Which of the following carbohydrate is polymerized through alpha 1,4 glycosidic linkages?
Correct answer: C. Starch
- A. Amylase
- B. Sucrose
- C. Starch
- D. Lactose
Explanation
The carbohydrate that is polymerized through alpha 1,4 glycosidic linkages is starch. Starch is a polysaccharide composed of repeating glucose units. It is the primary energy storage molecule in plants and is found in various plant-based foods such as grains, potatoes, and legumes. The alpha 1,4 glycosidic linkages in starch connect the glucose monomers, forming a linear chain called amylose. Additionally, starch can have branched structures known as amylopectin, where additional alpha 1,6 glycosidic linkages create branching points within the polymer.

About Carbohydrates
Carbohydrates are organic compounds classified as monosaccharides, disaccharides and polysaccharides according to their structure and hydrolysis products. The topic covers glycosidic bonds, glucose and fructose, sucrose, lactose and maltose, starch, glycogen and cellulose, along with their roles in energy storage, structural support and food tests.
