Seaweeds are classified into three main groups based on their pigmentation and other characteristics, as red (Rhodophyceae
), brown (Phaeophyceae), and green (Chlorophyceae) (Chapman & Chapman, 1980), being this last group the one with the closest relationship to higher plants (Roesijadi et al., 2010).

Recently, SPs isolated from Brazilian samples of Gracilaria birdiae (Gracilariales, Rhodophyceae
) exerted in vitro inhibitory potential on a chromogenic TG assay in diluted human plasma (Rodrigues et al., 2017a).
On the basis of pigmentation they have been classified into three subgroups: i) brown seaweed (Phaeophyceae); ii) red seaweed (Rhodophyceae
) and iii) green seaweed (Chlorophyceae).
Carrageenan (CG) is a naturally occurring anionic sulphated polysaccharide extracted in 1837 from red seaweed of Rhodophyceae
family, predominantly from Chondrus crispus, Eucheuma, Gigartina stellata, Iridaea, Hypnea, Solieria, Agardhiella, and Sarconema [12-14].

Although also occurring in other living organisms (Aquino, Landeira-Fernandez, Valente, Andrade, & Mourao, 2005; Dantas-Santos et al., 2012; Chang, Lur, Lu, & Cheng, 2013), sulfated galactans (mainly carrageenan and agar) (Rhodophyceae
) (Estevez et al., 2008; Mourao, 2015), fucan or fuicodan (Phaeophyceae) (Leite et al., 1998; Pereira & Costa-Lotufo, 2012) and other structurally diverse SPs found in Chlorophyceae (Rodrigues et al., 2013; Rodrigues et al., 2014) are the main classes of these biomolecules present in nature.
