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.

Chemical Information
Molecular Weight 150.13
Formula C5H10O5
CAS Number 5328-37-0
Form Solid
Solubility (25°C) Water 100 mg/mL
Storage RT
Conversion of different model animals based on BSA (PMID: 27057123)
Species Mouse Rat Rabbit Guinea pig Hamster Dog
Weight (kg) 0.02 0.15 1.8 0.4 0.08 10
Body Surface Area (m2) 0.007 0.025 0.15 0.05 0.02 0.5
Km factor 3 6 12 8 5 20
Animal A (mg/kg) = Animal B (mg/kg) multiplied by  Animal B Km
Animal A Km

For example, to modify the dose of Compound A used for a mouse (20 mg/kg) to a dose based on the BSA for a rat, multiply 20 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for Compound A of 10 mg/kg.

Glycogen is a branched polymer of glucose synthesized by animal cells for energy storage and release. Oyster glycogen has been used to induce inflammation and to promote extravasation of granulocytes and neutrophils in animal models after intraperitoneal injection. Glycogen also acts as a vascular permeability probe.
