ARGININE Keep balance of insulin hormon Help detoxification of liver. Increase imun system. Inhibit growth of tumor cell and cancer. Increase ability of macrofag fagocitosys. Synthesis polyamin (protein for repair tissue of body and cure injury).

ARGININE... Merupakan substrat bagi produksi NO yang penting peranannya dalam menjaga kelapangan pembuluh darah (vasodilatasi). Melalui reaksi urea dan ornitin, arginin akan menghasilkan prolin yang selanjutnya membentuk kolagen jika tersedia vitamin C dalam jumlah memadai. Melalui pembentukan glutamat, arginin juga menghasilkan glutation yang berperanan dalam memelihara daya tahan sel, termasuk sel-sel lemak pada kulit.

GLUTAMINE Have a role to form gluthatione (with S from foods, eg : garlic, will form gluthation sulfihydril or GSH). GSH have a role to form gluthatione peroxidase (GPx). Have a role to form colagen, nucleotide and fosfolipide (important to production new cells). Become fast repair broken tissue of body (because of injury, etc).

TRYPTOPHAN Precursor of melatonin (stimulus hormon for sleep).melatonin Precursor of serotonin (suatu transmitter on nerve system ).serotonin Precursor of niasin.niasin

CYSTEIN Maker of gluthatione Protect cell from radicals and radiation effect. Protect liver and brain from alcohol and cigarette. Important to therapy of bronchitis, emphysema, TBC, and rheumatoid arthritis.

CYSTINE Help to keep pancreas healthy Stabilize blood sugar level and carbohydrat metabolism. Decrease alergy symptom (from foods). Important to form skin and have a role to cure injury. Help to cure bronchitis. Increase leucocyt cell activity.

Branced Chain Amino Acid (BCAA) Peptide Terdiri dari : leusin, isoleusin dan valin Function : mencegah kelelahan

Others Soy Protein Isolate (SPI) : decrease triglyceride level and cholesterol level, but increase HDL cholesterol level. Isolate Whey Protein (WPI) : antimicrobe, immuno modulator, antioxidant, and decrease hypertensi Lactoferin : glucoprotein (antioxidant, immuno modulator)
