PABA

Construct a chemical structure model of the sunscreen PABA from Genuine Molymod Model Parts by Indigo

What is PABA?

PABA, (aka para amino benzoic acid) is the primary ingredient in sunscreen lotions. Its alternating single and double bonds are similar to melanine, the natural sunblock pigment produced in skin. Melanine production is stimulated by the sun's ultraviolet rays to prevent sunburn. PABA, in high enough concentration can prevent UV rays from reaching the skin

PABA also shares chemical characteristics with the coatings used in sunglasses. Find out more in our blog PABA: UV Sunscreens

A molecular model of PABA in the Molymod Hybrid Dome style uses the atoms & bonds in the parts list below. Our free 3D Molecular Model Builder shows other styles & allows for image rotation as an assembly guide.
