Question

Complete the following passage(s) with an appropriate word/term to be filled in the blank spaces

Glycerol, Methyl, 20 Carbon, Trihydroxy propane, a Carboxyl, Insoluble, Fatty acids, 16 Carbons, Triglycerides, Lower
Lipids are generally water ..........(1)........They could be simple fatty acids. A fatty acid has ..........(2)........ group attached to an R group. The R group could be a ..........(3)........ (--CH${}_3$), or ethyl (-C${}_2$H${}_5$) or higher number of -CH${}_2$ groups (1 carbon to 19 carbons). For example, palmitic acid has ..........(4)........ including carboxyl carbon. Arachidonic acid has ..........(5)........ atoms including the carboxyl carbon. Fatty acids could be saturated (without double bond) or unsaturated (with one or more C = C double bonds). Another simple lipid is glycerol which is ..........(6):....... Many lipids have both ..........(7)........and ..........(8)........Here the fatty acids are found esterified with glycerol. They can be then monoglycerides, diglycerides and .........(9).......... These are also called fats and oils based on the melting point. Oils have ..........(10)........ melting point (e.g., gingely oil) and hence remain as oil in winters.
