Triglycerides are organic molecules that contain three different types of elements: carbon, hydrogen, and oxygen. But technically, lipids are a class of molecules that includes triglycerides, phospholipids, steroids, and waxes. So if you wanted to know what elements are found in lipids as a class, you'd have to allow for phosphorus as well, since phospholipids contain phosphorus in addition to carbon, hydrogen, and oxygen.
About Pinkeye. Conjunctivitis, commonly called pinkeye, is an inflammation of the conjunctiva, the clear membrane that covers the white part of the eye and the inner surface of the eyelids. Pinkeye can be alarming because it may make the eyes extremely red and can spread quickly.
Pinkeye is a nonmedical term which is commonly used by patients to describe conjunctivitis, an inflammation of the conjunctiva (the transparent covering of the white of the eye and inside of the eyelids). I consider pinkeye as synonymous with viral conjunctivitis, an infection caused by a variety of viruses in the eye. Most of these viruses reside in the respiratory tract and are spread through the air or by hand to eye contact.
