By directly or indirectly influencing oxidation states of the L-cysteine amino acids bound up in proteins, peptides, an denzymes, many different, if not all, biochemical pathways appear to be controlled by the monooxygenase receptor for vitalethine. For example, metallothionine that protects us from toxic metals, immunoglobulins that protect us from cancer and “dys”ease, insulin, serum albumin, and a host of other peptides, proteins, and enzymes all have either high levels of L-cysteine/L-cystine in their amino acid compositions, or at critical active sites within their structures. Thus, deficiencies in protein or L-cysteine in dietary protein, can cause pathway malfunction.
