Relative amounts of carotenoids in thylakoids isolated from cells grown at 25°C or 35°C and a light intensity of 100 or 400 μEm⁻²s⁻¹

Thylakoid, temperature/light	β-Carotene (neut), relative %	Echinenone, relative %	Zeaxanthin, relative %	Myxoxanthophyll, (pol.), relative %	Pol/neut (ratio)
RT35/100	32	40	2	26	1.2
RT35/400	30	43	2	25	1.2
RT25/100	16	39	2	43	2.7
RT25/400	18	40	1	41	2.8

The error in the relative amounts of carotenoids is about 15%, and that in the polar/neutral ratio (pol/neut) is about 20%. Relative amounts are calculated from the measurements listed in Table 2.
