orphan.products: Identifies the orphan products for a set of stoichometric reactions

Description

This function identifies the orphan products (products that are not consumed in any other reaction. Possible dead-ends) for a set of stoichometric reactions. This function assumes that all your reactions have the following format L-Glutamate[c] <=> CO2[c] + 4-Aminobutanoate[c]

Usage

orphan.products(reactionList,byCompartment)

Arguments

reactionList

A set of stoichiometric reactions

byCompartment

A logical value (TRUE/FALSE) if orphans should be reported by compartment

Examples

# Loading a set of stoichiometric reactions from the glutamate/glutamine cycle
data("glugln")

# Identifying dead-ends from a sample of 100 stoichiometric reactions
orphan.products(glugln)
# [1] "alpha-D-Glucose[r_n]"           
# [2] "phosphate(3-)[r_n]"             
# [3] "2-phospho-D-glyceric acid[r_n]"
# [4] "GDP[c_n]"                       
# ...
# [20] Ferricytochrome c2[m_a]"
