phenylthiocarbamide การใช้
- In 1931 Arthur Fox in Wilmington, Delaware, synthesized phenylthiocarbamide ( PTC ).
- Differential ability to taste the bitter compound phenylthiocarbamide ( PTC ) was discovered more than 80 years ago.
- There is an inverse correlation between the ability to taste phenylthiocarbamide and bitterness in " A . bunius ".
- The mechanism of transduction is shown by exposure of the endocrine and gastrointestinal cells containing the receptors to bitter compounds, most famously phenylthiocarbamide ( PTC ).
- In 1931, Arthur L . Fox, a DuPont chemist, discovered that some persons found phenylthiocarbamide ( PTC ) to be bitter while others found it tasteless.
- People who can taste phenylthiocarbamide ( PTC ), which is either bitter or tasteless, are less likely to eat cruciferous vegetables, due to the resemblance between isothiocyanates and PTC.
- Evidence supports a genetic link between the Kell blood group ( on chromosome 7 q33 ) and the ability to taste phenylthiocarbamide, or PTC, a bitter-tasting thiourea compound.
- The study of human taste genetics got under way in 1931 when Dr . Arthur L . Fox, a chemist at the Du Pont Co ., synthesized a chemical called phenylthiocarbamide.
- Perhaps his most remembered work is his study of phenylthiocarbamide, a chemical that tastes bitter to some individuals but is without taste to others, depending on the inheritance of a single gene.
- Researchers began suspecting as much in the 1930s, after a chemist who was making a batch of a compound called phenylthiocarbamide ( PTC ) let a puff of the crystals fly into the air.
- A dislike for cabbage or broccoli can result from the fact that these plants contain a compound similar to phenylthiocarbamide ( PTC ), which is bitter or tasteless to some people, depending on their taste buds.
- However, some cats have been known to be tempted by them it may not be as effective a deterrent for cats as it is for humans, or perhaps some cats are not deterred due to a genetic factor similar to that affecting human perceptions of the taste of phenylthiocarbamide.
- There's also a number of genetically-related taste differences know, including sensitivity to phenylthiocarbamide ( incredibly bitter or tasteless, depending on genetics-PTC overlaps somewhat with supertasting in ways that aren't entirely clear ), sensitivity to talk ) 17 : 25, 23 June 2014 ( UTC)
- While the extent of the taste differential among humans has been uncovered only recently, scientists have known of genetic taste differences since 1931, when a researcher, A . L . Fox, found that some people taste a chemical called phenylthiocarbamide ( or its synthetic equivalent, known as PROP ) as bitter but others say it has no taste at all.
