What is the structure of corn oil?
Refined corn oil is composed of 99% triacylglycerols with polyunsaturated fatty acid (PUFA) 59%, monounsaturated fatty acid 24%, and saturated fatty acid (SFA) 13%. The PUFA is linoleic acid (C18:2n-6) primarily, with a small amount of linolenic acid (C18:3n-3) giving a n-6/n-3 ratio of 83.
What is the chemical structure of cooking oil?
INTRODUCTION: Vegetable oils are composed of triglycerides. The triglycerides are molecules that contain carbon, hydrogen and oxygen, and its structure includes glycerol and three fatty acids. The fatty acids present in triglycerides may be the same or of different types.
What is the molecular structure of oil?
Fats and oils are composed of molecules known as triglycerides, which are esters composed of three fatty acid units linked to glycerol. An increase in the percentage of shorter-chain fatty acids and/or unsaturated fatty acids lowers the melting point of a fat or oil.
What is the chemical structure of olive oil?
Olive oil is composed mainly of triacylglycerols (triglycerides or fats) and contains small quantities of free fatty acids (FFA), glycerol, phosphatides, pigments, flavor compounds, sterols, and microscopic bits of olive. Triacylglycerols are the major energy reserve for plants and animals.
What is the advantage of corn oil?
Corn oil is high in anti-inflammatory phytosterols and other compounds that may help reduce certain heart disease risk factors, such as LDL (bad) cholesterol and total cholesterol.
What are the physical properties of corn oil?
3. Results and discussion

What is the physical properties of cooking oil?
Physical properties include viscosity, density, cloud point, pour point, flash point, boiling range, freezing point and refractive index. There exist a number of correlations for estimating the HHV of vegetable oils based upon its physical properties [11], [12], [31].
What is milk chemical formula?
Water is the most availble resource on Earth’s surface, it covers 70 percent of the Earth. Water can exists in a liquid, solid, and gaseous state. lactoses molecular formula for lactose is C12H22O11. Lactose is formed from galactose and glucose units. Lactose is the main carbohydrate in milk.
What is milk made up of chemically?
The principal constituents of milk are water, fat, proteins, lactose (milk sugar) and minerals (salts). Milk also contains trace amounts of other substances such as pigments, enzymes, vitamins, phospholipids (substances with fatlike properties), and gases.
What is the chemical composition of corn oil?
Corn oil consists largely of a mixture of triglycerides. Since it is not a pure compound, it does not have a single chemical formula.
What chemical compounds are contained in corn?
– Ferulic acid. – Anthocyanins. This family of antioxidant pigments is responsible for the color of blue, purple, and red corn ( 23, 24 ). – Zeaxanthin. Named after corn’s scientific name ( Zea mays ), zeaxanthin is one of the most common plant carotenoids. – Phytic acid. Corn provides higher amounts of antioxidants than many other cereal grains.
What is the chemical structure of vegetable oil?
The molecular structure of vegetable oil consists of glycerol and fatty acids. Glycerol has 3 carbon atoms and fatty acids are long chain of carbon atoms. Vegetable oil is nonpolar as it can also be dissolved in nonpolar compounds such as gasoline.
What is the composition of corn?
Like all cereal grains, corn is primarily composed of carbs. Starch is its main carb, comprising 28–80% of its dry weight. Corn also provides small amounts of sugar (1–3%) (1, 2). Sweet corn, or sugar corn, is a special, low-starch variety with higher sugar content, at 18% of the dry weight.
