Sucrose are oligosaccharid$$Glucose+fructose \rightarrow sucrose,.........Glucose+ Galactose= Lactose$$

aaronq · Answer

sucrose is a disaccharide, not oligo

anonymous · Answer

And oligosaccharides are disaccharides...Right? :/

aaronq · Answer

nope. oligo- means more than 3 but less than poly- ..how ever many that might be.

anonymous · Answer

Oligo=few...:I
More than 3 less than poly ?:/

aaronq · Answer

haha yeah, i haven't seen anywhere that defined poly or oligo accurately.

oligo = few , poly = more than a few 


lol thats what i go by

Anyways Thanks for correction..You're right Sucrose is Disaccharides..Sugar which composed of two monomers are disacchrides..:P

aaronq · Answer

no prob :P
