Revisiting the life cycle of Margalefidinium polykrikoides Group III

Journal of Phycology, Volume 62, Issue 4, Page 1367-1382, August 2026.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

Structural features and inactivation of coagulation proteases of a sulfated polysaccharidic fraction from Caulerpa cupressoides var. lycopodium (Caulerpaceae, Chlorophyta) - doi: 10.4025/actascitechnol.v35i4.16709

Acta Scientiarum: Technology, 2013
Studies on biopolymers from macroalgae suggested sulfated polysaccharides (SPs) as research agents to investigate events related to haemostasis. Caulerpa cupressoides var. lycopodium is a marine green alga containing three SPs fractions (SP1, SP2 and SP3)

Catalytic oxidation of uronic acids to aldaric acids

, 2013
Disclosed is the oxidation of uronic acids, such as galacturonic acid, to the corresponding aldaric acids (characterized by the formula HOOC-(CHOH)n-COOH, with n being an integer of from 1 to 5) such as galactaric acids. The starting material comprising the uronic acid is subjected to oxygen under the influence of a supported gold catalyst and in the ...

The Synthesis of Nucleotide Diphosphate Uronic Acids via the Coupling of Activated Nucleotides with Uronic Acid-1-Phosphates

The Journal of Organic Chemistry
The stereoselective synthesis of nucleotide diphosphate (NDP) uronic acids from simple sugar precursors, including gluco-, galacto-, and mannopyranoside derivatives, is described. Key to this convergent synthesis is the coupling of a uronic acid 1-phosphate with a nucleotide monophosphate activated as the phosphorimidazolide to form the NDP-uronic acid,
