WebThere are two important parts of a phospholipid: the head and the two tails. The head is a phosphate molecule that is attracted to water (hydrophilic).The two tails are made up of fatty acids (chains of carbon atoms) that aren’t compatible with, or repel, water (hydrophobic).The cell membrane is exposed to water mixed with electrolytes and other … WebProteins come in many different shapes and sizes. Some are globular (roughly spherical) in shape, whereas others form long, thin fibers. For example, the hemoglobin protein that carries oxygen in the blood is a globular protein, while …
