-carbohydrates contain carbon , hydrogen and oxygen
-also known as saccharides
-glucose is a hexose monosaccharide (composed of 6 carbons )
-two structural variations: alpha α and beta β glucose ,in which the OH group on carbon 1 is in opposite positions
- glucose : polar and soluble in water due to the bonds that form between the hydroxyl groups and water molecules
-glycosidic bond : bond formed between two glucose molecules by a condensation reaction forming a disaccharide
-fructose +galactose =sucrose
-galactose +glucose = lactose
- starch :many alpha glucose molecules can be joined by glycosidic bonds to form two slightly different polysaccharides
- one of the polysaccharides of starch is called amylose
- amylose : formed by alpha glucose molecules joined together only by 1-4 glycosidic bonds
-amylopectin: both 1-4 and 1-6 (every 25 glucose subunits )glycosidic bonds between alpha glucose molecules. 1-6 glycosidic bonds cause branching
-glycogen : more branches than amylopectin . Compact so ideal for storage . Speeds up the process of storing and releasing glucose molecules required in the cell.Insoluble
-hydrolysis reactions opposite of condensation reaction
-cellulose:beta glucose molecules. Join together by alternate beta glucose molecules turn upside down
- straight chain molecule: cellulose
-cellulose molecules make H bonds with each-other forming microfibrils. Microfibrils join together to form macrofibrils which combine to produce fibres
Answer:
pseudoscience is the correct answer
Explanation:
//pseudoscience// A theory, methodology, or practice that is considered to be without scientific foundation.
The uneven heating of Earth's surface produces wind because the air temperature and air pressure are different. The differences in the air causes the air to a lower pressure. ... Uneven heating of the Earth's surface produces air masses of different temperatures. Cold air sinks, forcing warm air to rise.
Hope this helped! :D
Answer:
110 kg
Explanation:
Density = Mass / Volume ===> Mass = Density x Volume
Now follow the given:
- Density = 2 kg/L or 2000 g/L
- Volume = 55 L
Apply the rule:
Mass = 55 L x 2 kg/L = 110 kg or 110000 g. ( Liters is cancelled by Liters).
Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce
Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
