PABA

PABA or Para-Aminobenzoic Acid is a compound that is considered a part of the B vitamins group. It is a non-protein amino acid that is widely distributed in nature and can be synthesized in the body. PABA is used in the synthesis of folic acid and is also used as a sunscreen.

History

PABA was first discovered in the 1940s and was initially used as a treatment for vitiligo, a skin condition that causes loss of pigmentation. However, it was later found to be ineffective for this purpose.

Uses

PABA is used in the manufacture of folic acid, which is essential for the body's production of DNA and RNA. It is also used as a sunscreen, as it can absorb ultraviolet (UV) light.

Side Effects

Some people may experience side effects from taking PABA, including nausea, vomiting, diarrhea, loss of appetite, and skin rash. In rare cases, it can cause liver damage.

Interactions

PABA can interact with certain medications, including sulfonamides, which are used to treat bacterial infections. It can also interact with methotrexate, a medication used to treat cancer and autoimmune diseases.
