Introduction to Carbohydrates

12.7K
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...

Carbohydrate Metabolism

11.2K
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...

Sugars as Energy Storage Molecules

8.5K
Sugar (a simple carbohydrate) metabolism (chemical reactions) is a classic example of the many cellular processes that use and produce energy. Living things consume sugar as a major energy source because sugar molecules have considerable energy stored within their bonds. Consumed carbohydrates have their origins in photosynthesizing organisms like plants. During photosynthesis, plants use the energy of sunlight to convert carbon dioxide gas into sugar molecules, like glucose. Because this...

Carbohydrate Digestion

114.8K
Carbohydrate digestion and metabolism break down simple and complex carbohydrates from food into saccharides (i.e., sugars) for the body to use as energy. Carbohydrate digestion starts in the mouth during mastication, or chewing. The masticated carbohydrates remain intact in the stomach. Digestion resumes in the duodenum of the small intestine, where pancreatic alpha-amylase and brush border enzymes of the microvilli convert complex carbohydrates to monosaccharides. Finally, the monosaccharides...

Area of Science:

  • Microbiology
  • Gut Microbiome Research
  • Nutritional Science

Background:

  • Bifidobacteria are crucial for host health, producing beneficial organic acids from carbohydrates.
  • Understanding bifidobacterial sugar preference is vital for harnessing their probiotic potential.
  • Limited knowledge exists on the specific carbohydrate utilization patterns among Bifidobacterium species.

Purpose of the Study:

  • To investigate the sugar utilization preference (glucose vs. lactose) in various Bifidobacterium species.
  • To correlate sugar preference with genomic information and host environment.
  • To provide a systematic evaluation of Bifidobacterium sugar uptake.

Main Methods:

  • Culturing 40 Bifidobacterium species/subspecies on glucose and/or lactose.
  • Assessing preferential sugar utilization using high-performance thin-layer chromatography (HPTLC).
  • Conducting comparative genomic analysis of carbohydrate metabolism genes.

Main Results:

  • Identified Bifidobacterium strains with preferential utilization of either glucose or lactose.
  • Lactose-preferring strains predominantly possessed the lactose symporter (lacS) gene.
  • Isolate source correlated with sugar preference: human isolates preferred lactose, insect isolates preferred glucose.
  • Host milk lactose content and infant fecal lactose also indicated host-dietary influence.

Conclusions:

  • Bifidobacterium sugar preference is significantly influenced by host dietary habits and environment.
  • This study provides the first systematic analysis of sugar uptake preferences across diverse Bifidobacterium species.
  • Findings suggest host-specific adaptation in Bifidobacterium carbohydrate metabolism.
