Standard Gibbs Free Energy of Change Formation (ΔfG in kcal/mol): 340.34763 Inferred by computational analysis [Latendresse13]

Reactions known to consume the compound:

bacteriochlorophyll a biosynthesis :
3-vinyl-bacteriochlorophyllide a + ADP + an oxidized electron acceptor + phosphate ← chlorophyllide a + ATP + a reduced electron acceptor + H2O
chlorophyllide a + H2O → 3-hydroxyethylchlorophyllide a

chlorophyll a biosynthesis II :
chlorophyllide a + geranylgeranyl diphosphate + H+ → geranylgeranyl-chlorophyll a + diphosphate

chlorophyll a degradation I , chlorophyll a degradation III :
chlorophyllide a + 3 H+ → pheophorbide a + Mg2+

chlorophyll cycle :
chlorophyllide a + NADPH + 2 H+ + oxygen → 71-hydroxychlorophyllide a + NADP+ + H2O

Not in pathways:
chlorophyllide a + 2 NADPH + 2 oxygen + 3 H+ → chlorophyllide b + 2 NADP+ + 3 H2O

Reactions known to produce the compound:

chlorophyll a degradation I , chlorophyll a degradation III :
chlorophyll a + H2O → chlorophyllide a + phytol + H+

chlorophyllide a biosynthesis I (aerobic, light-dependent) :
chlorophyllide a + NADP+ ← protochlorophyllide a + NADPH + H+

chlorophyllide a biosynthesis II (anaerobic) , chlorophyllide a biosynthesis III (aerobic, light independent) :
chlorophyllide a + an oxidized ferredoxin + 2 ADP + 2 phosphate ← protochlorophyllide a + a reduced ferredoxin + 2 ATP + 2 H2O

Not in pathways:
a chlorophyll + H2O → a chlorophyllide + phytol

Reactions known to both consume and produce the compound:

chlorophyll a biosynthesis I , chlorophyll cycle :
chlorophyllide a + phytyl diphosphate + H+ ↔ chlorophyll a + diphosphate

In Reactions of unknown directionality:

Not in pathways:
chlorophyllide a + NADP+ = divinylchlorophyllide a + NADPH + H+
