aminos

Essential amino acidsThe nine essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.

Nonessential amino acids means that our bodies produce an amino acid, even if we don't get it from the food we eat.
They include: alanine, asparagine, aspartic acid, and glutamic acid.

Conditional amino acids are usually not essential, except in times of illness and stress.
They include: arginine, cysteine, glutamine, tyrosine, glycine, ornithine, proline, and serine.

Branched Chain Amino Acids (BCAA's), a group of three essential amino acids, are different from the other 17 amino acids in that in one of their roles, they are a primary source of fuel for skeletal muscles. This makes them of particular value and importance to elite athletes as far as sports supplements are concerned.
The branched chain amino acids are: valine, leucine, and isoleucine.

You do not need to eat essential and nonessential amino acids at every meal, but getting a balance of them over the whole day is important.

Аминокислота Свойства
ALANINE (Non-Essential Amino Acid)
Major component of connective tissue, key intermediate in the glucose alanine cycle, which allows muscles and other tissues to derive energy from amino acids
ARGININE (Non-Essential Amino Acid)
Enhanced immune system responses to bacteria, viruses and tumor cells; promotes wound healing and regeneration of the liver; causes the release of growth hormones; considered crucial for optimal muscle growth and tissue repair; increases secretion of insulin, glucagon; formation of collagen; precursor of creatine, gamma amino butyric acid (GABA, a neurotransmitter in the brain); may increase sperm count and T-lymphocyte response boosting the immune system
ASPARTIC ACID (Non-Essential Amino Acid)
Aids in the expulsion of harmful ammonia from the body. When ammonia enters the circulatory system it is highly toxic to the central nervous system. Recent studies have shown that aspartic acid may increase resistance to fatigue and increase endurance. Helps convert carbohydrates into muscle energy, builds immune system immunoglobulins and antibodies.
CYSTEINE (Non-Essential Amino Acid)
Detoxifies harmful chemicals in combination with L-aspartic acid and L-citruline, helps prevent damage from alcohol and tobacco use, stimulates white blood cell activity
CYSTINE (Non-Essential Amino Acid)
Functions as an antioxidant and is a powerful aid to the body in protecting against radiation and pollution. It can help slow down the aging process, deactivate free radicals, neutralize toxins; aids in protein synthesis, necessary for the formation of the skin and connective tissue. Aids in the healing processes and recovery from burns and surgical operations. Hair and skin are made up of 10- 14% cystine. Stimulates white blood cell activity and helps diminish pain from inflammation
GLUTAMIC ACID (Non-Essential Amino Acid)
Considered to be nature’s “brain food” by improving mental capacities, helps speed the healing of ulcers, gives a “lift” from chronic fatigue, helps control alcoholism, schizophrenia and the craving for sugar. Is a major precursor of glutamine, proline, ornothine, arginine, glutathione, and GABA.
GLUTAMINE (Non-Essential Amino Acid)
A most abundant amino acid, plays a key role in immune system functions, important source of energy, especially for kidneys and intestines during caloric restrictions. A brain fuel that is an aid to memory and a stimulant for intelligence and concentration.
GLYCINE (Non-Essential Amino Acid)
Releases oxygen for cell-making processes, makes hormones for immune system, helps make other amino acids, part of hemoglobin and cytochromes (enzymes involved in energy production), has a calming effect, used to treat manic depressive and aggressive individuals, produces glucagon which mobilizes glycogen, inhibits sugar cravings
HISTIDINE (Essential Amino Acid)
Part of hemoglobin, used for rheumatoid arthritis, allergic diseases, ulcers and anemia, major ultraviolet absorbing compound in skin, makes red and white blood cells, used for anemia, used for allergic diseases, digestive ulcers
DEFICIENCY SYMPTOMS: Poor hearing
HYDROXYPROLINE (Non-Essential Amino Acid)
Made from Proline to make collagen, strengthens ligaments, tendons, blood vessels and provides skin elasticity.
DEFICIECY SYMPTOMS: Easy bruising, internal bleeding, breakdown of connective tissue, ligaments, tendons and blood vessel damage. Deficiency of hydroxyproline will only occur if there is a deficiency of vitamin C, producing the skin lesions typical of the disease scurvy.
ISOLEUCINE (Essential Amino Acid - BCAA's)
A branched chain amino acid readily taken up and used for energy by muscle tissue, used to prevent muscle wasting in debilitated individuals, forms hemoglobin
LEUCINE (Essential Amino Acid - BCAA's)
Stimulants the upper brain to be more alert, a branched chain amino acid used as a source of energy, reduces muscle protein breakdown, modulates uptake of neurotransmitter precursors by the brain as well as the release of encephalins, which inhibit the passage of pain signals into the nervous system, promotes healing of skin and broken bones
LYCINE (Essential Amino Acid)
Insures the adequate absorption of calcium, helps form collagen (which makes up bone cartilage and connective tissues), aids in the production of antibodies, hormones and enzymes, effective against herpes, reduces viral growth. Lysine and Vitamin C together form L-carnitine, a biochemical that enables muscle tissue to use oxygen more efficiently, delaying chronic fatigue. Deficiency symptoms: chronic fatigue, inability to concentrate, irritability, bloodshot eyes, retarded growth, hair loss, anemia, reproductive problems, low levels can slow protein synthesis, affecting muscle and connective tissue
METHIONINE (Essential Amino Acid)
Supplies sulfur which prevents disorders of the hair, skin and nails, lowers cholesterol levels by increasing the liver’s production of lecithin, reduces liver fat and protects the kidneys, a natural chelating agent for heavy metals, regulates the formation of ammonia and creates ammonia-free urine which reduces bladder irritation, influences hair follicles and promotes hair growth, precursor of cystine and creatine, increases antioxidant levels (glutathione), reduces blood cholesterol levels
ORNITHINE (Non-Essential Amino Acid)
Increases growth hormone secretion, aids in immune and liver function, promotes healing
PHENYLALANINE (Essential Amino Acid)
Produces norepinephrine, a chemical that transmits signals between nerve cells and the brain, keeps you awake and alert, reduces hunger pains, functions as an antidepressant and helps improve memory, precursor of tyrosine, enhances learning, memory, mood and alertness, used in the treatment of some types of depression, is a major element in the production of collagen, suppresses appetite
PROLINE (Non-Essential Amino Acid)
Joints, tendons, connective tissue, helps maintain and strengthen heart muscle, mobilized for muscular energy, major constituent of collagen
SERINE (Non-Essential Amino Acid)
Storage source of glucose by the liver and muscles, strengthens the immune system by providing antibodies and immuno-globulins, synthesizes fatty acid sheath around nerve fibers, important in cells’ energy production, aids memory and nervous system function
TAURINE (Non-Essential Amino Acid)
Helps stabilize the excitability of membranes, which is very important in the control of epileptic seizures, taurine and sulfur are considered to be factors necessary for the control of many biochemical changes that take place in the aging process, aids in the clearing of free radical wastes, aids in the absorption and elimination of fats, acts as a neurotransmitter in some areas of the brain and retina
THREONINE (Essential Amino Acid)
Constituent of collagen, elastin, and enamel protein, helps prevents fat build-up in the liver, helps the digestive and intestinal tracts function more smoothly, assists metabolism and assimilation, one of the amino detoxifiers, generally low in vegetarians
TRYPTOPHAN (Essential Amino Acid)
Natural relaxant, induces normal sleep, reduces anxiety and depression, the treatment of migraine headaches, immune system, reduces the risk of artery and heart spasms, works with lysine in reducing cholesterol levels, precursor of neurotransmitter serotonin, which exerts a calming effect, releases of growth hormones. It is found abundantly in Turkey meat
TYROSINE (Non-Essential Amino Acid)
Transmits nerve impulses to the brain, depression, elevates mood, memory, mental alertness, thyroid, adrenal and pituitary glands, precursor of the neurotransmitters dopamine, norepinephrine, epinephrine, thyroid, growth hormones and melanin (the pigment responsible for skin and hair color)
VALINE (Essential Amino Acid - BCAA's)
Promotes mental vigor, muscle coordination and calm emotions, a branched chain amino acid, not processed by the liver, influences brain uptake of other neurotransmitter precursors (tryptophan, phenylalanine and tyrosine).
