Chemistry and Love

it may seem unromantic to talk about chemicals when addressing topics such as romantic love, but it was shown that each stage of love is marked by the production of substances specific chemical in the body. The discovery of "chemistry of love" was the result of a study conducted by a team of Italian researchers led by Dr. Enzo Emanuele at the University of Pavia. According to the authors of the research there is a real "love molecule" called NGF (Nerve Growth Factor = nerve growth factor). This molecule was examined about 60 couples, men and women aged between 18 and 31 years who had recently fallen in love and were together for less than six months. Among those selected were the lovers who claimed to be truly and deeply and spent at least four hours a day thinking about their partner. You found that both men and women showed high levels of NGF, 227 units compared to 123 units recorded in pairs or single long course. It was also found that those who reported feeling more intense had higher levels of NGF. The bad news is that "it does not last for ever": the same study has shown that by analyzing the same people involved after one year in the same report, the NGF was reduced to the same levels of those engaged in stable relationships and single . Anthropological studies, moreover, in which examined the activation of certain brain areas in males and females, have a functional confirmation of certain preferences regarding the sex: men like to watch, women fantasize. Males are more rapid fall in love, women more slowly in men The thought of a loved one active brain areas linked to vision and the erection, in women, but the areas affected by the memories. Reviewing the various phases of love, moreover, we can even identify "three types of love." During the evolution of the human brain has developed three systems to allow for reproduction: the first is related to sexual attraction, which drives individuals to mate, we can define this as the first stage of falling or being the "availability" . The substance involved in this process of abandonment and preparation all'amore è l'adrenalina, prodotta dalle ghiandole surrenali quando l'organismo è sotto stress. Essa provoca aumento della pressione arteriosa, dilatazione di bronchi e pupille, arresto della digestione, tutte condizioni interpretate dal partner come messaggi di seduzione. Una dimostrazione ci viene fornita da un antropologo americano che ha condotto i) seguente esperimento: ha mostrato a diverse persone due foto della stessa donna, presentandole come gemelle e ha chiesto quale delle due fosse più desiderabile. La stragrande maggioranza degli intervistati ha scelto quella in cui la donna aveva le pupille dilatate artificialmente. L'amore fa strani effetti... improvvisamente una persona assume un significato particolare nella vita di un altro, nasce un amore romantico, ma quelle intense sensazioni provate sono in realtà da legare alla produzione di dopamina (neurotrasmettitore); si inizia a non dormire, a perdere peso, a pensare continuamente all'altro e questa situazione quasi "ossessiva" è favorita dai bassi livelli di serotonina. ancora una volta una molecola prodotta dal nostro corpo.La seconda fase dell'innamoramento è quella della passione. La sostanza coinvolta questa volta è la feniletilamina (PEA), che è simile all'anfetamina; produce un vero e proprio senso di esaltazione ed aumenta le prestazioni psicofisiche. Provoca assuefazione e se viene a mancare, scatena una depressione da astinenza. Chi passa da un flirt all'altro, non appena si attenua la fase di infatuazione, can be defined as a true addict of Attraction. " The action of PEA affects young people more than adults. A curiosity is that traces of PEA can be found in the water of roses and chocolate, maybe that explains why you give roses during courtship and eat chocolates when it ends a love! The third stage of love is attachment or long-term consolidation. The hormone that stimulates the affection is mutual attachment lossitocina, produced by the pituitary. In an American university has found that giving oxytocin to male mice helped them build the nest and protect the offspring, if you block the production of this hormone, however, devour their children. Another key substance involved in this phase is vasopressin, whose production is greatly increased in women causing a feeling of total contentment. Can play an important role in the birth of a new love even the "casual sex". It may in fact trigger romantic love. Sometimes you make love to anyone who is just a friend and suddenly find yourself madly in love: The high level of testosterone caused sexual excitement may induce high production of dopamine in the brain and trigger love. We can also distinguish a further stage of love, that of maturity. At this stage, the couple continues to be linked through production of endorphins. some proteins produced by the brain that have an analgesic and sedative. To stimulate this production is the constant presence of the partner. Perhaps someone may seem irreverent to study the chemistry of love ", perhaps because love can be considered too frivolous, too personal or too sacred to be subject of study? But love can enjoy, it dies and you can get sick ... Understanding the basics of love will not remove it its charm, as well as knowing the biochemistry nutrition does not alter the taste of good food. Whoever believes in the eternal love continues to do well, after all not forget that man is the only animal that can afford to do or try something for the sheer pleasure of it!

ESTRADIOL, the female hormone

I did a nice test on facebook and the result is this:
interesting .....

Estradiol is the estrogen No. 1 issued by the ovaries throughout the reproductive life of women. It gives shape to their curves and makes the hair silky. It also acts on the brain, where it promotes promiscuous tendencies in the fertile days of ovulation. Uuh! My girl, you the picture of what attracts men and women: an hourglass body, sinuous movements ... and a little 'flirtatious. If you are a man, well ... sure women have a crucial role in your life!

elixir for prolonging the life of a 30% resides in the potential of an isotope of hydrogen (deuterium symbol D), the energy of a chemical bond is equal to the energy needed to break down, this value depends on the atoms connected to the same link (in our case is interesting to evaluate the CH bonds and CDs) strength increases if the atoms are linked to an atomic mass greater (ie, isotopes are present).
In our organization a lot of damage occurs from the oxidation or radical attack of molecules at the level of CH bonds, a scientist has published a study (tested on other organisms) the actual increase in life expectancy in the presence of a number CD plenty of links that would be more resistant to such attacks. Two atoms are called isotopes of the same atomic number (number of protons) but different atomic mass (they differ in the number of neutrons).
The deuterium could be introduced in our metabolism through food appropriately modified.
Among the many ideas unpacked a few more years to live this seems the only one who can count on a real chemistry, the problem will be transferred to humans this hypothesis.

The chemistry of love

Hello guys my mind is already committed to arrange everything for S. Valentino .... nn the other day that the love and passion for the beloved devono mancare anzi... ma a S. Valentino tutto deve essere davvero speciale ecco come usare la Chimica la nostra arma vincente della vita.
S. Valentino e la chimica dell'amore
L’amore vero è una questione di chimica. La Lei ed il Lui si decidono anche in base a odori e feromoni, segnali che non percepiamo coscientemente in quella che può definirsi la neurochimica dell’attrazione. Non solo forme fisiche, e mente pronta. Ci sono anche meccanismi sottili e sconosciuti che governano i sentimenti, l’amore e l’attrazione. Per innamorarsi è necessario un cocktail di differenti segnali neurochimici, mischiati a stimoli esterni, che devono arrivare al momento giusto per accendere l’amore. Elemento fondamentale della chimica dell’innamoramento è l’odore. Ciascuno di noi è più sensibile a determinate fragranze, scelte non solo in base alle preferenze istintive, ma anche al condizionamento culturale. L’odore costituisce la cornice che delinea gli standard di attrazione di una certa persona. Agli odori fiutati si uniscono poi i feromoni, segnali misteriosi per l’uomo, che arrivano inconsciamente al cervello attraverso il naso. Comandano l’attrazione sessuale, come pure la paura, l’aggressività, il senso di territorialità più evidente tra gli animali. I feromoni sovrintendono soprattutto alla scelta del partner sessuale. Poi, l’udito, il tatto e la vista completano il quadro e scelgono per noi l’anima gemella. Ma è l’odore il vero cupido. Tanto che ci sono uomini e donne che sono in grado di riconoscere la maglia del partner a occhi chiusi. A completare il quadro interviene il cervello, che produce le sue sostanze capaci di legarci a lui o lei. Si chiamano vasopressina e oxitocina i due peptidi coinvolti nelle relazioni affettive a lungo termine. Mentre il neurotrasmettitore chiamato dopamina ci rende piacevoli l’amore e il sesso. Quale posto rimane allora a cibo e afrodisiaci vari, nel processo di innamoramento? Sono un mito, senza alcun fondamento reale. Meglio sarebbe per San Valentino pensare a un buon odore piuttosto che al look giusto. Miglioreremo le probabilità di successo. Fonte: Adnkronos Salute

The secret of a good steak (but not only) is called the Maillard

The most important chemical reaction of the whole kitchen is definitely the Maillard reaction. If you cook a food that is "darkens" almost always is the work of this reaction, which occurs at high temperatures between 140 ° C and 180 ° C, between amino acids of proteins and sugars. You can see it in action when the chips fry, bake as bread, cake, or a nice steak.

Bis (2-methyl-3-furil) disulfide

One molecule in particular is associated with taste roasted meat, and is the bis (2-methyl-3-furil)-disulfide. I guess not surprised to learn that there is a substance used in the food industry to create the flavor of meat. " There is obviously nothing wrong with that

But the Maillard reactions that occur by cooking a piece of meat produce hundreds of different molecules, which provide a taste and flavor much more complex than it can provide a single molecule.
