You Are Like Carbohydrates
A song about carbohydrate structure. The lyrics move from single monosaccharides through the covalent bonds that link them into polysaccharides, and show how branching and different sugar structures change what a carbohydrate does. Select any highlighted line to see the biology behind it.

Verse 1
You came in simple, sweet, and clear,
One small sugar drawing me near.
But something changed when we got close.
I was another single piece,
You were the rhythm under me.
Then every moment pulled us tight,
Pre-Chorus
Nothing stays alone.
We become something more.
Chorus
You are like carbohydrates,
Every memory connects us,
You can build me straight and steady,
You can branch in every way.
From a simple sugar beginning
To a chain that wants to stay.
You are like carbohydrates,
Every part of you combines.
Verse 2
Some love moves in a single row,
Linear pathways, steady and slow.
But you are never just one road,
You branch wherever feelings go.
One bond opens into two,
More directions leading back to you.
Simple pieces, side by side,
Building something deep and wide.
Small beginnings, stronger form,
A complex structure we transform.
Pre-Chorus
Nothing stays alone.
We become something more.
Chorus
You are like carbohydrates,
Every memory connects us,
You can build me straight and steady,
You can branch in every way.
From a simple sugar beginning
To a chain that wants to stay.
You are like carbohydrates,
Every part of you combines.
Bridge
Larger patterns start to take shape.
You are every bond between us,
Every layer, every memory.
Final Chorus
You are like carbohydrates,
Every moment connects us,
Covalent bonds that hold through time.
You can build me straight and steady,
You can branch and still remain.
From a single sugar beginning
To a long and living chain.
You are like carbohydrates,
More than sweetness, more than signs.
Outro
You started simple.
So did I.
Now we are linked
In every line.
Concepts covered
Monosaccharides as carbohydrate monomersMonosaccharides are single sugar molecules such as glucose, fructose, and galactose. They can serve as immediate energy sources or as monomers used to build larger carbohydrates.
Polymerization by dehydration synthesisEach new link forms by dehydration synthesis, which removes a hydrogen ion from one monomer and a hydroxyl group from the other, so the equivalent of a water molecule is lost as the covalent bond forms. Repeating that reaction many times is polymerization, the process that grows the chain.
Simple sugars and complex carbohydratesMonosaccharides are the simple sugars, and many of them connected together form the complex carbohydrates called polysaccharides. Going from single units to a large polymer changes the molecule's size and shape, and that changes the role it can play in a living system.
Covalent bonds between sugarsMonosaccharides can be connected by covalent bonds to form larger carbohydrates. Dehydration synthesis builds these polymers, while hydrolysis breaks them into smaller molecules.
PolysaccharidesA polysaccharide is a complex carbohydrate made from many monosaccharide monomers connected by covalent bonds. These polymers may be linear or branched.
Carbohydrate structure and functionThe kinds of sugar monomers and the way they are linked and branched affect a carbohydrate's three-dimensional structure. Those structural differences help carbohydrates perform roles such as energy storage and structural support.
Different monosaccharide structuresGlucose and fructose are both monosaccharides, but their structures differ. Monosaccharides serve as the monomers that can be connected to build larger carbohydrates.
Carbohydrate branchingComplex carbohydrates can form linear chains or branched structures. The way their monomers are connected helps determine the structure and function of the carbohydrate.
Carbohydrates are more than sweetnessSweetness describes simple sugars, but most carbohydrates in living things are large polymers instead. Starch, glycogen, and cellulose are complex carbohydrates built from many monosaccharide monomers, and they take on roles such as energy storage and structural support.
