question 10 (2 points) saved what intermolecular force of attraction are important for tertiary structure? disulfide bridges, hydrogen bo a√ q3. a. describe the general characteristic of all fatty acids ku/2 b.compare the shape of saturated and unsaturated fatty acids provide example to support your description. ku/3 c. what functional groups are involved in the formation of triglycerides and a phospholipids. ku/2

Explanation:

a. Fatty acids are long - chain carboxylic acids. They have a carboxyl group (-COOH) at one end and a long hydrocarbon chain.
b. Saturated fatty acids have a straight shape as they have single bonds only in the hydrocarbon chain, like stearic acid. Unsaturated fatty acids have a bent shape due to the presence of double bonds, for example, oleic acid.
c. In the formation of triglycerides, the hydroxyl groups (-OH) of glycerol and the carboxyl groups (-COOH) of fatty acids are involved. In phospholipids, in addition to the above, a phosphate group and an alcohol group are also involved in the structure - forming process.

Answer:

a. Long - chain carboxylic acids with a carboxyl group and a hydrocarbon chain.
b. Saturated are straight (e.g., stearic acid), unsaturated are bent (e.g., oleic acid).
c. For triglycerides: hydroxyl of glycerol and carboxyl of fatty acids. For phospholipids: hydroxyl of glycerol, carboxyl of fatty acids, phosphate group and an alcohol group.
