Answer:
All carbohydrates have the general formula Cn(H2O)n
Explanation:
The basic unit of carbohydrates-monosaccharides have the formula C
nH
2nO
n while the basic general formula of carbohydrates is Cm(H2O)n .
Monosaccharides are basic units (components) of carbohydrates. Those are simple sugars such as glucose, fructose, galactose. Two monosaccharides can join together via glycosylic bond and make disaccharides. Some of the disaccharides are: sucrose (glucose + fructose), lactose (galactose + glucose), maltose (glucose + glucose).
Disaccharides can be broken down to monosaccharides by an enzyme called a disaccharidase.
Longer chains of monosaccharides form oligosaccharides (usually as glycolipids ) and polysaccharides (starch, glycogen,cellulose, chitin).
Carbohyrates are important biomolecules included in metabolism, energy storage, they are also structural components, have role in immune response, as coenzymes etc.
Answer:
Edrophonium is a drug used for the treatment of myasthenia gravis, a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness, which results from antibodies that block or destroy nicotinic receptors at the junction between the nerve and muscle. By blocking cholinesterase, an enzyme which demolish acetylcholine, it increases the amount of acetylcholine in the neuromuscular junction improving the muscle weakness
