Wintergreen headache, fever, sore throat, and various aches and pains. These therapeutic effects likely arose because the primary metabolite of methyl salicylate is salicylic acid, a proven NSAID that is also the metabolite of acetylsalicylic acid, commonly known as aspirin. During the American Revolution, wintergreen leaves were used as a substitute for tea, which was scarce. Wintergreen is a common flavoring in American products ranging from chewing gum, mints, and candies to smokeless tobacco such as dipping tobacco (American "dip" snuff) and snus. It is a common flavoring for dental hygiene products such as mouthwash and toothpaste. It is a component
Neuraminic acid considerably: acetyl, lactyl, methyl, sulfate and phosphate groups have been found. The name "neuraminic acid" was introduced by German scientist E. Klenk in 1941, in reference to the brain lipids from which it was derived as a cleavage product. The symbol commonly used for neuraminic acid is Neu, and the residue is typically found with additional chemical modifications in biological systems. As a family, these residues are known as sialic acids. For example, "N"-acetylneuraminic acid, Neu5Ac, is typical in human glycoproteins. Among their many biological functions, these structures are substrates for neuraminidase enzymes which cleave neuraminic acid residues. Human flu
