15 Σεπ 2022 · Explain how the fatty acid composition of the triglycerides determines whether a substance is a fat or oil. Describe the importance of key reactions of triglycerides, such as hydrolysis, hydrogenation, and oxidation. Fats and oils are the most abundant lipids in nature.
20 Σεπ 2024 · A lipid is any of various organic compounds that are insoluble in water. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.
No single formula can be written to represent the naturally occurring fats and oils because they are highly complex mixtures of triglycerides in which many different fatty acids are represented. The table below shows the fatty acid compositions of some common fats and oils.
10 Αυγ 2022 · Recognize the structures of common fatty acids. Describe the structure of fats and oils and classify them as saturated, monounsaturated, or polyunsaturated. Fats and oils, found in many of the foods we eat, belong to a class of biomolecules known as lipids.
Fatty acids are long, straight chain carboxylic acids. A fat (or oil) is formed when three fatty acid molecules react with a glycerol molecule to yield a triglyceride (and three water molecules). (See Figure 1.) Fats in the body are transported and stored as triglycerides.
Introduction to lipids, their molecular structure, types, and functions.
8 Φεβ 2022 · A fat molecule's three long chains of carbon and hydrogen atoms repel water, stash energy and keep living things warm — even in the bitter cold.
