Lipids, Fats, and Biochemistry

A fat molecule has more carbon-hydrogen bonds than a sugar molecule. Thus, a large amount of energy can be obtained by the breakdown of fat molecules as compare to the same amount of carbohydrates. 

The external coating of a Virus is made up of proteins.

This is a right answer. Minerals are required in very small quantity from our body. Minerals are protective food and help us in keeping fit and healthy.

Fat molecules contain more carbon-hydrogen bonds per gram than carbohydrates, and each C-H bond stores significant chemical energy. This is why fats yield approximately 9 kcal/g while sugars yield only 4 kcal/g. The difference is not due to water content, animal vs plant source, or digestive waste.

Chylomicrons are lipoproteins, special particles that are designed for the transport of the dietary fats in the circulation.

Acid number or acid value refers to the number of milligrams of potassium hydroxide required to neutralize the free fatty acids in 1 g of fat.

Nervonic acid is an unsaturated fatty acid having 24 carbon atoms and 1 double bond; it is a constituent of cerebrosides.

Cellulose is the primary structural component of plant cell walls, forming a rigid network that provides mechanical support. While cell walls also contain hemicellulose, pectin, and proteins like lignin in some plants, cellulose is the dominant material. Proteins, lipids, and starch are not major wall components.

Vitamins are essential micronutrients required for various metabolic processes, but they do not provide energy when broken down. Glucose and pulses (proteins) provide 4 kcal/g, while oil (fats) provides 9 kcal/g. Only the macronutrients - carbohydrates, proteins, and fats - supply calories.

Seeds of various plants like mustard, sesame, ground nut and sunflower are used to make cooking oil. So this is the right answer.

The liver is central to the regulation of cholesterol levels in the body. Not only does it synthesize cholesterol for export to other cells, but it also removes cholesterol from the body by converting it to bile salts and putting it into the bile where it can be eliminated in the feces.

These are fat cells. They are oval or rounded cells filled with fat droplets. This tissue is found below the skin and in the bone marrow. The function of this tissue is to store fat and conserve body heat.

Amino acids are the molecular building blocks that link together to form proteins through peptide bonds. When we eat protein-rich foods, our bodies break them down into amino acids for absorption and use. Carbohydrates, fats, and vitamins are important nutrients but do not contain amino acids.
