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,
Nissan Nails Nissan Nails The Nissan Nails is a concept pickup truck built by Nissan. It was introduced in 2001 at the Tokyo Auto Show. The Nails is powered by a front-mounted 1.5 L Inline-four engine producing around , with power going to the front wheels. It features a 2-door, 2-seater pickup body style with body panels that Nissan claims are manufactured to be dent and scratch resistant. The load bed of the Nails is placed beneath the wheels, unlike many contemporary pickup trucks, allowing for a low, flat load floor, which makes it easier to load in heavy objects. It also
