WebIn a lipid, there may be 1, 2 or 3 fatty acids combined with glycerol. Fatty acids 1, 2 and 3 may be the same, or different. Lipid molecules are too large to pass through the gut wall and must be ... WebAll carbohydrates are formed from the elements carbon (C), hydrogen (H) and oxygen (O). The formula of a carbohydrate is always (CH 2 O) n. The n represents the number of times the basic CH 2 O unit is repeated, e.g. where n = 6 the molecular formula is C 6 H 12 O 6. This is the formula shared by glucose and other simple sugars like fructose.

WebCorrect answer: N-glycosidic. Explanation: A glycosidic bond covalently joins a carbohydrate molecule to another molecule. An O-glycosidic bond is a covalent linkage between a carbohydrate and a protein, joining a serine or threonine hydroxyl side chain and a sugar (oxygen in the bond yields "O"). An N-glycosidic linkage involves bonding of a ... WebWhat chemical elements does a carbohydrate contain? a hexose (6 carbon) sugar, has formula C6H12O6,its atoms form a ring. State the difference between an alpha glucose molecule and a beta glucose molecule. An alpha glucose has the hydroxyl group below carbon-1, whereas a beta glucose has the hydroxyl group above carbon-1.

Carbohydrates provide energy to the … Web1 day ago · Carbon's importance comes mainly from the enormous variety of structures that it can form due to its unusual four valence electrons. Most important of these structures is the carbon chain, which forms the "backbone" of fatty acids and carbohydrates, among other organic molecules. Other elements do share properties similar to carbon, in this regard.
WebMar 5, 2024 · Monosaccharides and Disaccharides. A monosaccharide is a simple sugar such as fructose or glucose. Fructose is found in fruits, whereas glucose generally results from the digestion of other carbohydrates. Glucose(C 6 H 12 O 6) is used for energy by the cells of most organisms, and is a product ofphotosynthesis.. The general formula for a …
