Applications
DescriptionL-Norvaline, an amino acid nutritional supplements, is a nonessential amino acid that’s typically found in protein-rich foods, such as meat and eggs. And, it can also be made by the body from valine during normal metabolism. L-norvaline is frequently consumed by athletes as part of their workout supplement program. It is usually used for pre-workout drinks to boost energy and support post-workout recovery. During workouts, L-norvaline improves muscle tissue strength and endurance by providing massive amounts of oxygen and nutrients.
UsesL-Norvaline is a protein amino acid used as a skin-conditioning and anti-static agent. It is also used in method for reducing misincorporation of non-canonical branched-chain Amino Acids into recombinant proteins.
