Application

D-(−)-Arabinose is a D-ribose analogue present in sugar polymers such as the arabinogalatans of mycobacterial cell walls and plant tissues. D-Arabinose is a substrate used to identify, differentiate and characterize arabinose isomerase(s) that have commercial value in the production of tagatose, a low calorie sweetener.

Biochem/physiol Actions

D-Arabinose is a reducing sugar. It is a pentose analog of D-ribose that is a constituent of mycobacterial cell wall arabinogalactans. It is also a substrate for D-erythroascorbic acid synthesis in yeast.

Major depressive disorder (MDD) affects millions of patients; however, the pathophysiology is poorly understood. Rodent models have been developed using chronic mild stress or unavoidable punishment (learned helplessness) to induce features of depression, like general inactivity and anhedonia. Here we

Dopaminergic neurons serve multiple functions, including reinforcement processing during associative learning [1-12]. It is thus warranted to understand which dopaminergic neurons mediate which function. We study larval Drosophila, in which only approximately 120 of a total of 10,000 neurons are

It is now recognized that certain polysaccharides can exhibit anti-inflammatory activity, including the glycosaminoglycan (GAG) heparin that is widely used as an anti-coagulant drug. However, it would be desirable to identify molecules that retain the anti-inflammatory actions of heparin, but

Gustatory stimuli allow an organism not only to orient in its environment toward energy-rich food sources to maintain nutrition but also to avoid unpleasant or even poisonous substrates. For both mammals and insects, sugars-perceived as "sweet"-potentially predict nutritional benefit. Interestingly
