What is Nectar made of?

Postby Ciwan » Mon Sep 24, 2007 6:27 am

Hi guys

I was watching Life In The Undergrowth presented by the "God" of documentaries (Sir David Attenborough).

The part about insects taking to the air came up, and how most insects depended on Nectar from plants.

I was just wondering what is in this magical Nectar?

The name of the most abundant molecules found in Nectar would be a good place to start :D

Thanks Guys/Girls :D

it's sweet, so first guess would be fructose.

I have not actually read this anywhere, but i am sure it must be sucrose that makes nectar sweet. Since sucrose is the glucose of plants. they use the stuff for everything. And sucrose synthase is such a key enzyme in plant metabolism.

i was wrong
"The various types of nectars can be ordered into three groups according to sugar content: sucrose prevalent, glucose and fructose prevalent, and equal amounts of sucrose, glucose, and fructose"

You can find the full composition of nectar here: http://www.bb.iastate.edu/necgex/Nectar.htm
