Summary
Retinoids are essential for vision, immunity, and skin health, with over 500 genes regulated by retinoic acid. This review highlights recent advances in understanding complex retinoid metabolism and its dietary requirements.
Area of Science:
- Biochemistry
- Molecular Biology
- Human Physiology
Background:
- Retinoids are vital micronutrients essential for numerous physiological functions, including vision, immunity, reproduction, and skin barrier integrity.
- Retinoic acid, a key metabolite, regulates a vast network of over 500 genes.
- Dietary intake is crucial as the body cannot synthesize retinoids.
Purpose of the Study:
- To review recent advancements in understanding retinoid metabolism.
- To elucidate the complex pathways and molecular players involved in retinoid processing.
- To highlight the significance of retinoids in various biological processes.
Main Methods:
- Literature review focusing on research from the last 10-15 years.
- Analysis of studies on retinoid forms, carrier proteins, and enzymes.
- Integration of findings related to retinoid and lipid metabolism.
Main Results:
- Retinoid metabolism involves a complex interplay of various forms (retinyl esters, retinol, retinal, retinoic acid) and their metabolites.
- Specific enzymes and carrier proteins are critical for retinoid processing.
- Connections between retinoid and triglyceride/cholesterol metabolism are increasingly recognized.
Conclusions:
- Recent research has significantly advanced our understanding of retinoid metabolism.
- The complexity of retinoid pathways underscores their fundamental role in health.
- Further investigation into retinoid metabolism promises insights into various physiological and pathological conditions.

01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:28Overview of Fatty Acid Metabolism
Lipids also are sources of energy that power cellular processes. Like carbohydrates, lipids are composed of carbon, hydrogen, and oxygen, but these atoms are arranged differently. Most lipids are nonpolar and hydrophobic. Major types include fats and oils, waxes, phospholipids, and steroids.
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

01:24Overview of Lipid Metabolism
Lipid metabolism is a crucial process in the human body that involves the synthesis and degradation of lipids. This process is essential for energy production, cell membrane formation, and hormone production, among other functions.
Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...

01:23Role of Skin in Vitamin D Synthesis
The skin plays a crucial role in the synthesis of vitamin D, a vital nutrient for various physiological processes in the body. Vitamin D is unique because it can be synthesized in the skin through a series of chemical reactions triggered by exposure to ultraviolet B (UVB) radiation from sunlight.
The solar UV B rays (290-315 nm) are absorbed by the skin, and 7-dehydrocholesterol (provitamin D3) photolyzes it to previtamin D3, which undergoes a rapid transformation to vitamin D3(cholecalciferol).

01:40Overview of Metabolism
Living cells constantly carry out various chemical reactions which are necessary for their proper functioning. These reactions are interlinked to one another via multiple pathways. The collection of these chemical reactions is known as metabolism.

01:17Bioavailability: Overview
Bioavailability refers to the proportion of an administered drug that reaches the systemic circulation in its active, unaltered form. It is a crucial pharmacokinetic parameter that determines the effectiveness of a drug in achieving its intended therapeutic outcomes. The route of administration significantly influences bioavailability, with intravenous administration achieving 100% bioavailability as the drug directly enters the bloodstream. In contrast, oral administration often results in...
