Question

By which type of bond lipid is formed?

Answer 1

Steroids are lipids since they are hydrophobic and insoluble in water, but their structure is different from lipids because it is made up of four fused rings. Vitamin D, testosterone, oestrogen, progesterone, aldosterone, cortisol, and bile salts are all precursors to cholesterol, which is the most prevalent steroid.

Complete answer:
A glycerol molecule with three OH groups can join with one fatty acid (to form a monoglyceride) and up to three fatty acids (to form a triglyceride) (form triglyceride).

A triglyceride is the fundamental unit of lipids. A triglyceride is generated when one glycerol molecule forms an ester bond (covalent bond) with three fatty acid molecules in a condensation reaction.

Saturated and unsaturated fats and oils can be unhealthy, but they also perform crucial purposes in plants and animals.
Many vitamins are fat soluble, and fats serve crucial functions. Fats are a source of energy as well as a long-term storage form of fatty acids. They also help to keep the body warm.

Fatty Acids and Glycerol
Glycerol and fatty acids are the two primary components of a fat molecule. Glycerol is a three-carbon alcohol with five hydrogens and three hydroxyl (OH) groups. Fatty acids are made up of a long chain of hydrocarbons with a carboxyl group attached. They can have anywhere from 4 to 36 carbons, but the majority have 12 to 18. Fatty acids are connected to each of the three carbons of the glycerol molecule via an ester bond through the oxygen atom in a fat molecule. Three molecules are released during the ester bond formation. Triacylglycerols or triglycerides are lipids that are made up of three fatty acids and a glycerol.

Fatty Acids: Saturated vs. Unsaturated
Saturated and unsaturated fatty acids exist. A fatty acid chain is said to be saturated if there are only single bonds between surrounding carbons in the hydrocarbon chain. Because single bonds increase the number of hydrogens on each carbon, saturated fatty acids are hydrogen-rich. Saturated fats include stearic acid and palmitic acid, which are typically present in meat.

The fatty acid is said to be unsaturated when the hydrocarbon chain contains a double bond. Unsaturated fatty acids, such as oleic acid, are a type of fat. Oils are mostly unsaturated fats that are liquid at normal temperature. Monounsaturated fats are those with only one double bond in the molecule, such as olive oil. A polyunsaturated fat is one that has more than one double bond, such as canola oil. Saturated fats promote plaque formation in the arteries, whereas unsaturated fats assist reduce blood cholesterol levels.
Unsaturated fats and oils are made up of cis unsaturated fatty acids and are mainly derived from plants. The molecule's orientation around the double bond is indicated by the letters cis and trans. A cis fat is one in which the hydrogen atoms are in the same plane; a trans fat is one in which the hydrogen atoms are on two distinct planes. The cis double bond creates a kink in the fatty acids, preventing them from packing tightly and keeping them liquid at room temperature.

Note:-
Trans Fats are a type of fat that can be found. Oils are artificially hydrogenated in the food business to make them semi-solid and of a consistency suitable for many processed foods. Gas is bubbled through oils to harden them during this hydrogenation process, and the cis-conformation double bonds in the hydrocarbon chain may be changed to double bonds in the trans-conformation.
