Why do growing pigs have a dietary requirment for specific amino acids?
148164
amino acids is in other words, proteins..\ngrowing pigs need these proteins so that new cells are made and thus so that they can develop and grow..proteins are also used to make hormones that are necessary for the body to function properly..proteins also help in the making of enzymes that help to break down join up certain substances within the pig's body..there r many more functions of proteins but the basic one is to promote growth..\nThis is the reason why pregnant ladies are adviced to take lots of protein in their diet..so that the unborn baby can grow and develop..

Water and "nutrients" depending on the specific type of cell. Plant cells need inorganic nitrogen compounds (ammonia, nitrate), phosphate, iron, magnesium, manganese, copper,...\nAnimal cells need organic substances like sugars or amino acids (which plant cells can produce on their own) additionally to vitamins and ions (iron, copper, cobalt, zinc, molybdenum, iodine, selenium,...)

They do have taste buds and have a definite preference of one type of food over another.  Also, animals have an excellent sense of smell and that is an important component of how food tastes and determining if one thing is better to eat than another.

“Glutamine is found in many foods high in protein, such as fish, meat, beans, and dairy products.”\n\nhttp://www.vitacost.com/science/hn/Supp/Glutamine.htm\n\n“… naturally occurring glutamate is labeled as L-Glutamine … \n\nGlutamate itself is in many living things: it is found naturally in our bodies and in protein-containing foods, such as cheese, milk, meat, peas, and mushrooms. Some glutamate is in foods in a "free" form. It is only in this free form that glutamate can enhance a food's flavour. Part of the flavour-enhancing effect of tomatoes, certain cheeses, and fermented or hydrolyzed protein products (such as soy sauce) is due to the presence of free glutamate”\n\nhttp://en.wikipedia.org/wiki/Monosodium_glutamate\n\n“5-HTP is not present in significant amounts in a typical diet. The human body manufactures 5-HTP from L-tryptophan, a natural amino acid found in most dietary proteins. However, eating food that contains L-tryptophan does not significantly increase 5-HTP levels. Supplemental 5-HTP is naturally derived from the seeds of Griffonia simplicifolia, a West African medicinal plant.”\n\nhttp://www.truestarhealth.com/Notes/2793000.html

As Christianity infected the world, it entered areas where pork had always been consumed, this continued. No source of protein that delicious would go un-utilized by hungry people who had a tradition of consuming it.

Because cells must keep an optimal surface area:volume ratio in order to be able to receive food and transport it throughout the cell effeciently. If they grew too large, they would starve and die.

essential amino acids are organic compounds not synthesized in the that is essential for nitrogen equilibrium in adults and optimal growth in infants a children  Adults require isoleucine, leucine, lysine, methionine,phenylalanine, threonine, trytophan and valine.  Infants need these eight amino acids plus arginine and hisstidine.  Cystine and tyrosine, limited substitutes for methionine and phenylaalanine, are considered quasi-essential.  Does this help answer your question?  That's all I have.

It would take all 20 amino acids, arranged in some specific order. The amino acids are the minor part, because bone is not made of protein. Bone defines the face more so than the muscles on top.

No, I don't really think so. Everything you said is basically true, but digestion occurs and in digestion your body will only take in which specific amino acids it needs at that point in time (we have no real way to store amino acids) and excete everything else.  So if you eat a lot of tryptophan your body will just stop taking it in when it doesn't need any more. \nAlso, your body can switch a lot of amino acids into a different amino acid. So if you have a lot of one and need more of another, your body can just make that one.\nNote that there are some "essential" amino acids, meaning that your body cannot make them and they must be ingested!\nAlso, maybe there's a bit of confusion on the codon thing. A codon is a specific sequence in the mRNA of 3 nucleotides that codes for an amino acid. A tRNA with the complementary anticodon will bring this amino acid to the growing chain. Only the tRNA that matches the codon will come in. This cannot be influenced by what you eat.

The amino acids that go into making proteins are so-called alpha-amino acids. This is because they have an amino group (-NH2) on the carbon atom just next to the carboxyl group (-COOH). The simplest such amino acid is glycine, H2N-CH2-COOH. Another simple one is alanine, CH3-CH(-NH2)-COOH (three carbons, the NH2 group on the second one). There are about 22 amino acids that go into the making of proteins. Some are essential: This means that the body cannot make them, and they are needed in the diet. Others are nonessential: The body can make glycine and alanine from other raw materials.

the body takes all the proteins that you eat apart and turns them into amino acids, and then the amino acids infiltrate into the places where they're needed...!

I believe your friend.\nChicken & several other domestic animals are routinely fed hormones, steroids are made from hormones\nAlso other Growth builders, that we don't know about.  Including Human Sewage, in some places .\nIf I were you I'd give up eating animals, if you want to cut-out dangerous chemicals!

l-glutamine is an amino acid. the human body 'builds' l-glutamine. it is made of valine and isloleucine. you can buy l-glutamine as a food supplement when doing a lot of sports. it is used during itense training excercises (you do not have to additionally take it when not lifting weights like crazy,...)\n\ngood luck

Lysine is formed by microorganisms acting on carbohydrates. There are quite a few such microorganisms. Each of these organisms requires special conditions and/or special additives to produce the product in good yield.

There are two kinds of amino acids - essential and nonessential.\nHuman bodies require twenty amino acids to function properly. Nine essential amino acids cannot be manufactured by a human body and you need to get them from food. Eleven nonessential amino acids can also be obtained from food, but our body can synthesize them as needed on its own.\n\nIt used to be popular to supplement with aminos especially in the bodybuilding circles, but as more research became available, the consensus seems to be that in majority of the cases supplementation is not necessary. There are some cases when a trained athlete may benefit from it, but your money will be much better spend on quality food.

There are several areas to check, including:  many websites about the animals themselves or a college website pertaining to physiology.  For the animals, you might want to try a website of an animal food company.

amino acids are always needed for energy, long-term energy:\nanimo acids are the building blocks of protein, and when consumed and digested provide long-lasting energy, well, in relation to sugar and other carbs which only provide a quick burst of energy. Protein just generated an overall larger amount of energy upon consumption than anything else. \nit depends in what form u are using "amino acids"...\nif u are just eating lots of meat, beans, whatever protein that its OK, but if u are taking supplements u should consider not doing that b/c all the protein powders and such are not too good for yur liver and they make u gain too much weight, unless u r a hardcore weight lifter. \nso in short: dependng on how much and how quick of energy u r looking for would tell u whether u should eat protein or carbs. but protein supplement should ONLY be taken if u r working out (but preferably not at all).\nhope this helps.
