翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Phenolic acid ： ウィキペディア英語版 Phenolic acid Phenolic acids or phenolcarboxylic acids are types of aromatic acid compound. Included in that class are substances containing a phenolic ring and an organic carboxylic acid function (C6-C1 skeleton). There are several categories of phenolic acids including: *Monohydroxybenzoic acids: salicylic acid, 3-Hydroxybenzoic acid, 4-Hydroxybenzoic acid * *Some esters of this group include paraben, methyl paraben, propyl paraben *Dihydroxybenzoic acids: vanillin, vanillic acid, gentisic acid, protocatechuic acid *Trihydroxybenzoic acids: gallic acid, ellagic acid, syringic acid, eudesmic acid, phloroglucinol carboxylic acid * *This type of phenolic acids (especially gallic acid, ellagic acid) is a component of hydrolysable tannins. == Occurrences == Phenolic acids can be found in many plant species. Their content in dried fruits can be high. Natural phenols in horse grams (''Macrotyloma uniflorum'') are mostly phenolic acids, namely 3,4-dihydroxy benzoic, ''p''-hydroxy benzoic, vanillic, caffeic, ''p''-coumaric, ferulic, syringic and sinapinic acids.〔Identification and quantification of phenolic acids in Macrotyloma uniflorum by reversed phase HPLC. Kawsar, S.M.A., E. Huq, N. Nahar and Y. Ozeki, Am. J. Plant Physiol., 3: 165-172, 2008, 〕 Phenolic acids can be found in mushroom Basidiomycetes species. It is also a part of the humic substances, which are the major organic constituents of soil humus. Many phenolic acids can be found in human urine. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phenolic acid」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
