What is the structural formula of fats?

What is the structural formula of fats?

Simple triglycerides are those in which each molecule of glycerol is combined with three molecules of one acid—e.g., tripalmitin, C3H5(OCOC15H31)3, the glyceryl ester of palmitic acid, C15H31COOH….Chemical composition of fats.

What is the structure of unsaturated fat?

unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond(s) and are therefore not completely saturated with hydrogen atoms.

What is a structural characteristic of a saturated fat?

Saturated fats have no double bonds in their chemical structure. They are saturated with hydrogen atoms. Because of their chemical structure, they have a solid consistency at room temperature.

What is the structure of saturated and unsaturated fatty acids?

Fatty AcidsSaturated fatty acids have hydrocarbon chains connected by single bonds only. Unsaturated fatty acids have one or more double bonds. Each double bond may be in a cis or trans configuration. In the cis configuration, both hydrogens are on the same side of the hydrocarbon chain.

What is the structure of fatty acids?

Generally, a fatty acid consists of a straight chain of an even number of carbon atoms, with hydrogen atoms along the length of the chain and at one end of the chain and a carboxyl group (―COOH) at the other end. It is that carboxyl group that makes it an acid (carboxylic acid).

Is saturated fat an element or compound?

saturated fat, a fatty acid in which the hydrocarbon molecules have a hydrogen atom on every carbon and thus are fully hydrogenated. (By way of comparison, the hydrocarbon molecules of unsaturated fats have two carbons that share double or triple bonds and are therefore not completely saturated with hydrogen atoms.)

Which molecule is a saturated fat?

saturated fat A fat molecule made from chains of carbon atoms, where each carbon has at least two hydrogen atoms attached to it (those on the ends have three). These chains have no double bonds. Saturated fats are found in animal fats (such as butter and lard), as well as in vegetable fats (such as coconut oil).

What are saturated fats biochemistry?

How is the chemical structure of saturated fats different from that of unsaturated fats?

In saturated fats, each carbon has four hydrogens bonded to it. Unsaturated fats have a carbon which has a double bond with another carbon. This double bond gives the molecule a bent structure, so they cannot stack on top of each other and are liquid at room temperature. These are the healthier fats.

How do you calculate saturated fat from fat?

Multiply the grams of saturated fat by 9 = (xx) the number of saturated fat calories in the food item. b. Divide (xx) the number of saturated fat calories in the food item by the total number of calories in the food item = % of saturated fat. 1) Fat – 3 x 9 = 27 fat calories; 27/90 = 30% total fat.

What is the chemical structure of saturated fat?

Each of the separate atoms attaches to the others only in precise predetermined ways. The backbone of a fat is a chain of carbon atoms (C). Hydrogen (H) and oxygen (O) atoms can then attach to the carbon. A saturated fat is a fat molecule in which all of the available binding sites are occupied by another atom.

What is saturated fat and what does it do?

Saturated fats are normally solid at room temperature. Most come from animal sources such as beef, poultry, whole-fat milk, cheese and butter, however several come from plant sources, like coconut, palm and palm kernel oils. Saturated fats raise levels of both total blood cholesterol and low-density lipoprotein, or “bad” cholesterol.

How much saturated fat to eat in a day?

Americans should consume less than six percent of their calories from saturated fats, according to the American Heart Association. This means that if you consume a 2,000-calorie diet, no more than 120 calories should come from saturated fats — roughly 13 grams a day.

What is the chemical formula for saturated fats?

Palmitic acid, or hexadecanoic acid in IUPAC nomenclature , is the most common saturated fatty acid found in animals, plants and microorganisms. Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0. As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil).
