Question

lipids

1. how are lipids defined? in what type of solvent are they soluble or insoluble? what are their functions in the body?

Explanation:

Lipids are organic compounds. They are non - polar, so they are soluble in non - polar solvents (like ether, chloroform) and insoluble in polar solvents (like water). In the body, they have functions such as energy storage (e.g., triglycerides store energy), structural components (phospholipids are in cell membranes), and as signaling molecules (e.g., steroid hormones like estrogen and testosterone).

Answer:

Lipids are organic compounds. Soluble in non - polar solvents, insoluble in polar solvents. Functions: energy storage, structural components, signaling molecules.
