The invention belongs to biomedicine technical field, be specifically related to a kind of hyaluronic acid odd number oligosaccharide monomer and preparation method thereof. Along with deepening continuously of the aspect researchs such as the domestic and international distribution to HA, chemical structure and physico-chemical property, find that HA has multiple biological function, as participated in lung and vascular disease and embryoplastic intracellular signaling, wound healings etc. HA oligosaccharides as antagonist can with CD44 receptors bind, accelerate the cracking of CD44, thus reduce drug-resistant effect, the resistance of Tumor suppression. In addition, HA oligosaccharides can promote wound healing, inducing macrophage expresses multiple chemokine. Research finds, the biomolecule action such as oligosaccharides and protein plays in the process of physiological function, and kind and its activity of the polymerization degree of oligosaccharides and reducing end or non-reducing end saccharide residue are closely related.

This page explains the terms strong and weak as applied to acids. As a part of this it defines and explains what is meant by pH, K a and pK a. We are going to use the Bronsted-Lowry definition of an acid. When an acid dissolves in water, a proton hydrogen ion is transferred to a water molecule to produce a hydroxonium ion and a negative ion depending on what acid you are starting from. These reactions are all reversible, but in some cases, the acid is so good at giving away hydrogen ions that we can think of the reaction as being one-way.

Think you can dissolve a body in an acid bath, Breaking Bad style, and get away with it? Think again says Erwin Vermeij. In the past 15 years I have seen more than most people could imagine, including a victim who was chopped up and stir-fried and another whose corpse had been fed through a wood-shredder. But 12 years ago, I was stumped when police unearthed a large, moist, off-white block in the garden of a suspected drugs trafficker.

I am to investigate the effect on the rate of reaction which can be seen when I change first the concentration of acid used and then the types of acids used.

ICSE Chemistry Question Paper 2009 Solved for Class 10

Although it sounds odd, one of the best ways to discriminate fiber specimens is by attempting to dissolve them in various solvents. For example, you may have identified a questioned fiber as artificial by the burning test, but you do not yet know what type of artificial fiber it is. By attempting to dissolve a small specimen of that fiber in each of several solvents, you can determine if it is, for example, nylon, acetate, or polyester. Solubility tests are particularly important for discriminating artificial and reconstituted fibers, because they are produced by machinery and so lack the microscopic variations characteristic of natural fibers. For example, although it is easily possible to discriminate wool or cotton from an artificial fiber microscopically, it may be impossible to determine whether an artificial fiber is acetate or polyester without performing solubility or other chemical tests. Professional forensic scientists use a wide variety of solvents for solubility tests, but many of those solvents are expensive or difficult to obtain for a home lab. Nylon dissolves, but very slowly. Rayons dissolve slowly.
