Which of these groups of compounds are phospholipids? Group of answer choicessphingomyelinsleukotrienesfatty acidsadrenal cortical steroids

The group of compounds that are phospholipids among the options provided is sphingomyelins. Phospholipids are a class of lipids that are a major component of all cell membranes as they can form lipid bilayers. Sphingomyelins are a type of phospholipid found in animal cell membranes, especially in the membranous myelin sheath that surrounds some nerve cell axons. They play an important role in signal transmission and cell recognition. Leukotrienes, fatty acids, and adrenal cortical steroids, on the other hand, are not classified as phospholipids.
