The most common low carb coffee drink at starbucks is a Flat White. The pictures below are my own and should give you a rough idea of what your drink will look like. Acidic conditions favor reduction of the complex and, thereby, color development, showed that an antioxidant is present.I’ve loosely organized my recommendations around the drink categories listed on the Starbucks drive-thru menu. This reaction is nonspecific and any half-reaction which has a less-positive redox potential, under reaction conditions, than the Fe 3+/Fe 2+ complex half reaction will drive Fe 3+ complex reduction. At low pH, when a ferric complex is reduced to the ferrous form (Fe 2+), an intense blue color with an absorption maximum at 593 nm develops. The assay described here measures the ferric reducing ability of plasma (FRAP).

G-Biosciences’ FRAP assay kit is recommended for total antioxidant activity of single antioxidants in aqueous solution and added to plasma. Some biomolecules are also considered biologically active and clinically significant antioxidants, for example, transferrin, ferritin, lactoferrin, ceruloplasmin, hemopexin, haptoglobin, and uric acid. Substances with antioxidative properties are called antioxidants.Īntioxidative systems include antioxidative enzymes, that is, superoxide dismutase, catalase, glutathione peroxidase, glutathione-S-transferase, and nonenzymatic substrates, such as glutathione, uric acid, lipoic acid, bilirubin, coenzyme Q, vitamin C (L-ascorbic acid), vitamin A (retinol), vitamin E (tocopherol), flavonoids, carotenoids, and others.

Antioxidative effect includes protection of cells and cellular structures against harmful effect of free radicals, especially oxygen and nitrogen. Antioxidant capacity is an overall ability of organisms or food to catch free radicals and prevent their harmful effect.
