what can you tell me about the fourth biochemical mentioned above?
Often called fats, they are hydrophobic biological molecules but will dissolve in organic solvents such as alcohol, benzene.
Metabolism
Lipids are the most diverse group of biochemicals. Their main structural uses are as part of biological membranes both internal and external, such as the cell membrane, or as a source of energy. Lipids are usually defined as hydrophobic or amphipathic biological molecules but will dissolve in organic solvents such as alcohol, benzene or chloroform. The fats are a large group of compounds that contain fatty acids and glycerol; a glycerol molecule attached to three fatty acid esters is called a triacylglyceride. Several variations on this basic structure exist, including backbones such as sphingosine in the sphingomyelin, and hydrophilic groups such as phosphate as in phospholipids. Steroids such as sterol are another major class of lipids.
what is metabolism? The set of life-sustaining chemical reactions in organisms. what are the key biochemicals? Amino acids, carbohydrates, nucleic acid and lipids how is the name of the second one formed? Carbon + hydrogen + oxygen (usually with a hydrogen–oxygen atom ratio of 2:1 as in water) can you tell me about its structure? A typical monosaccharide has the structure H–(CHOH)(C=O)–(CHOH)–H how is the aforementioned structure cyclised? The open-chain form of a monosaccharide often coexists with a closed ring form where the aldehyde/ketone carbonyl group carbon (C=O) and hydroxyl group (–OH) react forming a hemiacetal with a new C–O–C bridge.
