# Define carbohydrates and identify their basic subunits?

Nov 7, 2016

Hydrates of carbon are carbohydrates. The basic subunits of carbohydrates are called monosaccharides.

#### Explanation:

Carbohydrates are compounds of carbon, hydrogen and oxygen of the form ${C}_{m} {H}_{2 n} {O}_{n}$. (See this answer to see why!) The simple unit of ratio of carbon, hydrogen and oxygen in carbohydrates is $1 : 2 : 1$.

The basic monomers subunits of carbohydrates are called monosaccharides. Monosaccharides join together by polymerzation to for a polymer called a polysaccharide.

Here's a hierarchical breakdown of the subunits you might hear for a simple sugar.

Monosaccharides - one individual unit
Disaccharides - two monosaccharides joined by covalent bonds
Oligosaccharides $3 - 20$ monosaccharides
Polysaccharides a lot $\left(100 +\right)$ of monosaccharides.
