Summary

The purpose of our study is to investigate the effects of supplemental mannose on sera of humans who are healthy. We will perform proteomics studies to elucidate changes to glycan structure and protein level changes. We hypothesize that we may find that mannose supplies more properly glycosylated protein substrate and helps expedite protein synthesis, that excess mannose leads to alternative glycan structures which confer improved stability, or that there are new sites that become glycosylated after mannose supplementation.

Detailed description

Subjects will be enrolled and a baseline blood sample taken. Subjects will take mannose supplements for 1 week (3-4 packets of a standard dose in water), then a follow up blood sample will be taken. Subject blood will be analyzed by proteomic analysis for 1) change in glycan structure or 2) other protein based approaches to measure changes in levels of proteins.

Type	Name	Description
DIETARY_SUPPLEMENT	Mannose	Mannose is a sugar monomer that is important in the glycosylation of many proteins. The concentration of mannose in mammalian plasma is \~50-100 μM, which is primarily derived from N-glycan processing. Taking dietary mannose supplements can raise the levels of plasma mannose by 3- to 5-fold. There are currently no known adverse effects of mannose supplementation in humans.
