Question

lipids are a diverse group of biological macromolecules that include triglycerides, phospholipids, waxes, and steroids. the structure of each type of lipid impacts its function. determine whether each statement is true or false. a gram of protein supplies more energy than a gram of fat. lipids are mostly hydrophobic. the structure of a lipid impacts its properties.

Explanation:

1. Lipids have non - polar regions, making them hydrophobic.
2. The structure of a lipid, such as the length of fatty acid chains, affects its properties like melting point.
3. A gram of fat supplies more energy (9 kcal/g) than a gram of protein (4 kcal/g).

Answer:

The first statement "Lipids are mostly hydrophobic" is True.
The second statement "The structure of a lipid impacts its properties" is True.
The third statement "A gram of protein supplies more energy than a gram of fat" is False.
