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 ...
