2018, Biosensors and BioelectronicsCitation Excerpt :Based on the different polymer chain arrangement, chitin could be divided into α-, β- and γ-chitin. As shown in Fig. 4,the adjacent polysaccharide chains of α-chitin arrange in an alternating antiparallel form (Minke and Blackwell, 1978; Sikorski et al., 2009), the chains of β-chitin are arranged in parallel form (Dweltz, 1961; Cuong et al., 2016), while γ-chitin has an antiparallel and parallel structure (Jang et al., 2004). The diverse chain arrangements lead to the different mechanical properties of each chitin isomorph form (Casteleijn et al., 2018).
Bio-scaffolds produced from irradiated squid pen and crab chitosan with hydroxyapatite/β-tricalcium phosphate for bone-tissue engineering
2016, International Journal of Biological MacromoleculesCitation Excerpt :The main source of α-chitin or chitosan are shrimp and crab shells, which are produced at an industrial scale [1], while β-chitin or chitosan is obtained from squid pens [2]. Chitin or chitosan from the squid pen has a β-structure, which is loosely packed and has weak intermolecular hydrogen-bonding arrangements, compared to the tightly packed and strong molecular structure of the α-chitin or chitosan obtained from shrimp and crab shells [3–5]. Squid pen chitosan shows considerable hygroscopicity, primarily as a result of the loss of crystallinity [5].
Bio-mimetic composite scaffold from mussel shells, squid pen and crab chitosan for bone tissue engineering
2015, International Journal of Biological MacromoleculesCitation Excerpt :Chitin/chitosan from the squid pen has a β-structure that is low packed and has weak intermolecular hydrogen bonds. These properties makes it chemically more reactive compared to the heavily packed and strong molecular structure of α-chitin/chitosan from shrimp and crab shells [8–10]. In addition, β-chitin/chitosan can incorporate water molecules in its structure and forms crystalline structure leading to higher ability to uptake and hold water more than the alpha form, which is advantageous in biomedical applications [11,12].
