Lipoic acid (LA), also known as α-lipoic acid, alpha-lipoic acid (ALA) and thioctic acid, is an organosulfur compound derived from caprylic acid (octanoic acid). [3] ALA, which is made in animals normally, is essential for aerobic metabolism. It is also available as a dietary supplement or pharmaceutical drug in some countries.
Thioacetic acid is an organosulfur compound with the molecular formula CH 3 C(O)SH. It is a thioic acid: the sulfur analogue of acetic acid (CH 3 C(O)OH), as implied by the thio-prefix. It is a yellow liquid with a strong thiol-like odor. It is used in organic synthesis for the introduction of thiol groups (−SH) in molecules. [4]

Excessive consumption of elemental silver, silver dust or silver compounds can cause the skin to be colored blue or bluish-grey. This condition is called argyria. A similar skin color can result from prolonged exposure to gold, typically as a little-used medical treatment. The gold-induced greyish skin color is called chrysiasis. Argyria and ...
In addition to lactic acid bacteria, yeasts also have been reported to have a biopreservation effect due to their antagonistic activities relying on the competition for nutrients, production and tolerance of high concentrations of ethanol, as well as the synthesis of a large class of antimicrobial compounds exhibiting large spectrum of activity against food spoilage microorganisms, but also ...
Skin whitening, also known as skin lightening and skin bleaching, is the practice of using chemical substances in an attempt to lighten the skin or provide an even skin color by reducing the melanin concentration in the skin.
