Expert Answer:

Succus entericus also called intestinal juice is a fluid that is secreted in small quantity in the small intestine. The secretions of the brush border cells of the mucosa alongwith the secretions of the goblet cells constitute this intestinal juice. It is highly variable in constitution, and contains various enzymes (such as erepsin, lipase, lactase, invertase, enterokinase, dipeptidases, nucleosidases and maltase) and mucus.
 
Enterokinase activates the inactive trypsinogen into active trypsin.
Erepsin further digests polypeptides into amino acids, completing protein digestion.
Invertase breaks up saccharose into dextrose and levulose
Maltase, whose action breaks up maltose into two glucose molecules
Lactase breaks up lactose into glucose and galactose.
Dipeptidases convert dipeptides into amino acids.
Lipases convert diglycerides and monoglycerides into fatty acids and glycerol.
Nucleosidases act on nucleosides and convert them into sugars and bases.
