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,
Artificial nails players resort to artificial nails to prevent wear and chipping of natural nails. Artificial nails Artificial nails, also known as fake nails, false nails, fashion nails, nail enhancements, nail wraps, or nail extensions, are extensions placed over fingernails as fashion accessories. Some artificial nail designs attempt to mimic the appearance of real fingernails as closely as possible, while others may deliberately stray in favor of an artistic look. Unlike most manicures, artificial nails require regular upkeep; it is recommended that they are attended to, on average, every two weeks. Nonetheless, their versatility in terms of shape and design and comparatively
