Nan plant, pwodiksyon de δ-ALA se etap la sou ki vitès la nan sentèz nan klowofil réglementées. Plant yo ki manje pa ekstèn δ-ALA akimile kantite toksik nan prekursè klowofil, protochlorophyllide, ki endike ke sentèz sa a entèmedyè pa siprime nenpòt kote bès nan chèn reyaksyon an. Protochlorophyllide se yon photosensitizer fò nan plant yo.

In plants, production of δ-ALA is the step on which the speed of synthesis of chlorophyll is regulated. Plants that are fed by external δ-ALA accumulate toxic amounts of chlorophyll precursor, protochlorophyllide, indicating that the synthesis of this intermediate is not suppressed anywhere downwards in the chain of reaction. Protochlorophyllide is a strong photosensitizer in plants.
