas that are multiples of CH2O. Disaccharides are two monosaccharides bonded by a glycosidic linkage (a covalent bond formed by dehydration
