Morphology
alginate = alginic (semi-transparent) = algin + ate
The form is clearly built from an algae-related stem plus the chemical suffix '-ate', but the technical meaning 'salt of alginic acid' and the specialized use of '-ate' are likely unfamiliar to average learners.
Etymology
Alginate comes from the root alga (the same root as algae) which means 'seaweed', plus the ending -ate that shows it is a 'salt' or compound. So alginate is literally a 'seaweed salt' — a substance from seaweed that forms gels or makes foods and dressings thicker.
