متن کاملThe Precursor of Ascorbic Acid in Vitro
many sugars investigated, mannose caused a greater rise of ascorbic acid than any other sugar (Guha and Ghosh, 1934). These findings, however, could not be confirmed (Scheumert and Schieblich, 1937; Hawthorne and Harrison, 1937). The presence of traces of manganese is necessary for the successful synthesis of ascorbic acid from mannose and to a less extent from galactose and glucose in animal t...
متن کاملTHE PREPARATION OF cl-GALACTURONIC ACID FROM LEMON PECTIC ACID.*
A noteworthy advance in the knowledge of the constitution of the pectic compounds was afforded through the excellent researches of Ehrlich and his coworkers (1)) who discovered that d-galacturonic acid, an isomer of d-glucuronic acid, was a constituent of all pectic substances so far examined. Later researches showed that the pectic acid obtainable from sugar beet pectin (2) can be regarded as ...

متن کاملCOBALT PHTHALOCYANINE MODIFIED CARBON PASTE ELECTRODE AS A POTENTIOMETRIC SENSOR FOR DETERMINATION OF ASCORBIC ACID
A carbon Paste electrode modified with cobalt (II) phthalocyanine (CoPC) was used as a sensitive potentiometric sensor for determination of ascorbic acid in aqueous solutions. The potential response of the electrode is a linear function of ascorbic acid concentration over the range 5 10 to 10 M (?1- 1800 µg ML ) with a Nernstian slope of 56 mV at pH 7. The limit of detection was 0.2 µg ...
