An essential amino acid,
adult male requirement (2.2g / d) (Japan). necessary for normal
growth of infants and for adults to maintain normal nitrogen
balance
Naturally exist in spleen and heart, in the form of the protein in
a variety of animal and plant tissues.
Applications:
Nutritional supplements;
flavoring agent.
Preparation of amino acid infusion
and comprehensive amino acid preparations, hypoglycemic agents and
plant growth promoters.
Leucine works with the amino
acids isoleucine and valine to repair muscles, regulate blood
sugar, and provide the body with energy. It also increases
production of growth hormones, and helps burn visceral fat, which
is located in the deepest layers of the body and the least
responsive to dieting and exercise.
Leucine, isoleucine, and valine are
branched-chain amino acids (BCAAs), and all three of them help
promote muscle recovery after exercise. Leucine is
the most effective BCAA for preventing muscle loss because it
breaks down and is converted to glucose more quickly than
isoleucine and valine. Increased glucose supplies prevent the body
cannibalization of muscle for energy during intense workouts, so it
is no surprise that this amino acid supplement is popular among
professional body builders. Leucine also promotes the healing of
bones, skin, and muscle tissue after traumatic injury, and is often
recommended for those recovering from surgery.
Because it is so easily converted to
glucose, leucine helps to regulate blood sugar; a deficiency of
leucine produces symptoms similar to those of hypoglycemia, which
may include headaches, dizziness, fatigue, depression, confusion,
and irritability.
Natural sources of leucine include
brown rice, beans, meat, nuts, soy flour, and whole wheat. Leucine
is an essential amino acid, which means that it cannot be
manufactured in the body and must be obtained through dietary
sources. People that exercise a lot, have a low-protein diet, or
are seriously trying to build muscle mass should consider leucine
supplementation. Leucine is also available in stand-alone
supplemental form, but should always be taken together with the
other two branched-chain amino acids, isoleucine and valine. The
ideal balance is 2 milligrams of leucine and valine for each 1
milligram of isoleucine. Combination supplements that provide all
three of the BCAAs may be more convenient.
An excessively high intake of
leucine has also been linked to the development of pellagra, a
deficiency of the vitamin niacin that causes dermatitis, diarrhea,
and mental disorders. Too much leucine in the diet can disrupt
liver and kidney function and increase the amount of ammonia in the
body. People with impaired liver or kidney function should not take
isoleucine without first consulting a physician, as large doses of
amino acids may aggravate these conditions.
