Chemical composition agar mainly consists of two polysaccharides: agarose (agarose), containing about 0.14%; agar pectin (agaropectin), containing about 0.6%. In addition, also contains taurine (taurine) N,N-dimethyl taurine (N,N-dimethyltaurine), choline, vitamin B2 and 24-dimethyl cholesterol (chali-nasterol, 24-methylene cholesterol). The molecular weight of agarose is 120,000, rich in viscosity, it is a long-chain neutral compound consisting of β-D-galactose (Ⅰ) and 3,6-anhydro-α-L-galactose (Ⅱ) interactively linked, the end of the chain is D-galactose and 3,6-anhydro-L-galactose, respectively; it is hydrolyzed by acid to obtain agarobiose, and enzymatically hydrolyzed to obtain neoagarobiose. neoagarobiose) agar pectin molecular weight of 12,600, poor viscosity, containing 9 d-galactose and 1 l-lactose and 1 l-galactose sulfate composed of a unit of polysaccharides; also contains glucuronic acid and pyruvic acid. CHEMICAL IDENTIFICATION (1) Immersed in iodine solution for a few moments, it turns purplish red. (2) With 10% sodium hydroxide test solution **** heat, become yellow. (3) Add dilute hydrochloric acid **** cooking, so that the hydrolysis, add sodium hydroxide test solution and Ferrin's reagent, showing the reduction of sugar reaction (due to the generation of lactose production); such as the addition of barium chloride test solution, the generation of white precipitate. (show hydrolyzed to produce SO2-4) primary form agaric, algal body lying flat, the surface of more purplish red or yellow-green, in summer, the back of the algal body is often yellow, the ventral surface is red. Cartilaginous, irregular and branching. Branches flattened, 3-5 mm wide, 1-2 mm thick. Sometimes one side of the algal body often has a conical protuberance, both margins are densely pinnate branchlets, the tip of the branch often has a disc-shaped fixator, more in the ventral surface of the algal body, used to attach to the broken coral or other substrates. Branches and branches are often attached to each other, forming a mass. Internal structure: the outermost 3 to 4 layers of pigmented, small individual cortical cells, inward for the thin-walled cells of the pith, the pith center has dense filaments. Cyst fruit globular protruding from the surface of the alga. The tetrasporangium is divided into layers and is located in the cortex. The cystic fruit matures in June to August. It is found on broken coral near and 1-2 meters below the large dry tide line, and a few are found in shady rock crevices in the low tide zone.
