Uses
D-Altrose is the epimer of D-glucose at C3 and have recently been discovered to possess antioxidant properties by the suppression of reactive oxygen species production in mitochondria due to competiti
on with D-glucose at the cellular level.
Definition
An aldohexose that is isomeric with glucose, tallose, allose, and others.
Purification Methods
Crystallise D-altrose from aqueous EtOH. If it is obtained by the hydrolysis of the acetate, then it may contain sodium and acetate ions. Ions are best removed by dissolving in H2O, passing through suitable columns of ion-exchange resins, e.g. Amberlite IR-120 and Duolite A, and concentrating in a vacuum to a syrup. This is dissolved in MeOH, filtered and evaporated in a vacuum desiccator over granular CaCl2. The thick syrup is inoculated with seed crystals, stirred, and before it sets to a magma of crystals, transfer the crystals with MeOH to a Büchner funnel. Recrystallise them in the same way. -D-Altrofuranoside has initial [] D ~-69o (c 4, H2O) which mutarotates to +33o.

Check Digit Verification of cas no
The CAS Registry Mumber 1990-29-0 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,9,9 and 0 respectively; the second part has 2 digits, 2 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 1990-29:
(6*1)+(5*9)+(4*9)+(3*0)+(2*2)+(1*9)=100
100 % 10 = 0
So 1990-29-0 is a valid CAS Registry Number.

Four new diterpene glycosides, virescenosides R1 (1), R2 (2), R3 (3) and Z (4) were isolated from a marine strain of Acremonium striatisporum KMM 4401 associated with the holothurian Eupentacta fraudatrix. Structures of 1-3 were determined as the corresponding biosides having isopimaradiene-type aglycons with additional oxidation and unsaturation patterns. Virescenosides Z (4) was structurally identified as altroside, containing 7-en-6-one group in the tricyclic aglycon moiety. The compounds 1-4 were examined for inhibition of non-specific esterase activity in mouse lymphocytes.
