Floridean starch structure
WebNov 4, 2016 · The red alga Seirospora griffithsiana stores up to 80% of its cell volume as floridean starch. The granules are similar in structure to plant starch but more variable in size (diameter: 0.3–1.7 μm) and shape (Sheath et al., 1981). Laminarin and chrysolaminarin are the third major food reserves. WebFloridean starch ( α-1,4-glucan) is the storage polysaccharide or stored form of food found in Red algae i.e. Rhodophyceae. It is stored in the cytosol in the form of grains outside the chloroplast. Structurally, Floridean starch is very similar to amylopectin but it is more highly branched than amylopectin. So, the correct answer is B.
