Sugar II

When we think of sugar, usually the standard white granulated sugar that is seen in packets comes to mind.
But in the scientific world, sugar is a far more complex subject. Molecules of complex sugar molecules are more commonly known as carbohydrates, while more simple sugar compounds are plainly “simple sugars.” In actuality, all sugars are carbohydrates – they contain a carbon, hydrogen, and oxygen in the empirical formula C_n (H_2 O)_n. The underscore _ indicates the location of a subscript. In this configuration, it can easily be seen that carbohydrates are hydrates of carbon molecules – hence the name carbohydrate. For simplicity, carbohydrates are usually written in the form C_n H_2n O_n with {n ∈ Z 3 ≤ n ≤ 7}.

Carbohydrates are the main energy source of all organisms. As I mentioned before, these sugars vary widely in chemical composition – from the simple monosaccharides and disaccharides to more complex oligosaccharides – which contain up to ten molecules of ‘simple’ sugars connected by bonds. The root -saccharide derives from the Latin saccharum and Greek sakcharon. The Greeks modified this from the Prankrit sakkharā and Sanskrit śarkarā – all to mean sugar or gravel. Mono-, di-, and oligo- roots all refer to the numbers of saccharides (one, two, and ‘few’, respectively).

So how do plants produce sugars that we consume?

All plants have an organelle chloroplast which contains a green photosynthetic pigment that produces the chemical compounds with the aid of radiant energy from the light of the sun. The photosynthetic pigment is also responsible for the varying colors of green in plants. Photosynthesis is the process in which plants use radial energy from the sun (in addition to water and carbon dioxide) to form a simple glucose sugars molecule C_6 H_12 O_6. This process yields the energy plants need to survive – and it then can manufacture the more complex sucrose and fructose combinations. The photosynthetic process can be represented in a chemical equation 6 CO_2 + 6 H_2 O + sunlight →3 C_6 H_12 O_6.

In the culinary realm, because sugar does not occur in the form of glucose in plants naturally – it is usually modified from other sugar. Glucose is the main form of sugar in corn syrup. There is a distinct difference from corn syrup and high-fructose corn syrup found in many processed foods. This difference is just how the syrup is produced and the enzymatic processes that occur in each.

How is normal corn syrup useful?

Because of its different chemical structure, glucose is known as a preventative measure for crystallization in simple syrup.

Simple syrup:

Although I still do not know why exactly it may be called simple – I know it is a simple combination of sugar and water; it also just happens to be very simpleto make. Simple syrup has many uses in the kitchen where a liquid form of sugar is required. The best example is adding sugar to cold drinks. Notice how it just settles to the bottom of the container…? It just does not want to dissolve.
