Difference Between L-Leucine and Isoleucine

Isoleucine manufactured only by plants and certain microorganisms, a process that relates to the conversion of pyruvic acid, and relates to the identity of the α-ketoglutarate. Pyruvate is a natural part of the substance of carbohydrate and fat metabolism, and α-ketoglutarate is another metabolic compounds. Promote the aerobic respiration of the cells. Leucine, and also by the synthesis of microorganisms and plants and involving pyruvate metabolism, different intermediary substance, i.e., the involvement of α-keto-isovalerate.
Leucine and isoleucine are two different amino acids, and dietary protein in humans eat food main ingredient is a naturally occurring substance. Both are considered essential amino acids, which means that the body can not produce these compounds in their own, and therefore they must be consumed in food. In addition, both leucine, isoleucine, are readily available protein-rich plant and animal foods, such as walnuts, almonds, soy, eggs, meat, milk and supplementary form very popular. Is important to note that both have a different chemical formula, the compound from a different source, the role of the different enzymes to be synthesized, and have slightly different functions in vivo.
Leucine, isoleucine, also vary, in order to facilitate its required for synthesis of the enzyme in plants. Want to create a chemical reaction from pyruvate, four enzymes or substances Quick Start, iso-leucine is required: acetolactate synthase, acetohydroxyacid reductoisomerase, dihydroxy acid dehydratase and valine transaminase. Contrast, the leucine synthesis requires three addition to the α-isopropyl-synthesizing enzyme, α-isopropylmalate isomerase, and leucine amino transferase.
These two amino acids is also performed once consumed slightly different functions in the human body. With the amino acid valine, leucine and isoleucine as branched-chain amino acids (branched chain amino acid) is known, which means that they have an extra carbon-based side chain in its molecular structure. Branched-chain amino acids and tissue growth and repair, as a supplement to make them popular bodybuilders and weightlifting. In addition, whether the body is stored in the liver, muscle, and stored in the body fat. However, only leucine, has been shown to encourage the manufacture of a protein in muscle cells, which is necessary for muscle hypertrophy, or growth.
L-Leucine synthesis of a large number of plant foods, including soybeans, peanuts, wheat germ, almonds. Intensive plants, isoleucine foods, including soybeans, seaweed. Animal breeding food tend to consume a large number of amino acids containing plant foods, including corn, wheat and soybeans. Similarly, aquaculture feeding kelp. For this reason, a large number of leucine, isoleucine transfer to eat animal food, including eggs, poultry, beef, lamb, fish.
