Disaccharide A double sugar, consisting of two monosaccharides joined by dehydration synthesis. Glycosidic Linkage A covalent bond formed between two monosaccharides by a dehydration reaction. Phospholipid A lipid made up of glycerol joined to two fatty acids and a phosphate group. The hydrocarbon chains of the fatty acids act as nonpolar, hydrophobic tails, while the rest of the molecule acts as a polar, hydrophilic head. Phospholipids form bilayers that function as biological membranes....

Phospholipid Made up of a glycerol backbone (3 carbons), hydro-carbon tail, and phosphate (negative) choline (positive) head group Have two hydrophobic hydrocarbon (oily) tails Hydrophilic phosphate head How the phospholipid layers form? The hydrophobic fatty acid tails and hydrophilic polar heads are part of the lipid bilayer. The tails repel water, so they are always facing the inside of the membrane. The polar heads love it, so they face the outside of the membrane. tails -> away from w...
