New discovery of the mystery of scent in each person

Scientists have found a solution for someone who smells this aroma very fragrant but others think that smell is horrible.

Few people know that, not all of us can smell the same scent. There are some people who smell this aroma very fragrant but others think that smell is terrible. The solution of this problem has been found by American scientists. Accordingly, there is a slight difference of DNA - an amino acid on the body's genes, that not everyone can smell the same smell.

Researchers at Duke University, North Carolina discovered, there are nearly a million genetic variants on 400 olfactory cells in the human nose. These olfactory cells determine the smell and smell that will activate a part of the olfactory cell similar in the nose and signal it to the brain.

"These cells work differently in each person. Depending on the genome, many people like this smell, but others don't," said Hiroaki Matsunami, a professor of molecular and microbiology . I like it ".

To determine how the olfactory cell works and why people smell a different odor, his group has left 20 people sensitive to 1 - 2 types of amino acids smelling 73 different aromas at Very small concentrations such as vanillin and guaiacol (an aromatic substance derived from wood oils). Thereby, he identified 27 olfactory cells that reacted significantly to at least one odor.

Dr. Matsunami said that this study could have a big impact on the perfume industry and the food industry. Because manufacturers want to find new scents that many people care about, however, this is very difficult because each person feels different smells.
