As we mentioned earlier, some nutrients effective to a degree in slowing cross-linking include cysteine (a sulfur-containing amino acid, which helps maintain sulfur in proteins in the reduced state); vitamins A, B-1, B-5, B-6, C, E; the mineral selenium; and other antioxidants. Removal of calcium and heavy metals from collagen by chelating agents may be […]

Proteins are complex molecules, made up of amino acids, which perform a wide variety of functions in the human body, from chemical reaction-controlling enzymes, to structural molecules like collagen, to necessary components in human memory. In order to function properly, proteins must assume a correct three-dimensional configuration. In their proper shape, some proteins act as […]
