What do sugars and starch have in common?

Question

Also, what is the role of each of the following:
proteins, lipids, carbohydrates, and nucleic acids

Answer 1

starch is made from sugars. they are both carbohydrates.
proteins build tissues, made from amino acids
lipids are fats, used for energy
carbohydrates are used for energy
nucleic acids are in the nucleus and make DNA, to direct all the processes including reproduction where DNA carries all the info

Answer 2

Sugars form polymers to form long chains, one of which is starch. Proteins function in many ways, some of which are structure and enzymes. Lipids assemble and are present in cell membranes (mainly phospholipids), as well as provide a source of storable energy. Carbohydrates are also an energy source, usually stored in the liver when in excess. Nucleic acids contribute to DNA and the different types of RNA.

Answer 3

ENERGY SOURCE

Proteins- used to build onto the body
Lipids- fats and waxes, minor energy source
Carbs- Major energy source
Nucleic acids- DNA info

Answer 4

they are starch
proteins are needed in the diet for growth

Answer 5

carbs
