Biosynthesis of Polysaccharides01:26

Biosynthesis of Polysaccharides

528
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...

Cellulose and Pectic Polysaccharides

4.6K
 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...

Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

24.8K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Protein Glycosylation01:25

Protein Glycosylation

9.2K
Glycosylation, the most common post-translational modification for proteins, serves diverse functions. Adding sugars to proteins makes the proteins more resistant to proteolytic digestion. Glycosylated proteins can act as markers and receptors to promote cell-cell adhesion. Additionally, they have many essential quality control functions in the cell, such as correct protein folding and facilitating transport of misfolded proteins to the cytosol, which can be degraded.
Glycosylation occurs in...

Chemistry of Carbohydrates

89.1K
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...

Carbohydrate Metabolism01:36

Carbohydrate Metabolism

13.7K
Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...

  • Food Science
  • Plant Biology
  • Biochemistry

Background:

  • Edible fruits exhibit diverse structural profiles of bioactive polysaccharides.
  • These polysaccharides are influenced by various abiotic factors within different terrestrial biomes.
  • Understanding these relationships is crucial for food science and fruit development.

Purpose of the Study:

  • To comparatively analyze and review the structural profiles of bioactive polysaccharides from edible fruits across different biomes.
  • To correlate fruit polysaccharide structures, focusing on monosaccharide fractions, with biome-specific abiotic variables (temperature, rainfall, soil characteristics).
  • To explore analytical methods for glycosidic profiling and compare polysaccharide composition with macromolecular parameters.

Main Methods:

  • Extensive narrative literature review and comparative analysis of existing studies.
  • Focus on monosaccharide composition and glycosidic profiles of fruit polysaccharides.
  • Analysis of macromolecular parameters: degree of esterification, branching, and average molecular weight.

Main Results:

  • Identified biome-specific polysaccharide patterns: high galacturonic acid/arabinose in cold regions; xyloarabinan/galactan in arid areas.
  • Fruits experiencing water variations showed increased branching, acetylation, and lower esterification for stability.
  • Strong association observed between polysaccharide structure and ecological adaptations for fruit development.

Conclusions:

  • Fruit polysaccharide structures are strongly linked to ecological adaptations and abiotic conditions of their biomes.
  • These findings are vital for basic and applied food science, offering targets for engineering fruit resistance to abiotic stress.
  • The study guides future research beyond classical methodologies for fruit science.
