Examples of biological macromolecules that depend on hydrogen bonding include proteins, nucleic acids, and polysaccharides. Hydrogen bonding plays a crucial role in numerous chemical processes and helps define the three-dimensional structure of folded proteins, which consist of enzymes and antibodies.
Answer:
The correct choice is A............
Answer: Amino acids enter the body using a Sodium cotransporter, employing a mechanism similar to that of monosaccharides.
Explanation: Amino acids are taken up via a Sodium cotransporter, akin to the absorption of monosaccharides. Once absorbed, they cross the alabaster membrane through facilitated diffusion. Di- and tripeptides utilize distinct H+ dependent cotransporters, and upon entering the cell, they are hydrolyzed into amino acids.
Answer: starch
Explanation:
Starch, a carbohydrate, is produced by plants and is primarily found in seeds and tubers.
Starch is also used to treat cotton shirts, as it forms glycosidic bonds which contribute to the fabric's quality.
This compound consists of amylose and 70%–90% amylopectin. Amylose, a polysaccharide, comprises D-glucose monomers linked by the α-1,4-glycosidic bond, forming a helical structure with six glucose units per full turn.
Amylopectin, another polysaccharide, features glucose molecules primarily linked through α-1,4-glycosidic bonds, with occasional branching due to α-1,6-glycosidic connections. Each amylopectin molecule can have many thousands of glucose segments, with branches occurring roughly every 25 to 30 units.
