π Food is a source of biomolecules, including carbohydrates, lipids, proteins, and nucleic acids.
𧩠Different types of food contain varying amounts of these biomolecules.
ποΈ Understanding biomolecules is important for understanding the structure and function of cells and organisms.
π‘ Carbohydrates are found in food sources like bread, pasta, fruit, and vegetables.
βοΈ The monomer of a carbohydrate is a monosaccharide, such as glucose.
π Monosaccharides can combine to form disaccharides like maltose.
π Carbohydrates are a major energy source for cells and can be stored as polysaccharides.
π Lipids, including fats and oils, are diverse and generally hydrophobic.
π Phospholipids play a key role in cell membranes.
π‘ Lipids serve as a source of long-term energy storage and provide insulation for cells.
π¬ Lipids also act as hormones and play a role in various processes within the body.
π Proteins, made up of amino acids, are crucial for the structure and function of cells.
𧬠Proteins are essential biomolecules found in various forms, including collagen, cell membranes, receptors, and enzymes.
π©Ί Antibodies, made by immune cells, and hormones such as insulin are important proteins involved in protecting and regulating the body.
π Genes, which are made of DNA, code for proteins, and nucleic acids like DNA and RNA serve as the building blocks of genetic information.
π When you eat something from a living organism, like a strawberry, it can still contain DNA.
𧬠Nucleic acids, such as DNA and RNA, are important for the genetic information and coding of traits in our cells.
π’ Carbohydrates, lipids, proteins, and nucleic acids are the four main biomolecules, and a popular mnemonic to remember their common elements is CHO, CHO, CHON, CHONP.
π The arrangement of elements in biomolecules greatly impacts their function.
