[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).

042 – Biological Molecules

Paul Andersen describes the four major biological molecules found in living things. He begins with a brief discussion of polymerization. Dehydration synthesis is used to connect monomers into polymers and hydrolysis breaks them down again. The major characteristics of nucleic acids are described as well as there directionality from 3′ to 5′ end. Protein structure is describes as well as the structure of its monomers; amino acids. The carboxyl and amino ends of a protein are described. The major groups of lipids are included with a brief discussion of saturated, unsaturated and trans fats. Finally carbohydrates and their sugar monomers are discussed.
