Name: Chitosan

Product Overview

Chitosan is a natural polymer polysaccharide obtained by deacetylation of chitin, which has many unique properties and a wide range of applications. The molecular structure of chitosan is a linear polymer consisting of β-(1¡ãC)-2-amino-2-deoxy-D-glucose units linked by glycosidic bonds. The molecule contains a large number of amino (-NH¡ãC and hydroxyl (-OH) groups, and these functional groups give chitosan many special properties such as reactivity, hydrophilicity, biocompatibility, and so on. Compared with chitosan, chitosan has better water solubility and bioactivity due to the partial removal of acetyl group and increased amino group content, which makes it more active in chemical properties.

Chemical name: Polyglucosamine (1 - 4)-2 - amino -β -D - glucose

Molecular formula: (C6H11NO4)n

Solubility: Chitosan is insoluble in water and alkali solutions, but can be dissolved in dilute acid solutions, such as hydrochloric acid, acetic acid, etc., to form a viscous colloidal solution.

Technical Parameter

Quality at affordable prices.
Size: 11.5, Color: British Tan/Ivory
Best old guy shoes. They look great and have support for feet. You don't want cheap department shoes. You will pay for that in your later years.

Classic Craftsmanship That Keeps Perfect Time
This is an outstanding watch that blends craftsmanship, reliability, and timeless design. From the moment you put it on, it feels solid and well-built, with a level of precision that reflects true attention to detail. One important thing to understand is that this is a mechanical watch, not automatic, which means it requires manual winding. Personally, I wind the crown every morning—it’s become part of my daily routine and adds a certain charm and connection to the watch that you simply don’t get with battery-powered or automatic models. Once fully wound, the power reserve lasts around 24 hours, and impressively, the watch keeps extremely accurate time throughout. I’ve found it to be consistently reliable, rarely needing any adjustment. Rather than being an inconvenience, the manual winding becomes part of the experience—it’s a reminder of the craftsmanship behind the piece. If you appreciate traditional watchmaking and don’t mind a small daily ritual, this watch is truly exceptional.
