Inborn Errors of Metabolism01:20

Inborn Errors of Metabolism

1.1K
Phenylketonuria (PKU) is a protein metabolism disorder characterized by high blood levels of the amino acid phenylalanine. This results from a mutation in the gene responsible for phenylalanine hydroxylase, an enzyme that converts phenylalanine into tyrosine. When this enzyme is deficient, phenylalanine builds up in the blood, leading to symptoms such as vomiting, rashes, seizures, growth deficiency, and severe mental retardation. An early diagnosis and a diet restricting phenylalanine intake...

Protein Import into the Peroxisomes01:27

Protein Import into the Peroxisomes

4.4K
Cells contain membrane-bound organelles called peroxisomes that oxidize organic molecules by transferring hydrogen atoms to oxygen, producing hydrogen peroxide. Peroxisomes enzymatically convert the released hydrogen peroxide into water and oxygen.
Peroxisomal Protein Import:
Peroxisomes lack the genetic machinery required to code for their own proteins. Hence, most peroxisomal membrane, lumenal and transmembrane proteins are synthesized in the cytoplasm or ER and transported to the peroxisome...

Pyruvate Oxidation01:15

Pyruvate Oxidation

147.3K
After glycolysis, the charged pyruvate molecules enter the mitochondria via active transport and undergo three enzymatic reactions. These reactions ensure that pyruvate can enter the next metabolic pathway so that energy stored in the pyruvate molecules can be harnessed by the cells.
First, the enzyme pyruvate dehydrogenase removes the carboxyl group from pyruvate and releases it as carbon dioxide. The stripped molecule is then oxidized and releases electrons, which are then picked up by NAD+...

Electron Transport Chain: Complex I and II01:46

Electron Transport Chain: Complex I and II

11.8K
The mitochondrial electron transport chain (ETC) is the main energy generation system in the eukaryotic cells. However, mitochondria also produce cytotoxic reactive oxygen species (ROS) due to the large electron flow during oxidative phosphorylation. While Complex I is one of the primary sources of superoxide radicals, ROS production by Complex II is uncommon and may only be observed in cancer cells with mutated complexes.
ROS generation is regulated and maintained at moderate levels necessary...

Radical Autoxidation01:20

Radical Autoxidation

2.5K
The oxidation of an organic compound in the presence of air or oxygen is called autoxidation. For example, cumene reacts with oxygen to form hydroperoxide. Autoxidation involves initiation, propagation, and termination steps. Many organic compounds are susceptible to autoxidation—especially ethers in the presence of oxygen, which form hydroperoxides. Even though this reaction is slow, old ether bottles contain small amounts of peroxide, which leads to laboratory explosions during ether...

Sulfur Assimilation01:20

Sulfur Assimilation

553
Sulfur is an essential element in biological systems, contributing to synthesizing key biomolecules, including amino acids such as cysteine and methionine, and cofactors such as coenzyme A and biotin. Microorganisms primarily assimilate sulfur as sulfate (SO₄²⁻) from the environment, which must undergo a series of biochemical transformations before it can be incorporated into cellular components. As sulfate is highly oxidized, it must undergo assimilatory sulfate reduction to...

Area of Science:

  • Biochemistry
  • Genetics
  • Neurology

Background:

  • Methylmalonic acidemia and propionic acidemia are inherited metabolic disorders.
  • Deficiencies in methylmalonyl-CoA mutase or propionyl-CoA carboxylase lead to toxic metabolite accumulation.
  • These conditions often result in severe neurological impairment, coma, and death if untreated.

Purpose of the Study:

  • To review the role of oxidative stress and inflammation in methylmalonic acidemia and propionic acidemia.
  • To understand the oxidative stress profile in these diseases.
  • To explore new therapeutic perspectives, particularly antioxidant treatments.

Main Methods:

  • Review of findings from studies involving patients, cell models, and animal models.
  • Analysis of biochemical markers of oxidative stress and inflammation.
  • Evaluation of the impact of accumulated metabolites on cellular processes.

Main Results:

  • Accumulated metabolites in methylmalonic acidemia and propionic acidemia increase reactive species production.
  • Decreased antioxidant defenses and elevated inflammation markers are observed.
  • Oxidative damage to lipids, proteins, and DNA is evident in affected models and patients.

Conclusions:

  • Oxidative stress and inflammation are key contributors to the pathophysiology of methylmalonic acidemia and propionic acidemia.
  • These processes are implicated in the severe neurological damage associated with these disorders.
