Erythromycin, chloramphenicol, and clindamycin are all called “mycins”. What are the differences in their effects?There are many drugs with the word “mycin”, such as erythromycin, chloramphenicol, clindamycin, gentamicin, etc. are very common. So, how should these “mycins” be distinguished?
Pectin is a sort of all-natural polymer substance, which generally exists in all greater plants as well as is an important component of plant intercellular compound. Pectin is transferred in the key cell wall as well as intercellular layer, and cross-links with various components of cellulose, hemicellulose, lignin microfibrils as well as some extensin in the primary wall to make various cell cells frameworks Difficult, exhibiting an intrinsic shape, and also a supporting material for internal cells.
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.
