CNS Depressants: Alcohol and Nicotine

CNS Depressants: Alcohol and Nicotine

Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Alcohols from Carbonyl Compounds: Grignard Reaction

Alcohols from Carbonyl Compounds: Grignard Reaction

Grignard reagents are one of the most commonly used reagents used to synthesize alcohols from carbonyl compounds. Grignard reagents are organomagnesium halides with a highly polar carbon–magnesium bond. Due to the partial ionic nature of the C–Mg bond, the carbon functions as a strong nucleophile and attacks electrophiles like carbonyl carbon.
Magnesium from the reagent coordinates with carbonyl oxygen, further reducing the carbonyl carbon's electron density. Thus, the...

Acidity and Basicity of Alcohols and Phenols

Acidity and Basicity of Alcohols and Phenols

Like water, alcohols are weak acids and bases. This is attributed to the polarization of the O–H bond making the hydrogen partially positive. Moreover, the electron pairs on the oxygen atom of alcohol make it both basic and nucleophilic. Protonation of an alcohol converts hydroxide, a poor leaving group, into water—a good one. The two acid–base equilibria corresponding to ethanol are depicted below.

Conditioned Taste Aversion

Conditioned Taste Aversion

Conditioned taste aversion, also known as sauce béarnaise syndrome, is a phenomenon in which an individual develops an aversion to a certain food taste following a negative experience, typically illness. This form of aversion is a type of classical conditioning in which the taste of the food (conditioned stimulus, CS) is associated with the experience of illness (unconditioned stimulus, UCS).
A notable characteristic of conditioned taste aversion is that it often requires only a single...

Oxidation of Alcohols

Oxidation of Alcohols

In this lesson, the oxidation of alcohols is discussed in depth. The various reagents used for oxidation of primary and secondary alcohols are detailed, and their mechanism of action is provided.
The process of oxidation in a chemical reaction is observed in any of the three forms:

Acid Halides to Alcohols: Grignard Reaction

Acid Halides to Alcohols: Grignard Reaction

Organomagnesium halides, commonly known as Grignard reagents, convert acid halides to tertiary alcohols. The reaction requires two equivalents of the Grignard reagent and proceeds via a ketone intermediate.
Grignard reagents are a source of carbanions and function as nucleophiles. The mechanism begins with the nucleophilic attack by the carbanion at the carbonyl carbon of the acid halide to form a tetrahedral intermediate. Next, the carbonyl group is re-formed, and the halide ion departs,...

Area of Science:

Psychology
Neuroscience
Toxicology

Background:

Alcohol intoxication is linked to increased risk-taking and altered emotional perception.
Theories of disgust offer a potential explanation for these alcohol-induced behavioral changes.

Purpose of the Study:

To investigate the relationship between alcohol consumption and disgust sensitivity.
To explore if disgust sensitivity mediates alcohol's effects on risk-taking behavior.

Main Methods:

A single-blind study with 73 participants randomly assigned to alcohol or placebo conditions.
Participants consumed a standardized dose of alcohol (Males: 0.68 g/kg; Females: 0.60 g/kg) or placebo.
The Thiel Disgust Scale (TDDS) was used to measure disgust sensitivity.

Main Results:

A non-significant trend indicated lower disgust sensitivity in the alcohol group compared to the placebo group.
A significant negative correlation was found between breath alcohol level and pathogen disgust sensitivity.
Higher breath alcohol levels were associated with decreased sensitivity to pathogen-related disgust.

Conclusions:

Alcohol consumption is associated with reduced disgust sensitivity.
The relationship between alcohol and disgust sensitivity, particularly for pathogen-related stimuli, may help explain alcohol-related increases in risk-taking behavior.
