See a picture of the spine. Upper and middle back pain is not as common as low back pain or neck pain, because the bones in this area of the back don't flex or move as much as the bones in your lower back or neck.
Fats are a class of lipids containing two kinds of monomers, fatty acids and glycerol. Glycerol is a three carbon biomolecule containing three hydroxyl groups, one bonded to each carbon atom. Dehydration synthesis creates an ester linkage between the carboxyl group of fatty acids and a hydroxyl group in glycerol.
Monomers are the building blocks of large macromolecules, or any molecule chain created through condensation reactions. These are the polymers, three or more monomers bonded together. In the category of carbohydrates, there are monosaccharides, disaccharides, oligosacchaides, and polysaccharides.he monosaccharides are just a single carbon ring (in the natural aqueous environment of an organism). The monosaccharides include glucose, fructose, and galactose. The disaccharides are two carbon rings bonded together by a glycosidic linkage in a condensation (dehydration) reaction, which removes a molecule of water.
