BIOCHEM | Oligosaccharides

Oligosaccharides

short chains of monosaccharides (less than 10 or less than 20)

Trisaccharide

three monosaccharides

Raffinose

• trisaccharide of C₁₈H₃₂O₁₆

• found in legume, beetroot, cabbage, cotton seed, broccoli

maltotriose

maltose + a-glucose

Tetrasaccharide

four monosaccharides

Stachyose

two galactose units, one fructose unit, one glucose unit

Pentasaccharide

five monosacharides

Verbascose

three galactose units, one fructose unit, and one glucose unit

maltopentose

maltotriose + 2(a-glucose)

Hexasaccharides

six sugar units

Heptasachharides, Octasaccharides, etc.

more than six sugar units

Fructooligosaccharides

• chains of fructose

• storage in plants

• found in agave, banana, onion, wheat,

Galactooligosaccharides

• galactose molecules

• formed in breast milk

• crucial in infant nutrition

• most common Human Milk Oligosaccharide (HMO) is 2’-fucosyllactose
