(a)

Interpretation Introduction

Interpretation:

Among A, B and C food that are high in unsaturated triacylglycerols have to be identified.

Concept Introduction:

Triacylglycerols are lipids that are formed by two or more similar or different fatty acids. They are also called triglycerides and are hydrophobic and nonpolar in nature.

Unsaturated fats are considered as healthy fats and have double bonds present in their structure. They are liquid at room temperature. For example, canola, nuts, olive oils, and vegetable oils.

(a)

Expert Solution

Explanation of Solution

Food B is high in unsaturated triacylglycerols because unsaturated fats are considered as healthy fats and are consumed as a part of healthy diet. It reduces the risk of health issues such as blood pressure, heart attack, and cholesterol. Food B has high nutritious value, therefore, food B are rich in unsaturated triacylglycerols.

(b)

Interpretation Introduction

Interpretation:

Among A, B and C food that are high in saturated fat has to be identified.

Concept Introduction:

Fats with no double bond between the molecules and are solid at room temperature are called saturated fats. They are harmful for the body. For example, dairy products such as butter, cheese, ice-cream and various oils like coconut oil and cocoa butter.

(b)

Expert Solution
Check Mark

Explanation of Solution

Food C that is cheese is high in saturated fat because consumption of excess of it increases the risk of cardiovascular diseases like high cholesterol or blood pressure in the body that in turn leads to heart stroke.

(c)

Interpretation Introduction

Interpretation:

Among A, B and C the food that contain trans fat has to be determined.

Concept Introduction:

Trans fat is similar to saturated fat formed by the partial hydrogenation of liquid oils to give semi-solid triacylglycerols. They level up the amount of bad cholesterol in blood that increases the risk of coronary diseases. Trans fat contains double bond in trans configuration. Examples are crackers, pies, and muffins.

(c)

Expert Solution
Check Mark

Explanation of Solution

Food A has high content of trans fat as similar to saturated fats. They also increase the risk of high cholesterol content in the body that leads to heart attack and is unhealthy to include in diet.
