Amino Acids
Saturday, July 10th, 2010Amino Acids
How are amino acids excreted from the body?
I’m aware that proteins can be deaminated, producing a hydrocarbon and a nitrogenous molecule which is excreted through urine. Are there other ways? Is it common practice for kidneys to just excrete excess amino acids?
No. The nitrogen is converted to urea through the ornithine metabolic cycle. Urea is the only nitrogen compound excreted in the urine.
When the kidneys are failing, protein gets through into the urine: proteinuria.
When amino acids are incompletely metabolized, as in the inborn error of metabolism phenylketonuria, phenylalanine is deaminated to phenylpyruvic acid, which cannot be metabolized further, and so spills into the urine. Unless detected and treated, the result is severe mental and physical retardation.
Perhaps you have noted on the label of a can of diet soda sweetened with aspartame, “Phenylketonurics: Contains phenylalanine.”

The Importance of Amino Acids
There are few very basic materials required to sustain life, and while some people might think that food and water are adequate, the real answer is the “right” food plus plenty of water.
The right foods mean those capable of supplying the body with adequate nutrition and the materials that are necessary to all bodily functions. One of the most crucial of the materials required for good health are amino acids. These come strictly from protein rich food sources, including meats and fish as well as dairy products and some vegetables and grains. They are responsible for the production of the body’s 15,000-plus enzymes and they play a significant role in everything from digestion and sleep to mood and overall health. Their primary and most important role, however, is in the digestive process and anyone looking to maintain good nutrition and absorption must pay attention to their amino acids consumption as well.
There are many supplements for those hoping to increase the amino acids in their bodies, but a few considerations must be taken into account before making a purchase. First, many amino acids supplements are dairy based, so anyone with sensitivities or allergies to dairy products should check all of the ingredients before consuming them.
Additionally, many people use amino acids to help them process protein shakes and body building supplements in a more effective manner. Interestingly, some studies have shown that amino acid supplements are processed in a more thorough fashion when consumed simultaneously with carbohydrates, and this is the reason that some amino acids supplements are available as shakes and bars as well as powders and pills.
While carbohydrates can help an athlete to get all of the energy boost they want from their amino acids supplements, anyone who is using amino acids to improve their nutritional level must consider a few key issues. First that there are two common vitamins necessary for the body to absorb amino acids and these are vitamins B6 and C, and so when purchasing supplements it might be wise to look for one that provides the desired amount of amino acids, but is also accompanied by these two essential vitamins. It is also a good idea to understand the difference between essential and non essential amino acids, and only use those supplements that contain all of the amino acids as this is the only way to prevent any kind of deficiency.

How do vegetarians get enough amino acids to build muscle?
I’m trying to make sure that i get enough amino acids to build muscle after i work out, but i don’t know which vegetarian foods have enough amino acids to do this. Any insights?
they eat nuts. it doesn’t work on most people because i know a girl who was vegetarian but later turned vegan and from the lack of vitamins, she now has a blood disorder. she sings good, though.
