Collagen, (acmetea) repair factor is a macromolecular functional protein. It is the main component of the skin and accounts for 80% of the dermis of the skin. It forms a fine elastic network in the skin to firmly lock moisture and support the skin.Collagen is a high molecular functional protein. It is the main component of the skin and accounts for 80% of the dermis of the skin. It forms a fine elastic network in the skin, which firmly locks in moisture and supports the skin.

Photoinitiators, also known as photosensitizers or photocuring agents, are a type of energy that can absorb certain wavelengths in the ultraviolet region (250-420nm) or visible region (400-800nm) to generate free radicals, cations, etc., thereby initiating monomer Polymerization crosslinks cured compounds.What is a photoinitiator?In the photocuring system, including UV glue, UV coating, UV ink, etc., after receiving or absorbing external energy, it undergoes chemical changes and decomposes into free radicals or cations, thereby initiating polymerization.All substances that can generate free ra

Dextran refers to a homopolysaccharide composed of glucose as a monosaccharide. The difference in the length of the dextran chain determines its different medicinal value. Long-chain dextran is usually a blood volume expansion drug with a molecular weight of tens of thousands to hundreds of thousands; while short-chain dextran can be complexed with ferric hydroxide , made of iron dextran, that is, iron dextran.What is Dextran?Dextran is a high-molecular glucose polymer synthesized from sucrose catalyzed by dextran sucrase (dextransucrase EC2.4.1.5) produced by Leuconostocmesenteroides.

Vitamin K is an essential fat-soluble nutrient, and also our body needs it to accomplish healthy and balanced blood coagulation and also other functions. It has 2 forms:Vitamin K1, (phylloquinone) is discovered in green leafy vegetables, veggies and some veggie oils.Vitamin K2, (menaquinone) exists in dairy products, fermented foods and pet products.You can likewise obtain vitamin K supplements, but scientific trials reveal that the vitamin K we extract from food is a lot more effective for our body.

In terms of market conditions, the price trend and supply - demand relationship of ammonium sulfate have always attracted much attention. Since the beginning of this year, the ammonium sulfate market has been affected by a combination of various factors. During the spring ploughing and fertilization preparation period, the overall demand in the fertilizer market has fluctuated, and ammonium sulfate, as a type of nitrogen fertilizer, has also been implicated. Domestically, its price has experienced ups and downs.

The sugar that people often eat in daily life is extracted from sugarcane, sugar beet and other plants. There are also some substances in the plant kingdom that are sweeter than sucrose. Stevia, native to South America, is 200 to 300 times sweeter than sucrose; the West African bamboo skewers in the tropical forests of Africa are 3000 times sweeter than sucrose; there is also a vine plant of Dioscorea nigra with the sweetness of the fruit. 90,000 times that of sucrose.However, these substances, which are thousands of times sweeter than sucrose, are rarely seen.

New Use of Poly-L-lactic Acid as Shape Memory MaterialBackground techniqueBiopolymer is an important medical polymer material with good biodischarge and bioabsorbability advantages. It has been widely used in outdoor fixation, tissue engineering stents, operation lines, drug control, etc. Polylactic acid is usually synthesized by the ring polymerization method of lactide. According to the difference of optical ring-opening polymerization, the lactide properties are divided into D-lactide properties, L-lactide properties and DL-lactide properties.

Niacinamide, also called nicotinamide, is an amide substance of niacin. White crystalline powder; odorless or nearly odorless, bitter in taste; slightly hygroscopic. Soluble in water or ethanol, soluble in glycerol.Because nicotinamide is a B vitamin derivative, as well as nicotinamide is additionally a component of coenzymes, it is an essential part of the body as a coenzyme of several dehydrogenases.
