Which fat has only single bonds between the carbon atoms in the fatty acid? a. saturated b. unsaturated c. polyunsaturated d. monounsaturated

Saturated fat.

Further explanationFats are naturally a group of chemical compounds that contain fatty acids.  Fats molecules consist merely of primarily carbon and hydrogen atoms.  Fats naturally provide energy, insulation, and storage of fatty acids.  Energy is gathered in the body mostly in the form of fat.  Fats may be saturated which contains single bonds, or unsaturated which has double bonds.  

Saturated fatty acids

The fatty acid is said to be saturated if there are only single bonds between the carbons atoms. As a result, the carbon atoms are bonded to as many hydrogen atoms as possible. In other words, the carbon atoms are saturated with hydrogens since single bonds increase the number of hydrogens on each carbon.  Saturated fats come from animals and some plants.Saturated fats are usually solid at room temperature.  Examples of saturated fatty acids are palmitic acid CH₃(CH₂)₁₄COOH, stearic acid CH₃(CH₂)₁₆COOH, myristic acid CH₃(CH₂)₁₂COOH

Unsaturated fatty acids

The fatty acid is said to be unsaturated if there is at least one double bond between carbon atoms. As a result,  the chain has fewer hydrogen atoms.  They are unsaturated with hydrogens.  

There are two types of unsaturated fatty acids, i.e., monounsaturated fat and polyunsaturated fat. They're found primarily in oils from plants.

monounsaturated fat is the fatty acid with only one double bond, e.g., oleic acid (C₁₈H₃₄O₂) as the main fatty acid in olive oil and canola oil.polyunsaturated fat is the fatty acid with more than one double bond, e.g., omega 3, linoleic acid (CH₃(CH₂)₄CH=CHCH₂CH=CH(CH₂)₇COOH) as the most abundant polyunsaturated fatty acid in olive oil and canola oil.

Note:

Palmitic acid is found in palm oil but also butter, cheese, milk, and meat.Stearic acid is useful as an ingredient for making candles, soaps, cosmetics and for softening the rubber.The composition of unsaturated fatty acids in olive oil and canola oil is greater than saturated fatty acids. The content of unsaturated fatty acids in both oils can reach 90%.Omega 3 is found in certain fish such as mackerel, salmon, seabass, oysters, sardines, shrimp, trout, and also in some vegetable foods such as seaweed and algae, flax seeds, hemp seeds, walnut, edamame, kidney beans, and soybean oil.Learn moreComparing the structure of fatty acids to the basic units found in other macromolecules Explaining the difference between essential body fat and storage body fat Explaining what essential fat is and describe the gender differences in fat distribution
