Document Summary
Sum of all chemical reactions that occur in the body. Bioenergetics: converting foodstuffs (fats, proteins, carbohydrates) into energy. Oxidative formation of atp: anaerobic pathways. Pc breakdown and glycolysis: aerobic pathways. What is creatine: non-essential dietary element . found in meat and fish, greek derivative, kreas, meaning flesh, humans: made in 2 step process (liver and kidney), where is it found? (mostly)skeletal muscle, heart, spermatozoa, retinal cells. Creatine biosynthesis: 2 step process, step 1: kidney: arginine + glycine. Creatine biosynthesis: 2 step process, step 2: liver: guanidinoacetate + methionine. Creatine phosphate (phosphocreatine, pcr, crp: contains energy in phosphate bond. Idea increase the muscle"s stores of creatine phosphate . extends high intensity exercise and speeds muscle recovery. Types: creatine monohydrate (most popular, creatine anhydrous (con-cret, creatine phosphate, creatinol-o-phosphate. Creatine content: creatine anhydrous, creatine monohydrate , creatine malate , creatine citrate - Creatine solubility in water: greater solubility with creatine salts than creatine monohydrate.
