What is the purpose of zinc in food? Isn't it a metal?

I take zinc supplements during cold season. Zinc is a mineral that greatly helps our immune system. And just so you know, "metals" are not always solid shiny silvery lumps. Zinc in the supplement pills is a powder. Iron is another nutrient your body needs, did you know that?

it's ridiculous. Zinc should always be cheap! it's ZInc! come on

Hello there,\n\nAnswer is zirconium.\n\nYou can take this to the bank.

In a way, yes. \n\nZinc, as a metal, is actually one of the components of a dry cell/battery, along with lead (and, well...batteries are global sources of energy...in one sense). This supports the fact itself that all metals are potential energy providers...^_^\n\nZinc, as a mineral, is also taken by the body as, again, one of the components on milk and vitamins (you noticed commercials saying milk and vitamins contain Zinc? ^_^). These minerals do help in providing the body with optimum energy. The bodies of the people contributing to the "globalness" of our planet made Zinc a contributing factor in global energy... ^_^\n\nSo, either a mineral or a metal, Zinc has a contribution to global energy. Thank you. ^_^

Zinc does interfere with iron absorption and vice versa because they use the same transport system

Obviously, an unreactive metal. Well, you can galvanise the zinc, or you can paint it (I'm serious).

all the information you need is in the handy periodic table.   First, think about the charges of the molecules....\n\n In the molecule CuSO4, copper has two electrons to give.  The SO4 molecule wants TWO more electrons to acheive noble gas configuration (a stable electron state).   This appears to be a match in heaven.  \n\nWell all is fine until Zinc comes along.  If you look at the periodic table, Zinc is just to the right of copper.  It too has 2 electrons to donate......but, it is more electronegative than copper. (remember, electronegativity  is the lowest in the bottom left corner of the table(Fr) and increases on  a diagonal path  with F being the most electronegarive.)  \n\nSince Zinc is more reactive than Copper,  a replacement reaction occurs.  Zinc bumps Copper off of the SO4 molucule.  Zinc can be whitiish to yellowish in solution.  As all the Zinc is coming off the rod, it bumps the copper off the SO4 and also disperses the colour of the copper.  If you had one drop of blue dye (the copper), but added a cup of milk. ( the Zinc)...... you would barely see the blue color.

Make you hungry and desperate fro something decent to eat!!!\n\nSeriously though, it is a meal replacement system.  It contains all the minerals, vitamins and essential elements you need to survive but puts them in a low calorie "shake" (or soup, or bar...).  All it does is reduce the calories you take in over the day.  Personally Id rather eat a sensible low cal diet of real food!

It probably contains zinc since it ends the way it does. This is something that should work: \nhttp://www.inhousepharmacy.com/mens-health/saw-palmetto.html

when supplementing with Zinc it is important to use not just Zinc by itself it's important to supplement with a little Copper because too much Zinc can deplete blood levels of Copper and vice versa. You should not use more than 4mg of Copper a day in total. Also with Zinc you must be mindful:DO NOT use more than 100 MG of Zinc because  this after 10 straight days will depress the Immune System. A good safe ammount for women is 15-30 mg a day with 1-2 mg of copper. For Men 30-50 mg a day with 2-4mg of copper. Why slightly more for Men because Zinc is a chief factor in Testosterone production.And in general 100 other enzymes in the bodies of male and female need Zinc. OptiZinc is the best form of Zinc to use.

zinc is oxidised by almost all acids with varying degrees of rate.\n\nA+

In simple terms it is function. A protein is a polypeptide, but it is a polypeptide that does something. It has a purpose.\n\nYou can of course also have polypeptides that are just junk. They don’t do anything. Chemically they belong to the same class as proteins but they lack a function.\n\nJazzSinger said  “A polypeptide is a protein in the making”. That isn’t true, In fact most polypeptides are exactly the opposite: they are proteins in the process of being destroyed.  Food is loaded with non-protein polypeptides, not because proteins are being made in food but because the cooking process destroys proteins.

zinc (Zn) sulfate (SO4) penta (5) hydrate (H2O)  so it would be zinc sulfate pentahydrate

If you're deficient in zinc, supplementing with it can help increase testosterone levels and reduce estrogen levels which could possibly help with sperm production.  If you're not deficient in zinc, though, I don't think taking more will do anything.

No, the zinc ion has a positive charge because it is transition metal (+2 charge) but the sulfide ion has a negative charge (-2 charge). If you wanted, there could be a compound of Zinc Sulfide, since zinc is a metal and sulfide is a nonmetal.

The previous answers explain what metals DO in the microwave, but not WHY.  \n\nIt is not necessarily bad that metal is in the microwave: the walls of the microwave are made of metal!  What is so special about metal?\n\nThe reason that metals are shiny is that they have free electrons in them.  The free electrons in metal are what make the metal electrically and thermally conductive; ceramics don't have free-electrons and so are not shiny- metallic in appearance (you can tell just by looking).\n\nIt turns out that the free electrons in the metal reflect photons (energy packets) of light for both visible and thermal (microwave) ranges.  Long electromagnetic waves (microwaves) also behave as photons; we don't call them photons of light because we can't see them, but microwave photons are in fact the same kind of photon, just of lower energy.  It is important to understand that all that is going on in the microwave is that the metal in the microwave is reflecting the microwaves (and not being absorbed).\n\nThe way that microwave heat is by coupling electromagentically to 'wiggle' atoms (certain atoms/molecules anyway; those that have a dipole moment) very fast, causing heating (not metals of course - the microwaves bounce off; and not materials without a dipole moment, which is why some ceramics and glasses don't heat up).  Water isn't even the most efficient coupling material at microwave frequencies; this is why sugar heats up so much faster. \n\nThe microwaves are reflected by the metal walls until they are absorbed, (usually by water-containing food), their energy being converted to heat. Should absorption not take place - if, for example, the oven is activated when empty, some energy will re-enter the waveguide and cause over-heating of the magnetron. Usually a safety switch turns the machine off when this happens. Note that the reflecting walls and the constant frequency of the microwaves set up standing waves in the chamber. This results in some areas being much more active than others and is the reason why food must be rotated through the varying field to cook evenly.  \n\nSo why does a metallic fork arc?  The resonance induces enough movement in the electrons in the metal to create an electric field charge sufficient to arc (even though it is a reflecting material, electrical currents are induced).  Note that the metal object won't arc if it is grounded to the walls, and it won't arc if it is insulated sufficiently (I have a metal 'roast rack' in my microwave).\n\nGenerally it is not a good idea to put metals in the microwave because you want the food to absorb the energy, the manufacturer of the microwave spent a lot of time designing the standing wave energy field to be uniform to do just that, and introducing metal distorts that field - its OK if you know what you're doing, not so good if you don't have a purpose in mind.

I take zinc products at the first sign of a cold...cold-eeze or the Target version.Also echinacea herbal tea (some people say goldenseal helps them too)  Also lots and lots of Vitamin C!
