On Jellying Property of Red-algae Mucilages

Studies on Polyethers Produced by Red Algae

Two novel squalene-derived triterpenes, spirodehydrovenustatriol (3) and 14-keto-dehydrothyrsiferol (4) were isolated from the red alga Laurencia viridis, together with two new and unusual C(17) terpenoids, adejen A (5) and B (6). These truncated structures possess structural similarities with other known squalene metabolites and their biogenetic origin has been proposed on the basis of an oxid...

Red algae delays chronological ageing

During the chronological ageing process epidermal skin stem cells become less effective, meaning that the renewing and repairing activity of the epidermis is reduced. Moreover, fewer elastic fibres are synthesised, thereby inducing a progressive loss of skin elasticity. The standardised, COSMOS certified Cyanidium caldarium red algae extract, unique in its capability to produce gamma aminobutyr...

CLASSIFICATION: BIOLOGICAL SCIENCES, BIOCHEMISTRY Characterization of the hetero-oligomeric red-type rubisco activase from red algae Short title: Hetero-oligomeric rubisco activase from red algae Key words: Rubisco, activase, photosynthesis, AAA+ proteins, red algae

Antibacterial and antioxidant activities of the red algae Hypnea charoides from coasts of Chabahar

Background and objectives: Marine macro algae are one of the most economically important resources of the oceans which contain important biologically active secondary metabolites. So they can be widely used in various applications. Due to the limited research work on the bioactive metabolites from Iranian algae, the red seaweed, Hypnea charoides, collected from interti...

The origin of red algae: implications for plastid evolution.

The origin of the red algae has remained an enigma. Historically the Rhodophyta were classified first as plants and later as the most ancient eukaryotic organisms. Recent molecular studies have indicated similarities between red and green plastids, which suggest that there was a single endosymbiotic origin for these organelles in a common ancestor of the rhodophytes and green plants. Previous e...
