[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).

Biology (Grade 9): High School Learning: CELL WALL:
Cell Wall- A Protective layer surrounding the cell on the outside of the plasma membrane.
Cell Wall is only present in plant cell.
Cell Wall consists of 3 layers.
- Middle lamellla.- Outer wall.
- Primary Wall- Formed after middle lamella and consists of a skeleton of cellulose microfibrils, embedded in gel like matrix of pectic compounds, hemicellulose, and glucoprotein.

- Secondary Wall:
Formed after cell enlargement is completed , provides compression strength.

- Plasmodesmata: Connection between cells,A microscopic channels through the cell walls and lamella.

Cell Wall and Turgor:
- Cell Wall is made of neutral and charged polysacchrides absorbs H2O because it has a hypotonic environment.

- Increased H2O in the cell – Turgor Pressure. If a plant cell is turgid . it is very form , a healthy state in the most plant,If plant is flacid . it is isotonic solution.

Difference between CELL MEMBRANE and CELL WALL.
