Summary
Cereal heteroxylans, like arabinoxylans, significantly impact dough properties and bread quality. These dietary fibers also offer health benefits, potentially alleviating diseases such as diabetes and colon cancer.
Area of Science:
- Carbohydrate Chemistry
- Food Science
- Nutritional Science
Background:
- Non-cellulosic polysaccharides in cereals, primarily arabinoxylans and beta-glucans, influence dough rheology, starch retrogradation, and bread quality.
- Arabinoxylans are key components affecting water absorption and rheological properties.
- (1 --> 3),(1 --> 4)-beta -glucans function as biological response modifiers, potentially modulating immune responses.
Purpose of the Study:
- To review the isolation, purification, characterization, and structural elucidation of cereal heteroxylans.
- To discuss the functional and nutritional attributes of cereal heteroxylans.
- To emphasize recent characterizations of finger millet arabinoxylans.
Main Methods:
- Review of existing literature on cereal heteroxylans.
- Analysis of structural complexity using modern carbohydrate chemistry techniques.
- Focus on isolation and purification methods.
Main Results:
- Arabinoxylans significantly influence water balance, dough rheology, and starch retrogradation.
- Heteroxylans are classified as dietary fiber with potential health benefits for diabetes, atherosclerosis, and colon cancer.
- Detailed structural investigations of cereal heteroxylans remain challenging due to their complexity.
Conclusions:
- Cereal heteroxylans, particularly arabinoxylans, play a crucial role in cereal-based food functionality.
- These polysaccharides offer significant nutritional benefits as dietary fiber.
- Further research into the complex structures of cereal heteroxylans is warranted.

01:15Cellulose and Pectic Polysaccharides
Every plant cell has a cell wall that protects the cell, provides structural support, and gives the cell shape. Cellulose, the main structural component of the plant cell wall, makes up over 30% of plant matter. It is the most abundant organic compound on earth. Cellulose is an unbranched polysaccharide composed of linear chains of glucose molecules linked by β (1→4) glycosidic bonds.
As a cell matures, its cell wall specializes according to its type. For example, the parenchyma cells of...

03:25Chemistry of Carbohydrates
Carbohydrates are an essential part of the diet in humans and animals. Grains, fruits, and vegetables are natural sources of carbohydrates that provide energy to the body, particularly through glucose, a simple sugar that is a component of starch and an ingredient in many staple foods. The stoichiometric formula (CH2O)n, where n is the number of carbons in the molecule represents carbohydrates. In other words, the ratio of carbon to hydrogen to oxygen is 1:2:1 in carbohydrate molecules. This...
01:34Introduction to Carbohydrates
Carbohydrates, proteins, and fats are the primary macronutrients in the human diet. However, carbohydrates are the most favored source of energy in the body. They can be found in a wide variety of foods, including whole grains, fruit, and vegetables, in various forms, such as sugars, starch, and dietary fiber. Based on their structure, carbohydrates are classified into three main classes— monosaccharides, disaccharides, and polysaccharides. The body's cells can only utilize simple...

Overview
01:26Biosynthesis of Polysaccharides
Polysaccharides such as glycogen and starch are synthesized from nucleoside diphosphate sugars, primarily uridine diphosphate glucose (UDPG) and adenosine diphosphate glucose (ADPG). These activated glucose donors act as key intermediates in carbohydrate metabolism and biosynthesis. UDPG primarily involves glycogen synthesis in animals and many bacteria, while ADPG plays a fundamental role in starch synthesis in plants and certain bacteria.UDPG is formed when glucose-1-phosphate reacts with...
01:15Carbohydrates: Dietary Sources and Requirements
Carbohydrates are predominantly obtained from plant sources. With the exception of lactose found in milk and insignificant glycogen amounts in meat, most consumed carbohydrates have plant origins. Monosaccharides and disaccharides, or sugars, can be sourced from fruits, honey, milk, sugar cane, and sugar beets. Grains and vegetables are rich in the polysaccharide starch. Two types of polysaccharides provide fiber: cellulose, which is abundant in many vegetables, forms undigestible roughage or...
