Used as an alternate carbon source for wild-type yeast. Raffinose is a trisaccharide composed of galactose, glucose, and fructose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, other vegetables, and whole grains. Raffinose can be hydrolyzed to D-galactose and sucrose by the enzyme α-galactosidase (α-GAL), an enzyme not found in the human digestive tract. α-GAL also hydrolyzes other α-galactosides such as stachyose, verbascose, and galactinol, if present. The enzyme does not cleave β-linked galactose, as in lactose.||The raffinose family of oligosaccharides (RFOs) are alpha-galactosyl derivatives of sucrose, and the most common are the trisaccharide raffinose, the tetrasaccharide stachyose, and the pentasaccharide verbascose. RFOs are almost ubiquitous in the plant kingdom, being found in a large variety of seeds from many different families, and they rank second only to sucrose in abundance as soluble carbohydrates.||Synonyms:|D-(+)-Raffinose; Melitose, Melitriose; O-a-D-Galactopyranosyl-(1->6)-a-D-glucopyranosyl-ß-D-fructofuranoside||CAS No:|17629-30-0||Molecular Formula:|C18H32O16•5H2O||Molecular Weight:|594.51||Purity:|≥98%||Appearance:|White, crystalline powder||Solubility (10%):|Colorless, clear, complete after autoclaving||Glucose: |≤0.02%||Source:|Gossypium hirsutum L.||Identification (FTIR):|Complies||Loss on Drying: |13-17%||Residue on Ignition: |0.1%||Specific Rotation:|+103° to +108°||Melting Point:|78-82°C||Heavy Metals:|≤0.001%||Lead (Pb):|≤0.0002%||Arsenic (As):|≤0.0002%|||Storage:|RT|||Meets or Exceeds USP/NF Specifications
