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.
Amino acids combine in the synthesis of the polypeptide chains that make up proteins. Glycerol (a trihydric alcohol) and three fatty acids combine to form a lipid. Monosaccharides combine to form polysaccharides (complex carbohydrates). Nucleotides combine to form a strand of a nucleic acid.plit and merge into it. Answered by The Community. Making the world better, one answer at a time. lipids do not have monomers, they are made of fatty acid chains and a glycerol molecule, unless it is a phospholipid, they are made of fatty acids and a phosphate head.
