Question

Explain each term and give an example: saturated fat, unsaturated fat, monounsaturated fat, polyunsaturated fat, cis fat, trans fat Explain each term and give an example: carbohydrate, monosaccharide, disaccharide, polysaccharide What is the definition of a foodprint? How specifically might each of these affect your foodprint: eating a veggie burger instead of a hamburger, eating corn instead of a veggie burger What are the monomer units of proteins? DNA? Polysaccharides?

Answer 1

SATURATED FAT: This type of fat contains fatty acids which are saturated ( ie; the molecule does not contain double bonds in it). They are solid at room temperature. example: stearic acid, palmitic acid. Food sources containing saturated fat: butter, cheese

UNSATURATED FAT : This type of fat contains fatty acid molecules which are unsaturated (ie: these compounds contains one or more double bonds in it ). They usually exist as liquid at room temperature. example: oleic acid, linolenic acid. Food sources containing unsaturated fat : vegetable oils such as sunflower , canola.

MONOUNSATURATED FAT: These fatty acid molecules contain only one double acid in them while all other carbon atoms are bonded to each other by means of single bond. example: Oleic acid  Food sources containing monounsaturated fat: olive oil, sesame oil

POLYUNSATURATED FAT: These type of fatty acid molecules contain more than one double bond in them ( ie these compounds have atleast  two carbon-carbon double bond or more than that.) example:Linoleic acid Food sources containing polyunsaturated fat :nuts, fishes

CARBOHYDRATES: Carbohydrates are organic compounds that contain carbon, hydrogen and oxygen atoma. These commonly include starch, sugar and cellulose. They can be broken down into simpler compounds and release energy in human and animals. Examples of carbohydrates include: glucose, fructose. Food sources containing carbohydrates are milk , rice

MONOSACCHARIDE: They are the simplest form of carbohydrates which cannot be broken down further. They are joined or grouped together to form disaccaride and polysaccharide. example: glucose, fructose, galactose  Food sources containing monosaccharides are honey and cane sugar

DISACCHARIDE: These are carbohydrates molecules that contain two monosaccharides in them. The two monosaccharide molecules are bonded by glycosidic bond. Example: sucrose, lactose, maltose.  Food sources containing disaccharides are cheese, butter, yogurt

POLYSACCHARIDE: These complex carbohydrates which are formed by joining repeated units of either monosaccharide or disaccharide .These units are bonded together by glycosidic bond. Example: cellulose and starch. Food sources containing polysaccharides are potatoes, oats

FOOD PRINT: The environmental impact, or foot print of food, including the amount of land required to sustain adiet, the amount of carbondi oxide produced, if the food is organic, and if it is local.

The monomer units of protein are amino acids

The monomer units of DNA are nucleotides

The monomer units of polysaccharides are sugars ( that is monosaccharides)
