Aromatic Compounds: Overview

13.1K
In general, the term ‘aromatic’ indicates a pleasant smell or fragrance from fresh flowers, freshly prepared coffee, etc. In the early history of organic chemistry, many benzene derivatives were isolated from the pleasant odor oils of the plants. For example, vanillin was isolated from the oil of vanilla, methyl salicylate from the oil of wintergreen, and cinnamaldehyde from the oil of cinnamon. They all had a pleasant odor; hence the name aromatic was given.
In 1825, Faraday isolated...

Physiology of Smell and Olfactory Pathway

11.7K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
The olfactory...

Lipids: Dietary Sources and Requirements

1.6K
Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...

Lifestyle factors play a critical role in maintaining overall health and preventing chronic diseases. Key elements, such as regular physical activity, a nutritious diet, and abstinence from smoking, can significantly enhance physical, mental, and emotional well-being while reducing the risk of several life-threatening conditions.
Benefits of Physical Activity
Physical activity, whether through structured exercise or casual activities like walking, biking, or dancing, is a cornerstone of a...

Olfaction

47.8K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Effects of Chemicals: Overview01:27

Effects of Chemicals: Overview

1.9K
Drugs, encompassing various chemical compounds from natural sources, lab synthesis, or genetic engineering, elicit different biological responses in living organisms. Some of these responses are desirable or therapeutic, while others are undesirable. The primary goal of administering a drug is to achieve a therapeutic effect, that is, to address a specific disease or health condition. Any concurrent effects outside of this therapeutic outcome are considered undesirable. These undesirable...

Area of Science:

  • Integrative Medicine
  • Pharmacology
  • Toxicology

Background:

  • Essential oils (EOs) are increasingly used as alternatives to conventional medicine.
  • Their complex composition varies, making it challenging to understand their effects on the body.
  • EOs are present in numerous consumer products, from cosmetics to insect repellents.

Purpose of the Study:

  • To review the existing research on the health benefits of EOs.
  • To investigate the adverse effects associated with EO usage.
  • To provide a balanced perspective on the positive and negative impacts of EOs on human health.

Main Methods:

  • Systematic review of published scientific literature on essential oils.
  • Analysis of studies detailing antimicrobial, antiviral, anti-inflammatory, and antioxidant properties.
  • Examination of research on psychogenic effects and adverse health outcomes.

Main Results:

  • EOs and their components demonstrate antimicrobial, antiviral, antibiotic, anti-inflammatory, and antioxidant activities.
  • Purported benefits include stress relief, depression management, and insomnia aid.
  • Adverse effects noted include endocrine disruption, such as premature thelarche in adolescents.

Conclusions:

  • Essential oils possess a range of beneficial properties, including therapeutic and psychogenic effects.
  • However, their use is associated with significant health risks, notably endocrine disruption.
  • Further research and awareness are necessary to ensure the safe and effective application of EOs.
