[What is Huperzine A]
Huperzia is a type of moss that grows in China. It is related to club mosses (the Lycopodiaceae family) and is known to some botanists as Lycopodium serratum . The whole prepared moss was used traditionally. Modern herbal preparations use only the isolated alkaloid known as huperzine A. Huperzine A is an alkaloid found in huperzia that has been reported to prevent the breakdown of acetylcholine, an important substance needed by the nervous system to transmit information from cell to cell. Animal research has suggested that huperzine A’s ability to preserve acetylcholine may be greater than that of some prescription drugs. Loss of acetylcholine function is a primary feature of several disorders of brain function, including Alzheimer’s disease . Huperzine A may also have a protective effect on brain tissue, further increasing its theoretical potential for helping reduce symptoms of some brain disorders.
[Function] Used in alternative medicine, huperzine A has been found to act as a cholinesterase inhibitor, a type of medicine used to prevent the breakdown of acetylcholine (a chemical essential to learning and memory).
Not only used as a treatment for Alzheimer’s disease, huperzine A is also said to enhance learning and memory and to protect against age-related cognitive decline.
In addition, huperzine A is sometimes used to boost energy, increase alertness, and aid in the treatment of myasthenia gravis (an autoimmune disorder that affects the muscles).
Carbohydrates: Polyhydroxy aldehyde or ketone called carbohydrate [(CH2O)n]. Carbohydrates are technically hydrates of carbon. Carbohydrates perform various roles in living organisms. Polysaccharides serve for the storage of energy constituents (e.g. starch and glycogen) and as structural components (e.g. cellulose in plants and chitin in arthropods).
Natural saccharides are generally built of simple carbohydrates called monosaccharides with general formula (CH2O)n where n is three or more. The open-chain form of a monosaccharide often coexists with a closed ring form where the aldehyde/ketone carbonyl group carbon (C=O) and hydroxyl group (–OH) react forming a hemiacetal with a new C–O–C bridge.
Epimer: In stereochemistry, epimer refers to one of a pair of stereoisomers. The two isomers differ in configuration at only one stereogenic center. D-glucose and D-galactose are epimer, differ only in their configuration at C-4 while in mannose at C-2.

Description: NIH Director’s Wednesday Afternoon Lecture Series
Dr. Fraser’s current research interests are focused oncharacterization of the structure and function of the microbial communitiesthat are found in the human environment, as part of the NIH-funded HumanMicrobiome Project, including projects specifically focused on obesity,metabolic syndrome, inflammatory bowel disease, the interactions between thehuman immune response and the gut microbiome, and the impact of probiotics onthe structure and function of the intestinal microbiome.
