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...

The Skin Microbiota01:27

The Skin Microbiota

123
The human skin serves as a complex ecosystem inhabited by a diverse community of microorganisms, including bacteria, fungi, and viruses. This microbiome plays a critical role in maintaining skin health and defending against pathogenic invaders. The composition of microbial communities varies significantly across different regions of the body, influenced primarily by the local levels of moisture and sebum.Regional Variation in Skin MicrobiotaCutibacterium acnes predominantly colonizes sebaceous...

Accessory Structures of the Skin: Sweat Glands01:20

Accessory Structures of the Skin: Sweat Glands

4.1K
Sweat glands or sudoriferous glands are one of the important accessory structures of the skin. They are small, coiled tubular structures located in the dermis, the middle layer of the skin. Sweat glands are responsible for producing and secreting sweat, a watery fluid that helps regulate body temperature and excrete waste products.
Sweat glands are classified as merocrine glands; that is, the secretions are excreted by exocytosis through a duct without affecting the cells of the gland. There...

Microbial Spoilage of Food01:23

Microbial Spoilage of Food

218
Microbial food spoilage refers to the degradation of food quality resulting from the metabolic activity of microorganisms such as bacteria, yeasts, and molds. These microbes proliferate on various food substrates depending on factors such as moisture content, nutrient availability, and storage conditions, leading to undesirable sensory and structural changes.Bacteria are primary agents of spoilage in high-moisture, nutrient-dense foods like meat, milk, and vegetables. Microbial spoilage occurs...

Surface Membrane Barriers01:18

Surface Membrane Barriers

3.0K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Olfactory Receptors: Location and Structure01:03

Olfactory Receptors: Location and Structure

10.5K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Summary
This summary is machine-generated.

Underarm odor, or bromidrosis, may stem from dietary terpenes excreted by apocrine glands. Tomatoes and lycopene-rich foods are likely culprits, suggesting a link between diet, axillary glands, and body odor.

Area of Science:

  • Biochemistry
  • Human Physiology
  • Genetics

Background:

  • Underarm odor (bromidrosis) significantly impacts social interaction and self-esteem.
  • Current management includes hygiene, antiperspirants, and deodorants, with surgery for severe cases.
  • Microbial breakdown of apocrine secretions causes odor; genetics (ABCC11 gene variants) also play a role.

Purpose of the Study:

  • To investigate alternative causes of underarm odor beyond microbial action and genetics.
  • To propose terpenes excreted by axillary apocrine glands as a common cause of bromidrosis.
  • To identify dietary sources of these terpenes and their metabolic pathways.

Main Methods:

  • Analysis of axillary apocrine gland secretions.
  • Correlation of odor compounds with dietary intake of terpenes and carotenoids.
  • Investigation of lycopene metabolism via β-carotene 9 10 monooxygenase.

Main Results:

  • Terpenes excreted via axillary apocrine glands are proposed as a significant contributor to underarm odor.
  • Dietary sources like tomatoes and lycopene are implicated.
  • Evidence suggests lycopene is metabolized by β-carotene 9 10 monooxygenase.

Conclusions:

  • Dietary terpenes, particularly from tomatoes, are a likely source of underarm odor.
  • Axillary apocrine glands serve as a key excretory route for these compounds.
  • Further analysis of axillary secretions can advance terpene and carotenoid metabolism studies.
