Pesticide molecule

Malathion. Computer model of a molecule of the organophosphate pesticide malathion. It has the formula C10.H19.O6.P.S2. The atoms are shown as spheres and are colour- coded: carbon (blue), hydrogen (white), oxygen (red), phosphorus (green) and sulphur (yellow). Malathion is a wide- spectrum pesticide used to protect crops from sucking and chewing insects and to treat lice on humans. It belongs to a class of chemicals called cholinesterase inhibitors, which kill by blocking the enzyme acetylcholinesterase, causing paralysis. Large doses of malathion are toxic to humans and can be fatal

EDITORS COMMENTS
This print showcases a computer-generated model of the pesticide molecule, Malathion. The intricate structure is composed of spheres representing different atoms, each color-coded to denote its element. Carbon appears in a striking blue hue, hydrogen in pristine white, oxygen in vibrant red, phosphorus in lush green, and sulphur shines brightly in yellow. Malathion serves as a potent wide-spectrum pesticide that safeguards crops against both sucking and chewing insects while also combating lice infestations on humans. Classified as a cholinesterase inhibitor, this chemical compound acts by obstructing the acetylcholinesterase enzyme responsible for transmitting nerve impulses. This paralysis-inducing mechanism ultimately leads to the demise of targeted pests. However, it is crucial to note that excessive doses of malathion can pose severe risks to human health and even prove fatal. Hence, caution must be exercised when handling this toxic substance. The mesmerizing illustration depicted here not only highlights the structural complexity of malathion but also underscores its potential dangers. Through this visually stunning artwork created using advanced computer technology, Science Photo Library presents an opportunity for viewers to appreciate the intricate world of chemistry and gain insight into the molecular realm that underpins our understanding of pesticides and their effects on living organisms.
