Cellobiose
Cellobiose is a disaccharide with the formula [HOCH2CHO(CHOH)3]2O. Cellobiose, a reducing sugar, consists of two β-glucose molecules linked by a β(1→4) bond. It can be hydrolyzed to glucose enzymatically or with acid. Cellobiose has eight free alcohol (OH) groups, one acetal linkage and one hemiacetal linkage, which give rise to strong inter- and intra-molecular hydrogen bonds. It can be obtained by enzymatic or acidic hydrolysis of cellulose and cellulose rich materials such as cotton, jute, or paper.
Treatment of cellulose with acetic anhydride and sulfuric acid, gives cellobiose octoacetate, which cannot engage in hydrogen bonding and is soluble in nonpolar organic solvents.

Sleepy Eyes
by: Marcy PlaygroundDreaming again
Warm in your arms
Sing me a song
Beautiful sound
And you love me
With your sleepy eyes
But you're not around
I'm riding a ghost
You're already gone
And I wake up to a cold day
Just another in a long line of cold days
Clear as a bell
There in my bed
Holding your hands
Beautiful hands
And you love me
With your sleepy eyes
But you're just a dream
I'm walking alone
And I should have known
You'd find another soul mate
