Researchers should ensure all handling, storage and use complies with relevant laboratory guidelines and standards
That enzyme is NNMT, nicotinamide N-methyltransferase
Hydroxyproline incorporation assays measure increased collagen production rates, with procollagen ELISA protocols confirming enhanced synthesis at the molecular level
Subgroup analyses were planned based on age group (e.g., children, adults, older adults), baseline serum Vitamin B12, and the form of Vitamin B12 used
Vitamin B12 also may be involved in maintaining sulfhydryl (SH) groups in the reduced form required by many SH-activated enzyme systems
