Vitamins and lipid metabolism

A Fidanza, M Audisio

    Acta Vitaminologica Et Enzymologica
    |January 1, 1982
    PubMed
    Summary

    Vitamins are crucial for lipid metabolism, impacting fatty acid synthesis, oxidation, and cholesterol levels. Deficiencies may cause lipid disorders, while specific vitamins like niacin offer therapeutic benefits.

    Area of Science:

    • Biochemistry
    • Nutritional Science
    • Metabolic Research

    Background:

    • Vitamins are essential micronutrients vital for numerous metabolic processes.
    • Lipid metabolism encompasses the synthesis, transport, and breakdown of fats, crucial for energy and cellular function.
    • Disruptions in lipid metabolism are linked to various health issues, including cardiovascular diseases.

    Purpose of the Study:

    • To elucidate the role of specific vitamins (pantothenic acid, niacin, riboflavin, B12, folic acid, vitamin C) in lipid metabolism.
    • To explore the mechanisms by which these vitamins influence fatty acid synthesis, oxidation, and cholesterol regulation.
    • To investigate the potential link between hypovitaminosis and lipid metabolism disorders.

    Main Methods:

    • Review of biochemical pathways involving vitamins as coenzymes in lipid metabolism.
    • Analysis of studies on the effects of niacin and its derivatives on lipid profiles.
    • Examination of experimental data on pantothenic acid and vitamin C administration on plasma lipid fractions.

    Main Results:

    • Vitamins B (pantothenic acid, niacin, riboflavin) act as coenzymes in fatty acid synthesis and oxidation.
    • Vitamin B12 and folic acid are involved in phospholipid biosynthesis via methyl radical balance.
    • Vitamin C aids cholesterol conversion to bile acids; essential fatty acids influence cholesterol transport and reduction.
    • Niacin derivatives favorably alter HDL and LDL cholesterol levels.
    • Pantothenic acid and vitamin C administration impact plasma lipids, triglycerides, and fatty acids.

    Conclusions:

    • Vitamins are indispensable for normal lipid metabolism.
    • Hypovitaminosis is a potential cause of lipid metabolism disorders.
    • Certain vitamins, like niacin, possess therapeutic potential for managing dyslipidemia.
