The model described by Naden et al. follows a two-phase process for simulating DOC concentrations at a catchment outlet:
Detail the used in Naden's DOC production module. Naden - Sulfur
: In prebiotic chemistry, sulfur biomolecules like cysteine , taurine , and methionine can be produced through atmospheric organic haze chemistry independent of biological life . The model described by Naden et al
: Sulfur is essential in the biosynthesis of metabolic cofactors like NAD+ . For example, Quinolinate synthetase (NadA) is an iron–sulfur enzyme critical to these biological pathways. sulfur biomolecules like cysteine
