Ulva conglobata

Ulva conglobata is a species of seaweed in Ulvaceae family that can be found on Jeju Island of Korea,[1] Qingdao province of China[2] and Yokohama, Japan.[3]


It is 10 centimetres (3.9 in) in length with rounded edges that are 9–16 micrometres (0.00035–0.00063 in) long and are 7–12 micrometres (0.00028–0.00047 in) wide. Its base is made up of 2 lines of cells which are 50 centimetres (20 in) in length. Its sides are 34–39 micrometres (0.0013–0.0015 in) while the bottom is 38–50 micrometres (0.0015–0.0020 in).[4]


Its methanol extract is used to cure Alzheimer's disease[5] while its ethanol have polysaccharides which contains 23.04-35.20% of sulfate ester with 10.82-14.91% of uronic acid, and 3.82-451% of protein.[2] It also produces crude enzyme when its mixed with linoleic acid[6] which is widely used to fight influenza.[7]
