The polysaccharide structure of potato cell walls: Chemical fractionation.

Planta

Jarvis MC, Hall MA, Threlfall DR, Friend J.
PMID: 24302375
Planta. 1981 Jun;152(2):93-100. doi: 10.1007/BF00391179.

Cell walls of potato tubers were fractionated by successive extraction with various reagents. A slightly degraded pectic fraction with 77% galacturonic acid was extracted in hot, oxalate-citrate buffer at pH 4. A further, major pectic fraction with 38% galacturonic...

Estevez JM, Ciancia M, Cerezo AS.
PMID: 26048226
Carbohydr Polym. 2008 Sep 05;73(4):594-605. doi: 10.1016/j.carbpol.2007.12.033. Epub 2008 Jan 18.

Sulfated polysaccharides were localized in the cuticle, cortex and medulla of the gametophyte thallus, being more concentrated in the intercellular matrix than in the cell walls. During the water extraction sequence, a small percentage of galactan sulfates (5.1% of...

Bryopsis sp. from a restricted area of the rocky shore of Mar del Plata (Argentina) on the Atlantic coast was identified as Bryopsis plumosa (Hudson) C. Agardh (Bryopsidales, Chlorophyta) based on morphological characters and rbcL and tufA DNA barcodes....

Preparation of individual galactan oligomers, their prebiotic effects, and use in estimating galactan chain length in pectin-derived polysaccharides.

Carbohydrate polymers

Zheng Y, Li L, Feng Z, Wang H, Mayo KH, Zhou Y, Tai G.
PMID: 30143159
Carbohydr Polym. 2018 Nov 01;199:526-533. doi: 10.1016/j.carbpol.2018.07.048. Epub 2018 Jul 17.

Galactans exhibit many biological activities, including modulation of human gut microbiota. By optimizing hydrolysis conditions and fractionation protocols, we purified a series of galacto-oligosaccharides from potato galactan, with degrees of polymerization (DP) up to 15. These oligosaccharides were characterized...

The cell wall polysaccharides of a photosynthetic relative of apicomplexans, Chromera velia.

Journal of phycology

Tortorelli G, Pettolino F, Lai DH, Tomčala A, Bacic A, Oborník M, Lukeš J, McFadden GI.
PMID: 34491587
J Phycol. 2021 Dec;57(6):1805-1809. doi: 10.1111/jpy.13211. Epub 2021 Oct 07.

Chromerids are a group of alveolates, found in corals, that show peculiar morphological and genomic features. These organisms are evolutionary placed in-between symbiotic dinoflagellates and parasitic apicomplexans. There are two known species of chromerids: Chromera velia and Vitrella brassicaformis....

Sci Rep. 2018 Dec 03;8(1):17555. doi: 10.1038/s41598-018-35914-2.

This paper proposes a novel, flexible, low cost administration patch which could be used as a non-invasive, controlled transdermal drug delivery system. The fabricated device consists in a flexible microfiber architecture heater covered with a thermoresponsive hydrogel, namely poly(N-isopropylacrylamide),...

Chickpea, dry bean, dry pea, and lentil are prominent dietary grain legumes commonly referred to as pulses. Pulses have been a staple component of the human diet for more than 8,000 years; however, in the last 70 years they...

Carrageenans in the gametophytic and sporophytic stages of Chondrus crispus.
