Thioglycolic acid corresponding disulfide (2-[(carboxymethyl)disulfanyl]acetic acid or dithiodiglycolic acid): Thioglycolic acid, usually as its dianion, forms complexes with metal ions. Such complexes have been used for the detection of iron, molybdenum, silver, and tin. Thioglycolic acid reacts with diethyl acetylmalonate to form acetylmercaptoacetic acid and diethyl malonate, the reducing agent in conversion of Fe(III) to Fe(II). Scientist David R. Goddard, in the early 1930s, identified TGA as a useful reagent for reducing the disulfide bonds in proteins, including keratin (hair protein), while studying why protease enzymes could not easily digest hair, nails, feathers, and such. He realized that while the disulfide bonds,
Revival Soy milk protein shakes. Research also has suggested that Revival Soy protein shakes might support healthy skin, hair, and nails. A research study conducted by a board-certified dermatologist assigned postmenopausal women (50–65 years of age) with mild to moderate photoaging to drink either one Revival Soy protein shake or to remain on their normal diet for 6 months. After 6 months of dietary soy consumption, improvements were seen in facial wrinkling, discoloration, and overall appearance. Also, improvement was noted in nail roughness, ridging, flaking, splitting, and overall appearance at the end of the intervention period. Improvements in hair health were evident
