Prolonging healthy aging: Longevity vitamins and proteins.

Summary
Proteins are classified as survival or longevity types. Nutrient deficiencies impair longevity proteins, increasing aging disease risk. "Longevity vitamins" may mitigate this, suggesting dietary improvements or supplements for better health.
Area of Science:
- Biochemistry
- Nutrition Science
- Gerontology
Background:
- The triage theory suggests nutrient deficiencies prioritize immediate survival over long-term health.
- This prioritization mechanism may impair proteins crucial for protecting against aging-related damage.
- Impaired function of these 'longevity proteins' can accelerate age-related diseases.
Purpose of the Study:
- To propose a classification of proteins into 'survival' and 'longevity' types.
- To introduce the concept of 'longevity vitamins' essential for the function of longevity proteins.
- To review evidence for taurine as a conditional vitamin and specific compounds as potential longevity vitamins.
Main Methods:
- Literature review and theoretical proposal.
- Classification of proteins based on essentiality for survival/reproduction versus long-term health.
- Examination of nutrient-cofactor roles in protein function and health outcomes.
Main Results:
- Proteins can be functionally categorized into survival and longevity types.
- Nutrient deficiencies disproportionately affect longevity proteins, increasing aging disease risk.
- Several compounds, including ergothioneine, PQQ, queuine, and various carotenoids, are identified as potential longevity vitamins.
Conclusions:
- A novel classification of proteins and vitamins based on survival and longevity functions is proposed.
- Nutrient deficiencies are linked to accelerated aging and chronic disease risk via impaired longevity proteins.
- Dietary improvements and supplementation with 'longevity vitamins' may reduce the risk of age-related diseases and premature aging.

01:30Vitamins
2.5K
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...

Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

01:23Role of Skin in Vitamin D Synthesis
7.9K
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...

1.6K
Electrolytes are essential minerals and ions primarily obtained from the diet and absorbed through the gastrointestinal tract. Most electrolytes are absorbed in the small intestine. While the absorption of iron and calcium primarily occurs in the duodenum, calcium is also absorbed in the jejunum and ileum. In these regions, passive diffusion contributes to its absorption alongside active transport mechanisms in the duodenum. These ions can exit the enterocytes through specialized active...

01:19The Effect of Aging on Tissues
3.5K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

01:25Role of Vitamins in Maintaining Bone Health
5.5K
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...
