Vitamins

2.9K
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced...

Role of Vitamins in Maintaining Bone Health01:25

Role of Vitamins in Maintaining Bone Health

6.0K
The growth and maintenance of bone are regulated by a combination of nutritional factors, including vitamins, such as vitamin A, B12, C, D, and K.
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...

Role of Skin in Vitamin D Synthesis01:23

Role of Skin in Vitamin D Synthesis

8.7K
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...

Factors Affecting Illness01:18

Factors Affecting Illness

5.6K
When a person's physical, emotional, intellectual, social development or spiritual functioning is compromised, this deviation from a healthy normal state is called illness. Illness creates stress that in turn harms individuals. Irritation, anger, denial, hopelessness, and fear are behavioral and emotional changes an individual experiences in the phases of illness. A variety of factors influence a person's health and well-being.
For instance, risk factors are connected to illness,...

Bone Disorders01:29

Bone Disorders

7.3K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Immunodeficiency Diseases01:25

Immunodeficiency Diseases

2.8K
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.
There are three main causes of immunodeficiency...

    Summary

    Vitamin D deficiency is linked to polymorbidity, which involves systemic metabolic changes like lipid, mineral, and glucose metabolism disorders. This highlights vitamin D

    Area of Science:

    • Endocrinology
    • Metabolic Medicine
    • Nutritional Science

    Context:

    • Polymorbidity, the presence of multiple chronic diseases, is a growing public health concern.
    • Systemic metabolic dysregulation, including lipid, mineral, and glucose metabolism issues, is implicated in disease development.
    • The role of micronutrients in metabolic health is an area of active research.

    Purpose:

    • To review the current understanding of vitamin D's metabolic functions.
    • To explore the association between vitamin D status and the development of polymorbidity.
    • To emphasize the significance of vitamin D in maintaining overall metabolic balance.

    Summary:

    • Systemic metabolic changes, encompassing lipid, mineral, and glucose metabolism, alongside hormonal status, contribute to polymorbidity.
