Question

1. what type of biological molecule is shown below? *

mark only one oval
carbohydrate
protein
lipid

Explanation:

Lipids are a diverse group of biological molecules that are insoluble in water but soluble in non - polar solvents. One common type of lipid is a phospholipid. Phospholipids have a phosphate group (the - P in the diagram) which is hydrophilic (water - loving) and fatty acid chains (the hydrocarbon chains with \(CH_2\) and \(CH_3\) groups) which are hydrophobic (water - hating). Carbohydrates typically have a formula \(C_n(H_2O)_n\) and are made up of sugar units. Proteins are made up of amino acids linked by peptide bonds. The structure shown in the diagram with a phosphate group and hydrocarbon chains is characteristic of a lipid (specifically a phospholipid).

Answer:

lipid
