Summary The enzyme pronase released seven amino acids and also galactose and arabinose from fulvic acid. Hemicellulase released sugars and some amino acids. Removal of the amino acids lowered the molecular weight and gave a lower value for the C. E. C. Differential enzymic removal of carbohydrate and amino acids from the fulvic acid molecule reduced its viscosity. From this evidence it is concluded that the sugar and amino acids are linked to the aromatic core of fulvic acid.
