Title : Food toxicity
Abstract:
Chemistry is an essential part of our day-to-day life. We find chemistry in daily life in food we eat. Food is a mixture of hundreds of Chemicals anyone of which in excess quantity would be harmful & may responsible for toxicity in body.However human beings cannot live without Vitamin A, Vitamins like Ascorbic acid,Carotinoids,tocopherols etc & trace elements like, Zinc, Copper,Methionine,an amino acid(a building block) &.It is wrong notion about food that,food should be free from Chemicals.Most of the food components are supposed to be Generally Recognized as Safe(GRAS).
Chemistry occupies an intermediate position between physics & biology. It is sometimes called,central science because it provides a foundation for understanding both basic & applied scientific disciplines at a fundamental level.eg. chemistry explains aspects of plant chemistry (botany), formation of igneous rocks (geology), how atmospheric ozone is formed & how environmental pollutants are degraded (ecology), the properties of the soil on the moon (cosmochemistry), how medications work (pharmacology) & how to collect DNA evidence at crime scene (forensics).
Importance of Chemistry: Everybody to understand basic chemistry including students because all sciences involve matter and interactions between types of matter.
It is important to distinguish between Toxicity & actual Hazzard. A particular food chemical may or may not be hazardous depending upon the many factors, specifically quantity consumed by a person. This knowledge was used to control undesirable microbes & effectively use the desirable types.Here,mejor role of Chemistry in Toxicity started.
Toxaemia- Presence of poisonous substances in blood. Almost all heavy metals are serious toxicants as carcinogens. Copper (Cu) & zinc (Zn), serve as enzymes that are essential for intracellular processes & have DNA-binding domains, almost all heavy metals induce various cancers & diseases. . Dissolved forms of toxic heavy metals can be magnified via circulation in bio-system, including food chain & finally end up in very high concentrations in humans.
