Carbohydrate Metabolism

14.2K
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...

Overview of Metabolism

38.2K
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.
Plant Metabolism
Sunlight, the primary source of energy in plants, is first absorbed by the chlorophyll pigments present in their leaves. Plants then use this energy to carry out photosynthesis, where water is oxidized into oxygen and carbon dioxide...

Regulation of Metabolism

11.6K
Cellular needs and conditions vary from cell to cell and change within individual cells over time. For example, the required enzymes and energetic demands of stomach cells are different from those of fat storage cells, skin cells, blood cells, and nerve cells. Furthermore, a digestive cell works much harder to process and break down nutrients during the time that closely follows a meal compared with many hours after a meal. As these cellular demands and conditions vary, so do the amounts and...

Metabolic Rate01:25

Metabolic Rate

1.2K
The human body is a powerhouse of energy, with every cell performing numerous functions that require energy. This energy production and consumption is measured by the metabolic rate, which quantifies the total heat generated by all the body's chemical reactions and mechanical work. This measurement helps to determine the rate of kilocalorie (kcal) consumption needed to fuel all ongoing activities.
The Basal Metabolic Rate (BMR) measures the energy expended at rest.
Several factors influence...

Introduction to Metabolism

Metabolism encompasses all biochemical reactions in a living organism, facilitating both the breakdown and synthesis of biomolecules. These metabolic processes are categorized into catabolic and anabolic pathways, which operate in a coordinated manner to ensure energy balance and cellular function.Catabolic Pathways and Energy ReleaseCatabolic pathways involve the breakdown of complex macromolecules such as carbohydrates, lipids, and proteins into smaller structures like monosaccharides, fatty...

Summary
This summary is machine-generated.

Metabolic encephalopathies (ME) are common, often reversible causes of altered brain function. Rapid diagnosis and treatment of ME are crucial for a favorable outcome, especially in older, comorbid patients.

Area of Science:

  • Neurology
  • Internal Medicine
  • Critical Care Medicine

Background:

  • Metabolic encephalopathies (ME) are frequent causes of ICU admission, potentially leading to poor outcomes, particularly in elderly patients.
  • ME involves altered brain function due to substance deficiency or accumulation, often in comorbid patients, complicating diagnosis and management.
  • Symptoms range from mild cognitive impairment to coma and myoclonus, with diagnosis often suggested by the absence of other causes.

Purpose of the Study:

  • To review the pathophysiology, causes, and diagnostic challenges of metabolic encephalopathies.
  • To outline the diagnostic work-up, including essential tests like EEG and MRI.
  • To propose a diagnostic and therapeutic strategy for managing ME patients.

Main Methods:

  • Literature review of pathophysiological mechanisms, causes, and clinical presentations of ME.
  • Discussion of diagnostic tools, including biological sampling, brain MRI, and electroencephalogram (EEG).
  • Analysis of treatment strategies, focusing on etiological correction.

Main Results:

  • ME is characterized by altered brain function due to metabolic disturbances, often reversible with prompt intervention.
  • Diagnostic clues include altered mental status, movement disorders, and exclusion of other conditions.
  • Treatment primarily involves correcting the underlying metabolic cause.

Conclusions:

  • Metabolic encephalopathies are significant causes of neurological dysfunction requiring timely diagnosis and management.
  • While often reversible, ME can lead to poor outcomes if not treated promptly.
  • A strategic approach to diagnosis and treatment is essential for improving patient outcomes.
