The technology of syringes without needles is similar to printers ink-jet. Syringes without needles In a strong jet (spray) bead is applied to the skin. Due to the pressure, the microspheres pass through the pores of the skin capillaries and reach the bloodstream they release the drug throughout the body. This technology is already used in U.S. hospitals. Another system known as "drug delivery", ie, drug delivery system in the CNS (central nervous system) is being developed. This system allows the drugs to be applied as a simple eye drop, straight into the eye. The system relies on the use of drugs in capsules polymer microspheres (long molecules formed by the repetition of small molecules) and proteins. These microspheres release the medicine (drug) in daily doses for weeks or months. With the new findings, medical chemistry got a big boost and today is one of the most growing areas of research in chemistry. ACTIVITY Demonstrate by molecular models of the tetrahedral structure by carbon analysis (CHBrClF) and (CH Cl The compounds are analyzed or achiral? Use a flat mirror to explain. Consider the information: A solution of common sugar (sucrose) subjected to polarized light produces a shift to the right of the observer, a mixture of glucose and fructose polarized light deviates to the left of the observer, so as fructose, glucose can be obtained from sucrose (a mixture known as invert sugar). What kind of isomerism occurs in invert sugar? Explain. Discover what the benefit for the food industry to use invert sugar. Make also a survey on the labels of food products that you commonly use. Identify which products offer invert sugar in its composition and show the results in tables. You know the popular saying: "To know the age of the horse you look at the teeth." Can this also happen with humans? From the protein present in the dentin of the tooth enamel and external testing racemization (racemic isomer) some scientists say it is possible to determine the age of a person. Do a search on the theme: "teeth that reveal the age" and perform with the help of the teacher a debate with colleagues to show that you have researched. Develop a survey to identify whether the drugs you use are pure enantiomers or racemates. Disclose their search through posters, banners, charts or graphs as a warning so that people are aware of the advantages and disadvantages of using drugs racemate or pure enantiomers.

Tehnologija šprica bez igala je sličan pisača ink-jet. štrcaljke bez igle u jakim mlazom (sprej) mikrosferama se nanosi na kožu. Zbog pritiska, mikrosfere prolaze kroz pore na koži, kapilarama i doći u krvotok što su puštanje lijeka u cijelom tijelu. Ova tehnologija već se koristi u bolnicama Amerikanaca. Drugi sustav poznat kao "lijekova", odnosno lijekova isporuku sustava u CNS (središnji živčani sustav) razvija se. Ovaj sustav omogućuje lijekovi koji će se primjenjivati kao jednostavan oka kap, ravno u oči. Sustav se oslanja na uporabu lijekova u kapsulama polimera mikrokuglica (dugačke molekule formirana od ponavljanja malih molekula) i bjelančevina. Ovo izdanje mikrosferama medicina (lijek) u dnevnim dozama za nekoliko tjedana ili mjeseci. S novim nalazima, medicinske kemije dobio veliki poticaj, a danas je jedan od najvažnijih rastućih područja istraživanja u kemiji. AKTIVNOST Pokažite molekularnim modelima tetraedarske strukture ugljen analizu (CHBrClF) i (CH Cl Spojevi su analizirali ili achiral? Koristite stan ogledalo objasniti. razmotriti podatke: rješenje od zajedničkog šećera (saharoze) podvrgnut polariziranu svjetlost stvara pomak u desno od promatrača, mješavina glukoze i fruktoze polarizirano svjetlo odstupa s lijeve strane promatrača, kako fruktoze, glukoze može se dobiti od saharoze (mješavina poznat kao invertni šećer). Kakav isomerism javlja u invertni šećer? Objasnite. Otkrijte što se koristi za prehrambenu industriju koristiti invertni šećer. Provjerite je također istraživanje na etiketama prehrambenih proizvoda koji se obično koriste. Odredite koje proizvodi nude invertni šećer u svom sastavu i pokazati rezultate u tablicama. Znate popularnu izreku: ". Da znate u dobi od konja pogledate zube" Može li se to dogoditi i sa ljudima? Od proteina prisutnih u dentin u zubnu caklinu i vanjskog testiranja Racemizacija (racemične izomer) neki znanstvenici kažu da je moguće odrediti starost osobe. Učinite pretragu na temu: "zube koji otkrivaju dob" i obaviti uz pomoć nastavnika rasprave s kolegama pokazati da ste istraživao. Razviti anketu kako bi se utvrdilo da li su lijekovi koje koristite su čista enantiomera ili racemati. Objaviti potragu putem plakata, banneri, grafikone ili grafikone kao upozorenje, tako da su ljudi svjesni prednosti i nedostatke korištenja lijekova racemat ili čistih enantiomera.
