Some people love to caffeinated beverages like coffee, but some did not like it. Telisik have telisik, it turns out people are fond of caffeine were due to hereditary factors, aka genes.
The result of research by scientists showing a very happy caffeine or not at all visible from the DNA (Deoxyribo Nucleic Acid) that is nucleic acid that stores all information about genetics.
The study found people who have two specific genes of CYP1A2 and AHR, were more likely to consume caffeine.
Studies reported in the journal PLoS Genetics, have identified CYP1A2 gene previously associated with caffeine metabolism and genes involved in regulating AHR CYP1A2.
"We know that caffeine is an inherited component but for the first time we specifically know the major genes involved," said Dr. Neil Caporaso, head of genetic epidemiology branch at the National Cancer Institute, as quoted from ABCNews, on Friday (04/08/2011) .
Dr. Caporaso said this study managed to identify genetic patterns associated with eating and this discovery is very clear for two kinds of genes that makes sense.
In this study, researchers compared the caffeine intake of the participants and do a search on more than 300,000 genetic markers before finally finding the two genes.Because a single gene that regulate other genes, to find both of these genes requires a fantastic job.
"Caffeine is one of the most frequently consumed substances that people with psychoactive properties is important, just try to stop consuming coffee for two days and see its effect," says Caporaso.
The information obtained can help researchers in studying the physical effects that are influenced by caffeine, including exercise, sleep, anxiety and various other medical conditions. And learn why people have different reactions to caffeine.
