Which of the following is a proteinaceous and water soluble photosynthetic pigment?

Phycocyanin is a pigment-protein complex from the light-harvesting phycobiliprotein family, along with allophycocyanin and phycoerythrin. It is an accessory pigment to chlorophyll. All phycobiliproteins are water-soluble, so they cannot exist within the membrane like carotenoids can.

Proteinaceous and water-soluble photosynthetic pigment is anthocyanin. Anthocyanins are the water-soluble red and blue pigments responsible for the color of many vegetables, fruits, and flowers.

The chlorophylls are green, fat soluble and water insoluble lipid. photosynthetic pigments.

Carotenoids are lipid compounds and are red, yellow to orange in colour. The carotenoids are of two types: carotenes and xanthophylls. The carotenes are unsaturated hydrocarbons and are orange red in colour. Xanthophylls are yellow in colour.
