Function
function
The light-harvesting complex (LHC) functions as a light receptor, it captures and delivers excitation energy to photosystems with which it is closely associated. Energy is transferred from the carotenoid and chlorophyll C (or B) to chlorophyll A and the photosynthetic reaction centers where it is used to synthesize ATP and reducing power.

Interaction
Subunit
The LHC complex of chromophytic algae is composed of fucoxanthin, chlorophyll A and C bound non-covalently by fucoxanthin chlorophyll proteins (FCPs). The ratio of the pigments in LHC; fucoxanthin: chlorophyll C: chlorophyll A; (0.6-1): (0.1-0.3): 1.
