Chitin (β-()-poly-N-acetyl-D-glucosamine) is widely distributed in nature and is the second most abundant polysaccharide after cellulose. It is often converted to its more deacetylated derivative, chitosan. Previously, many reports have indicated the accelerating effects of chitin, chitosan, and its derivatives on wound healing. More recently, chemically modified or nano-fibrous chitin and Cited by: Chitin is the second most abundant biopolymer found in nature next to cellulose and is derived from the exoskeletons of crustaceans, molluscs, insects, and cell walls of fungi . Chitin and chitosan are considered as useful biocompatible materials to be used in a medical device to treat, augment or replace any tissue, organ, or function of the body. nature . Chitin Chitin is a major constituent of the exoskeleton, or external skeleton, of many arthropods such as insects, spiders, and crustaceans. Exoskeletons made of this durable and firm compound support and protect the delicate soft tissues of these animals, which lack an internal skeleton.

Keep outside in mind for less stress. Spending time in nature can help relieve stress and anxiety, improve your mood, and boost feelings of happiness and wellbeing. Whatever you call it – forest bathing, ecotherapy, mindfulness in nature, green time or the wilderness cure -- humans evolved in the great outdoors, and your brain benefits from a journey back to nature. Examples of polysaccharides include starch, glycogen, cellulose and chitin. Starch tends to form in a helix, or spiral shape; this is common in high-molecular-weight biomolecules in general. Cellulose, in contrast, is linear, consisting of a long chain of glucose monomers with hydrogen bonds interspersed between carbon atoms at regular intervals.
