The Nutritional Biochemistry of Wool and Hair Follicles

The document discussed the role of various nutrients in wool and hair follicle production across different animal species. It highlighted unique features of carbohydrate metabolism in follicles, such as glutaminolysis and aerobic glycolysis, which support continuous fiber production despite nutrient fluctuations. Deficiencies in vitamins like biotin, riboflavin, pyridoxine, folate, and pantothenic acid were linked to alopecia and poor fiber growth, with folate playing a significant role in wool production. Vitamin D and A were found to influence follicle function, while copper and zinc were essential for normal keratinization and melanin synthesis. The importance of amino acids in wool growth was established, but further research was needed to understand their specific roles and transport mechanisms in follicles.
