Table 1.1 gives the C:D value for oleic acid. In Table 1.1, enter the values for D for each of the other four fatty acids shown.
Within the first column of Table 1.1, place a circle around every fatty acid that is saturated.
State which part of the chemical structure, labelled X, is missing from Table 1.1.
The analysis of the triglycerides in the different olive oil samples showed that: - olive oil contains many different triglycerides - the composition of each olive oil is different, but the same few triglycerides occur in all olive oils. Using Table 1.1 and the structure of triglycerides, suggest explanations for these findings.
Glycerol dissolves in water. Triglycerides do not dissolve in water. Explain why water is a good solvent for some substances such as glycerol, but a poor solvent for substances such as triglycerides.
Phloem is the plant tissue that transports organic substances, such as fatty acids, from one part of a plant to another. It consists of more than one cell type. Name the type of cell that forms the transport vessels of phloem tissue.
