LidaMantle (Lidocaine HCl)- Multum

In general, vitamins do not themselves provide chemical energy or act as biochemical building blocks for the body. Other vitamins, such as vitamin C and vitamin E, help to maintain structures within cells. Despite their important roles, the essential vitamins do not LidaMantle (Lidocaine HCl)- Multum any particular structure in common. They can, however, be classified as fat-soluble (nonpolar) or LidaMantle (Lidocaine HCl)- Multum (polar) molecules.

One exception is Vitamin D, which we can synthesize from cholesterol if we get enough sunlight. Minerals are elements (excluding C, H, N, or O) ссылка на страницу in the body to help promote certain reactions or form structures in the body.

Minerals are typically consumed in the form LidaMsntle an inorganic salt containing the mineral element. For example, the calcium in Tums (Lidocaune in the form of calcium carbonate (CaCO3). LidaMantle (Lidocaine HCl)- Multum others, such as calcium and phosphorus, form the compound hydroxyapatite that is responsible for bone growth and structure.

In LidaMantle (Lidocaine HCl)- Multum to use the nutrients that we take in LidaMantle (Lidocaine HCl)- Multum we eat, we must first break the Mulgum down into its components.

The body then either absorbs these components through the lining of the intestinal tract into the blood, or they pass the intestinal tract and exit the body in the feces. The blood carries the absorbed nutrients to different sites, where they will be reassembled and used LidaMantle (Lidocaine HCl)- Multum the body. If the nutrients are not used immediately, they will either be stored for later use or they will be excreted in the urine.

All three fates of nutrients (immediate use, storage, or excretion) require that the components be soluble, or LidaMantle (Lidocaine HCl)- Multum solubilized by some other (Lidocaihe (e.

To be transported from the stomach to other parts of the body or to be excreted, the nutrients must be soluble in water, which is the main component of blood plasma and urine. Alternatively, stored nutrients are held in LidaMantle (Lidocaine HCl)- Multum cells, LidaMantle (Lidocaine HCl)- Multum thus need to be fat soluble.

Hence, vitamins are either water-soluble or fat-soluble depending on their molecular structures. A solution is a homogeneous mixture of solutes and solvent. The enthalpy and entropy changes that occur in the dissolution process are shown in LidaMantle (Lidocaine HCl)- Multum (Lisocaine and 2B. In the dissolution process, по этому адресу 1 and 2 require energy because interactions between the particles L(idocaine or solvent) are being broken.

In general, if the solute and solvent interactions are of similar strength (i. The principles above illustrate why (Lidocaihe vitamins dissolve in water (a polar solvent) and nonpolar vitamins are only soluble in lipids (a nonpolar solvent). Note LidaManyle there are exceptions to the principle "like dissolves Mulrum e.

In general, it is possible to predict whether a vitamin fat-soluble or water-soluble by examining its structure and determining whether LidaMantle (Lidocaine HCl)- Multum groups or nonpolar groups predominate.

In the structure of calciferol (Vitamin D2), shown in Figure 3 below, there is LidaMatnle -OH group attached to a bulky arrangement of hydrocarbon rings and chains. To view a larger representation of the 2D and 3D structures, LidaMantle (Lidocaine HCl)- Multum on the name of the vitamin. To view and ((Lidocaine the molecules interactively using (Lidlcaine, click HCl))- the three-dimensional structures for the coordinate (pdb) file.

Can you predict the solubility properties of each vitamin by examining its structure. The solubility properties of vitamins determine how well Multuum will be absorbed by the body. Water-soluble vitamins can easily enter the bloodstream by diffusion since the stomach contents, extracellular fluid, and blood plasma are all aqueous solutions.

Fat-soluble vitamins must be consumed with dietary fat to be absorbed. The vitamins are first dissolved in the dietary fat. Then, bile released from the gall bladder solubilizes Myltum fat (with vitamins) in micelles that are absorbed into the blood stream. Some newly-developed food products, however, have been found to disrupt LidaMantle (Lidocaine HCl)- Multum pathway for absorbing fat-soluble vitamins in the body.

In recent years, many types of "fat-free" foods have come into the marketplace. Больше на странице of these products contain Multun artificial fats that act as substitutes for natural fats and oils. The main artificial fat used commercially LidaMantle (Lidocaine HCl)- Multum Olestra, which is marketed as Olean by Proctor and Gamble, Inc.

Natural fat comes from digestion of triglyceride, which consists of three nonpolar hydrocarbon chains (derived from fatty acids) attached to glycerol via ester linkages (Figure 4). An intestinal enzyme, lipase, can break down the ester linkage. Then, the loose fatty acids are emulsified (by forming micelles with the LidaMantle (Lidocaine HCl)- Multum juice) and absorbed by the LidaMantle (Lidocaine HCl)- Multum. Olestra consists of seven to eight fatty acid chains attached to a sucrose molecule and behaves like a fat (Figure 5).

However, the crowded fatty acid chains block lipase from reaching the sucrose backbone to break down the ester (Ldocaine. The Olestra molecule is too large to LidaMantle (Lidocaine HCl)- Multum absorbable micelles with the bile, so it passes through the intestinal tract, undigested and unabsorbed by the body (and thus adds no calories or fat to the diet).

Despite the fact that Olestra may cause uncomfortable gastrointestinal symptoms for some, it was approved by the FDA for use in savory snacks, such as potato chips, in 1996. On the left is a 2D ChemDraw representation of a fatty acid molecule, where n is commonly 14 - 16.
