This molecule is responsible for the aroma of coffee, which is due to the stimulant action of caffeine. The color of roasted beans (see left) is due largely to the reaction that occurs when organic substances containing nitrogen are warmed. Inside are seeds for a time the molecules responsible for taste and estimulante35 action.
b-KERATIN
Silk, the common name of the b-keratin, solidified fluid is excreted by a number of insects and spiders. The more valuable the silkworm, the caterpillar of the silk moth called. This fluid is a polypeptide made up largely of glycine, alanine and smaller amounts of other amino acids. The b-keratin molecules do not form a helix. Forman films – which are then stacked – where amino acid glycine is present in one side. This flat structure is perceived by touching the seda36.
These molecules, such as the aroma of vanilla or rose, reach receptors located in the vibrating hairs in the nasal region, called the epithelium. The interaction of molecules with the hairs in the brain is perceived as “smell.” So far identified seven types of receptors in the nasal cavity, which are located in an olfactory membrane of 2-3cm2. Each of these receptors corresponds to a basic odor. Similarly, there are four different types of chemical receptors in the front of our language. Correspond to the tastes salty, sweet, bitter and sour. The brain perceives as a chemical signal molecules reach the receptors in our sense organs.
It has been discovered how they are perceived and how they form the smell and taste, but so far scientists have not agreed on why certain substances have a stronger odor than others and why some tastes are pleasant and some not.
He thought for a minute. We could live in a world without smell, or taste. Since we would have no idea of these concepts, would not think having those perceptions. However, this is not what happens. A brown or brown soil with a characteristic odor, leaving hundreds of types of delicious fruits with different aromas, plants and flowers with hundreds of colors, shapes and fragrances. Why do these atoms come together on one side in an extraordinary way to give rise to matter, moreover, combine to produce tastes and odors? While all products of the earth with its many features we consider normal, are actually a blessing great and some of the great art of a Creator who made our stay more pleasant the world.
The above representation is in a malodorous molecule. The left to an aromatic molecule. As we see in these representations, what distinguishes the odor pleasant smell is the small difference in a microcosm invisible to the naked eye.
As for other living beings, some only eat grass and other various foodstuffs. Many of these foods are not good smell or taste. And although having not mean much for stocks that lack of awareness as we humans. Also we could feed one type of nutrient and other creatures. Have you thought about how life would have to eat one type of food and drink only water? Therefore, the taste and smell, like all other blessings, are precious attributes gives us God, the possessor of infinite grace and gifts. The absence of only one of these ways, our lives would be really sad. Man should always act in accordance with standards established by God to show you and our gratitude for all favors granted to us. In return for this attitude, promises us eternal life provided with unlimited blessings, much higher than those that we know on Earth. Here the act as “free sample” for which we have in the past. But what will be received due to a life of ingratitude, neglect and negligence towards him, not only what we rightly deserve:
And when your Lord proclaimed: “If ye are grateful, I will give you more (of My grace). But if ye show ingratitude, … Certainly, My punishment is severe” (Qur’an, 14:7).
How do you perceive the matter?
What we have said so far reveals that what we call matter is an entity with a color, smell, taste or specific shape as we thought. Imagine that “matter” is our body, the living room, our home, ie the world, the universe. But in reality it is all energy. So why do we see and touch around us?
The reason those things we perceive as matter is the collision of photons with electrons in the orbitals of the atoms and the attraction and repulsion of atoms together.
You are not touching the book you now think you have in your hands … In fact, his hands repelling atoms to atoms of the book and the sense of “play” depends on the intensity of this repulsion. As mentioned when discussing the structure of atoms, they can approach each other at most a distance equal to the diameter of the same. Moreover, the only approach that can reach both are reacting with each other. Therefore, when even the atoms of the same substance may come into contact, is just impossible for us to touch, tight or lift up our hands a substance other than us. If we could get so close to the object in our hands, we would form part of a chemical reaction with the same, which would make it impossible for us or anyone else living in our place will survive for even a second, while we would transform into something else.
The final picture that emerges from this situation is extremely interesting: we live in a world made up 99.95% in an area full of atoms that consist almost entirely of energía37. I never really play what we believe “play or hold.” So to what extent perceive the matter we see, hear or smell? Or rather, do we see, hear or smell really such substances? For nothing. We had dealt with this when we speak of electrons and molecules. Remember it is literally impossible for us to see the stuff that we think exists, because the phenomenon we call “vision” includes some images that form in our brain by photons from the sun or other source of light hitting the matter. This absorbs some of that light and emit or reflect the rest, which is what reaches our eyes. Consequently, how many of the data pertaining to the matter to our attention by means of that information? Do not possess any evidence that the original forms of matter that exists outside the country are reflected to us completely.
