GENERAL KNOWLEDGE

Detailed explanation-1: -Steroids are another class of lipid molecules, identifiable by their structure of four fused rings. Although they do not resemble the other lipids structurally, steroids are included in lipid category because they are also hydrophobic and insoluble in water.

Detailed explanation-2: -Steroids are fat-soluble and nonpolar molecules that are found in every biological system. It has a fused ring structure and is a precursor to various biomolecules such as cholesterol, testosterone, progesterone, etc. Steroids are not considered true lipids.

Detailed explanation-3: -(STAYR-oyd) Any of a group of lipids (fats) that have a certain chemical structure. Steroids occur naturally in plants and animals or they may be made in the laboratory. Examples of steroids include sex hormones, cholesterol, bile acids, and some drugs.

Detailed explanation-4: -Steroids are a type of lipids with a distinct chemical structure. While they are dissimilar to other lipids in structure, scientists classify them as lipids because they are hydrophobic-meaning they repel water-and insoluble in water. All steroids have four linked carbon rings.

Detailed explanation-5: -Lipids include fats, oils, waxes, phospholipids, and steroids.
