(2000) constataram sua presenca em 23 especies de diferentes filos, em que o glicosaminoglicano HS mostrou-se presente para todas as especies analisadas, o CS ausente em apenas tres especies e o DS presente somente no filo Urochordata. Os pesquisadores tambem observaram distintos padroes de migracao eletroforetica de HSs extraidos de diferentes organismos aquaticos (crustaceos, nematoides, cnidarios e rotiferos), sugerindo uma possivel diferenca estrutural entre os GAGs avaliados e que eles poderiam estar envolvidos com a adesao e reconhecimento celular.
