Upon acid
Almost 30% of the cocoon of the parasitic beetle Larinus
maculatus consists of the carbohydrate trehalose.
Trehalose was subjected to exhaustive methylation, which
hydrolysis, trehalose gives D-glucose as the only product.
converts all available OH groups to OCH3 groups; this was
and releases the methyl groups from all anomeric carbons
followed by mild hydrolysis in acid which breaks the linkage
without affecting any other OCH3 groups in the structure.
Following exhaustive methylation and subsequent hydrolysis
of trehalose with aqueous acid, only one product, 2,3,4,6-
tetramethylglucose, is obtained.

Step 1

Carbohydrates or carbs are macronutrient consisting of Carbon, hydrogen and oxygen atoms. In nature they are organic compounds which are aldehydes and ketones with many hydroxyl groups bound to it. Carbohydrates are important nutrients along with proteins and fats present in foods, drinks etc. Carbohydrates are classified into monosaccharides, disaccharides and oligosaccharides. These carbohydrates are metabolized into monosaccharides by various enzyme which later serves as fuel for energy generation.
