Amino Acids - The building blocks of protein. There are twenty-four amino acids, which form countless numbers of different proteins. They all contain nitrogen, oxygen, carbon, and hydrogen. Amino acids are either essential or nonessential.
ESSENTIAL AMINOS must be derived from food or supplements. There are eight of them: L-ISOLEUCINE, L-LEUCINE, L-LYSINE, L-METHIONINE, L-PHENYLALANINE, L-TRYPTOPHAN, L-THREONINE, and L-VALINE. L-ARGININE and L-HISTIDINE, are essential for children to help with growth and dease prevention.
NONESSENTIAL AMINOS are manufactured internally in the quantities the body requires. Their names are GLYCINE, L-ALANINE, L-ASPARAGINE, L-ASPARTIC ACID, L-CITRULLINE, L-CYSTEINE, L-CYSTINE, L-GLUTAMIC ACID, L-GLUTAMINE, L-ORNITHINE, L-PROLINE, L-SERINE, TAURINE, and L-TYROSINE.
Description - The branched-chain amino acids (BCAAs) comprise the three essential amino acids L-leucine, L-isoleucine and L-valine. These amino acids are found in proteins of all life forms. Dietary sources of the branched-chain amino acids are principally derived from animal and vegetable proteins. Vegetables and juices contain small amounts of the free amino acids, which are also found in fermented foods like yogurt and miso.
L-leucine is also known as 2-amino-4-methylvaleric acid, alpha-aminoisocaproic acid and (S)-2-amino-4-methylpentanoic acid. It is abbreviated as Leu or by its one letter abbreviation L. Its molecular formula is C6H13NO2, and its molecular weight is 131.17 daltons. The structural formula is:
L-Isoleucine is also known as 2-amino-3-methylvaleric acid, alpha-amino-beta-methylvaleric acid and (2S, 3S)-2-amino-3-methylpentanoic acid. It is abbreviated as Ile or by its one letter abbreviation I. Its molecular formula is C 6H13NO2, and its molecular weight is 131.17 daltons. The structural formula is:
L-valine is also known as 2-aminoisovaleric acid, 2-amino-3-methylbutyric acid, alpha-aminoisovaleric acid and (S)-2-amino-3-methylbutanoic acid. It is abbreviated as Val, and its one letter abbreviation is V. Its molecular formula is C5H11NO2, and its molecular weight is 117.15 daltons. The structural formula is:
Although amino acids are not considered important energy sources(Some endurance athletes have been taking BCAA's in attempts to improve endurance and lessen fatigue this has yet to be proven), BCAAs serve as important fuel sources for skeletal muscle during periods of metabolic stress(exercise). Under such conditions, BCAAs may promote protein synthesis, suppress protein catabolism and serve as substrates for gluconeogenesis. BCAAs are mainly catabolized in skeletal muscle, stimulating the production of, among other substances, L-alanine and L-glutamine.
They act as nitrogen carriers which assist the muscles in synthesizing other amino acids needed for anabolic muscle action. In simpler terms, BCAA's combine simpler amino acids to form a complex whole muscle tissue. In this action, BCAA's stimulate production of insulin, the main function of which is to allow circulating blood sugar to be taken up by the muscle cells and used as a source of energy. This insulin production promotes amino acid uptake by the muscle.

RSP NutritionIs BCAA supplementation a necessary part of you training arsenal the answer could be yes or no depending on the level of fitness or sport participation level. If you are of average fitness level you can try BCAA supplementation but do so within the confines of a very good complete amino acid formula which is rich in BCAA's. If you are on the high end of the spectrum of physical exertions, BCAA supplementation can be very beneficial to your goals because as you body becomes more highly tuned nutrient balance is extremely important. Below are listed our recommendation for each class of individual. As with all supplements there is more research to be done and field studies to complete, but we will bring you the best advice today, tomorrow and beyond.
