Lipid
Some dietary fat is necessary to facilitate absorption of fat-soluble vitamins (A, D, E, and K) and carotenoids. Humans and other mammals have a dietary requirement for certain essential fatty acids, such as linoleic acid (an omega-6 fatty acid) and alpha-linolenic acid (an omega-3 fatty acid) because they cannot be synthesized from simple precursors in the diet. Both of these fatty acids are 18-carbon polyunsaturated fatty acids differing in the number and position of the double bonds. Most vegetable oils are rich in linoleic acid (safflower, sunflower, and corn oils). Alpha-linolenic acid is found in the green leaves of plants, and in selected seeds, nuts, and legumes (in particular flax, rapeseed, walnut, and soy). Fish oils are particularly rich in the longer-chain omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Many studies have shown positive health benefits associated with consumption of omega-3 fatty acids on infant development, cancer, cardiovas
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. 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.

Lipid [SEP] Nutrition and health
Most of the fat found in food is in the form of triglycerides, cholesterol, and phospholipids. Some dietary fat is necessary to facilitate absorption of fat-soluble vitamins (A, D, E, and K) and carotenoids.
