Fatty acids and triglycerides
Fatty acids and triglycerides are the forms of lipids that is used to store energy in the body. Triglyceride is an ester which is formed when glycerol combines with three fatty acid molecules. Fatty acids are the simplest form of lipids molecules. Fat is stored in the adipose tissue and under the skin of the body

Membrane lipids have fatty acid tails and, like triacylglycerols, their properties are governed by the properties of these tails. Based on what we saw with dietary lipids, which membrane would have more fluid characteristics – the one with more saturated fatty acids or the one with more unsaturated fatty acids? Explain your reasoning. Look at the structure of cholesterol. Cholesterol is a necessary component of biological membranes. What do you think cholesterol would do to the structure of a membrane...
