L-Arabinose

Preparation

By partial hydrolysis of mesquite gum.

benefits

L-Arabinose can play an important role in the management of blood glucose and insulin levels related to sucrose intake. The addition of L-Arabinose to a sugar containing diet has the following direct benefits: 1) up to 60% reduction of the glucose peak level related to sucrose consumption, 2) up to 60% suppression of the insulin peak level related to sucrose consumption, and 3) a sustained release of glucose to the body over a longer period of time. A low glycemic diet may have benefits like reduction of heart disease, lowering of blood cholesterol, management of body weight and composition, and prevention of type 2 diabetes. A low insulinic diet may lead to lower fat storage and prevention of pre-diabetes incidence. Sustained glucose release over a longer period of time has advantages for athletes and other people that value a responsible and healthy diet.

Flammability and Explosibility

Notclassified

Biological Activity

L-Arabinose is the naturally occurring isomer and is a constituent of plant polysaccharides. Most bacteria contain an inducible arabinose operon that codes for a series of enzymes and transporters that allows L-arabinose to be used as the sole carbon source in microbial culture.

Biochem/physiol Actions

L-(+)-Arabinose is a naturally occurring pentose sugar that has been shown to decrease lipogenesis in rat models due to its ability to inhibit sucrase activity.

Definition

l-enantiomers occur naturally. lArabinose is common in vegetable gums, especially arabic.

Application

L-Arabinose is used as a substrate to identify, differentiate and characterize pentose sugar isomerase(s). L-Arabinose is used in the bioproduction of L-ribose.L-(+)-Arabinose is a pentose sugar that occurs naturally in corn fiber gum and acacia gum.L-(+)-Arabinose is used as a key starting material in the total synthesis of (+)-ambruticin, zaragozic acid A, (?)-radicamine B and (+)-herbarumin I.
