Document Summary
The abundant elements in cells are: hydrogen, carbon, oxygen, nitrogen, phosphorus and su. Life is carbon based, with the other elements filling in to male different kinds of macromole. Carbohydrates energy storage, receptor, food, structural role in plants, fungal cell walls of insects. Lipids energy storage, membrane structure, insulation, hormones, pigments. Nucleic acids storage and transfer of genetic information. Proteins enzymes, structure, receptors, transport, structural role in the cytoskele and the extracellular matrix. Primarily composed of: carbon and water- empirical formula (ch2o)n. Monosaccharides simple sugars- building blocks of complex carbohydrates. Disaccharides made up of 2 monosaccharides covalently bonded - glyosidic bond. Ex: maltose, lactose, sucrose d sulfur olecules. alls, exoskeletons ts keleton of a cell. Polysaccharides aka, glycans- large polymers of monosaccharides (hundreds) Fatty acids lipids that contain long chain hydrocarbons with a carboxylic acid functional gr. Saturated: only single bonds - most amount of hydrocarbons possible. Unsaturated: contains double or triple bonds - fewer hydrogen atoms.
