Which molecule is
A lipid is a hydrophobic polymer, not a carbohydrate.
Which of the following statements about monosaccharide structure is true?
Aldoses and ketoses differ in the position of their hydroxyl groups.
A six-carbon sugar is called a pentose.
All monosaccharides contain carbon, hydrogen, oxygen, and nitrogen atoms.
Monosaccharides can be classified according to the spatial arrangement of their atoms.
This statement is true.
True or false? Peptidoglycan is a polysaccharide found only in bacteria.
Which complex carbohydrate contains only a-1,4-glycosidic linkages?
Amylose is formed from a-1,4-glycosidic linkages of glucose.
Which of the following complex carbohydrates is listed with its correct function?
Amylose: main component of plant starch
Chitin: constituent of bacterial cell walls
Starch: primary energy-storage molecule in animals
Cellulose: structural component of plant cell walls
Cellulose is indeed the main structural component of plant cells walls.
Which polysaccharide contains a modified monosaccharide?
-acetylmuramic acid units that make up peptidoglycan are composed of modified glucose monomers.
