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: -3. Steroids. Although they do not often contain fatty acids the steroids are frequently classed as lipids on account of their occurrence in natural fats and their solubility characteristics. They include cholesterol and the sex and adrenocortical hormones.

Detailed explanation-3: -Steroids can interact with fatty acids as they have a-OH group attached to the ring. Cholesterol is the most common example of a steroid molecule.

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: -One major class of lipids is the steroids, which have structures totally different from the other classes of lipids. The main feature of steroids is the ring system of three cyclohexanes and one cyclopentane in a fused ring system as shown below. There are a variety of functional groups that may be attached.
