nerve transmission, blood clotting, cell respiration and the formation / maintenance of bones and teeth. Cations potassium (K are essential in the transmission of nerve impulses. Phosphates ( Play an important role in DNA and RNA, as well as the molecule of ATP (adenosine triphosphate) responsible for storing and transferring energy in cells. Vitamins are organic substances necessary for many activities of our body, having the function of "aid" to "accelerate" other biochemical reactions. However, the vitamins are not synthesized in our cells are obtained by means of food, or food supply (vitamin complexes) and drugs, both under medical supervision. ), que é essencial à respiração celular por estar envolvida no transporte de elétrons e atuar na oxidação de ácidos graxos no fígado; e vitamina A , com funções diversas no organismo humano, sendo uma delas a de atuar no mecanismo responsável pela visão. Lettuce also has some vitamins, among them vitamin B (thiamine - C OS), playing a crucial role in the transformation of food into energy and transport of ions across the plasma membrane of neurons and muscle cells , vitamin B (riboflavin - C which is essential for cellular respiration to be involved in electron transport and act on fatty acid oxidation in the liver, and vitamin A, with different functions in the human body , one of which is to act in the mechanism responsible for vision. Vitamin A is found in food in its active form, neither indeed can be synthesized in our body. On lettuce found in the form of pro-vitamin A, beta-carotene, a hydrocarbon which can be converted in the process of digestion, retinol for alcohol (C O), which undergoes oxidation process, resulting aldehyde retinal (C O) as cis-retinal by the phenomenon of isomerism. In photoreceptor cells that form the retina of the human eye, under the action of light, the substance cis-retinal to trans (FIGURE 1). This transformation causes a response in the nerve cells, which is conducted by the optic nerve as a boost to the vision center in the brain, which interprets and allows us to see objects in positions that really are. Figure 1 - Representation of the mechanism of isomerization of cis-retinal substance, under the action of light, turning into trans-retinal.

živaca mjenjač, zgrušavanje krvi, disanje stanica i formiranje / održavanje kostiju i zubi. Kationa kalija (K su bitni u prijenosu živčanih impulsa. fosfati ( ima važnu ulogu u DNA i RNA, kao i molekule ATP (adenozin trifosfat) odgovoran za pohranu i prijenos energije u stanicama. vitamini su organske tvari potrebnih u raznim aktivnostima naših tijela, imaju funkciju "pomoći" da "ubrzaju" druge biokemijske reakcije. Međutim, vitamini se ne sintetizira u našim stanicama dobivaju putem hrane ili hrane (vitamina kompleksa) i drogama, i pod liječničkim nadzorom. Zelena salata također ima neke vitamine, među njima i vitamin B (tiamin - C OS), igrati ključnu ulogu u pretvaranju hrane u energiju i transport iona preko plazma membrane neurona i mišićnih stanica , vitamina B (riboflavin - C ), koja je neophodna za staničnog disanja da se uključe u elektrona i djelovati na oksidaciju masnih kiselina u jetri, i vitamina A , s različitim funkcijama u ljudskom tijelu , od kojih je jedan djelovati u mehanizmu odgovorne za vid. Vitamin se nalazi u hrani u svom aktivnom obliku, ai ne može se sintetizirati u našem tijelu. Na salata naći u obliku pro-vitamina A, beta-karoten , ugljikovodika, koji se može pretvoriti u proces probave, od alkohola retinol O) i prolazi proces oksidacije, što je rezultiralo aldehid mrežnice (C O) u obliku cis -retinal , fenomen isomerism. U fotoreceptora stanica koje čine mrežnice ljudskog oka pod djelovanjem svjetla, tvar cis -retinal se pretvara u transretinal (SLIKA 1). Ova transformacija izaziva reakciju u živčane stanice, koje se provodi od strane vidnog živca kao poticaj viziji centar u mozgu, koja tumači i omogućuje nam da vidimo predmete u položajima koji stvarno jesu. Slika 1 - Zastupljenost mehanizam izomerizacije tvari cis-retinal, pod djelovanjem svjetla, pretvarajući ga u trans-retinal.
