monosaccharides are the building blocks of carbohydrates. they may be found alone or combined with other molecules in fruits, vegetables, dairy products, and grains. the model shows the chemical structures of three monosaccharides: glucose, fructose, and galactose. compare glucose, fructose, and galactose. has 12 hydrogen and 6 oxygen atoms is a monosaccharide has a 6 - atom ring

monosaccharides are the building blocks of carbohydrates. they may be found alone or combined with other molecules in fruits, vegetables, dairy products, and grains. the model shows the chemical structures of three monosaccharides: glucose, fructose, and galactose. compare glucose, fructose, and galactose. has 12 hydrogen and 6 oxygen atoms is a monosaccharide has a 6 - atom ring

Answer

Brief Explanations:

  1. All three - glucose, fructose, and galactose have the chemical formula $C_{6}H_{12}O_{6}$, so they all have 12 hydrogen and 6 oxygen atoms.
  2. As stated in the text, monosaccharides are the building - blocks of carbohydrates and glucose, fructose, and galactose are examples of monosaccharides.
  3. Glucose and galactose have a 6 - atom ring structure, while fructose has a 5 - atom ring structure.

Answer:

glucose fructose galactose
has 12 hydrogen and 6 oxygen atoms √ √ √
is a monosaccharide √ √ √
has a 6 - atom ring √ × √
