Energy-releasing Steps of Glycolysis01:28

Energy-releasing Steps of Glycolysis

146.5K
Glycolysis is divided into two phases based on whether energy is utilized or released. While the first phase consumes ATP, the second phase produces energy in the form of ATP and NADH. The energy is released over a sequence of reactions that turns G3P into pyruvate. The energy-releasing phase—steps 6-10 of glycolysis—occurs twice, once for each of the two 3-carbon sugars produced during steps 1-5 of the first phase.
The first energy-releasing step—the 6th step of glycolysis...

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

The Citric Acid Cycle02:36

The Citric Acid Cycle

161.8K
The citric acid cycle, also known as the Krebs cycle or TCA cycle, consists of several energy-generating reactions that yield one ATP molecule, three NADH molecules, one FADH2 molecule, and two CO2 molecules.

Acids, Bases and Neutralization Reactions

63.7K
An acid-base reaction is one in which a hydrogen ion, H+, is transferred from one chemical species to another. Such reactions are of central importance to numerous natural and technological processes, ranging from the chemical transformations within cells or lakes and oceans to the industrial-scale production of fertilizers, pharmaceuticals, and other substances essential to the society.

Amino acids03:42

Amino acids

104.8K
Amino acids are the monomers that comprise proteins. Each amino acid has the same fundamental structure, which consists of a central carbon atom, or the alpha (α) carbon, bonded to an amino group (NH2), a carboxyl group (COOH), and to a hydrogen atom. Every amino acid also has another atom or group of atoms bonded to the central atom known as the R group. There are 20 common amino acids present in proteins, each with a different R group. Variation in the amino acid sequence is responsible for...

Mixtures of Acids03:27

Mixtures of Acids

21.6K
The pH of a solution containing an acid can be determined using its acid dissociation constant and its initial concentration. If a solution contains two different acids, then its pH can be determined using one of several methods depending upon the relative strength of the acids and their dissociation constants.
A Mixture of a Strong Acid and a Weak Acid
In a mixture of a strong acid and a weak acid, the strong acid dissociates completely and becomes a source of almost all the hydronium ions...

Summary

Formaldehyde was detected in 24% of tested baby wipes using the chromotropic acid method (CAM). This common preservative and allergen may be an undeclared ingredient in many popular baby wipe products.

Area of Science:

  • Dermatology
  • Allergology
  • Consumer Product Safety

Background:

  • Formaldehyde is a widely used preservative known for its sensitizing properties.
  • Many consumer products, including baby wipes, may contain formaldehyde or formaldehyde-releasing agents.
  • The presence of undeclared formaldehyde in baby wipes is a potential concern for sensitive individuals.

Purpose of the Study:

  • To quantify formaldehyde release from popular baby and toddler wet wipes.
  • To assess the efficacy of the chromotropic acid method (CAM) for detecting formaldehyde in wet wipes.
  • To inform consumers and healthcare professionals about potential formaldehyde exposure from baby wipes.

Main Methods:

  • An online search identified best-selling baby wipes; none listed formaldehyde or releasers.
  • The chromotropic acid method (CAM) was employed, exposing wipes to a chromotropic acid and sulfuric acid solution.
  • Samples were incubated for 48 hours, and color change was assessed by a blinded investigator for formaldehyde presence and intensity.

Main Results:

  • Out of 51 tested baby and toddler wet wipes, 12 (24%) released formaldehyde.
  • Formaldehyde release was categorized as mild (8 wipes) or moderate/strong (4 wipes).
  • Testing yielded indeterminate results for 9 wipes (18%) and negative results for 30 wipes (59%).

Conclusions:

  • A significant portion (24%) of baby/toddler wet wipes released formaldehyde.
  • Formaldehyde can be an undeclared ingredient in baby wipes, posing a risk to sensitive individuals.
  • Awareness among patients and clinicians regarding this potential allergen source is crucial.
