Study Notes
Macromolecules Overview
- Amino acids serve as the building blocks of proteins, containing nitrogen (N) in addition to carbon (C), hydrogen (H), and oxygen (O).
- Carbohydrates act as the primary fuel source for body cells and are composed of elements C, H, and O in the ratio of CHâ‚‚O.
- Lipids (fats) are not water-soluble and contain C, H, and O but with lower oxygen content. They insulate the body and are found in cell membranes, with cholesterol being a typical member of this class.
- Nucleotides are the building blocks of nucleic acids, containing nitrogen, phosphate (P), C, H, and O.
Carbohydrates
- Major energy source for cells, significantly present in foods like bread and sugary treats.
- Monosaccharides represent the basic building blocks of carbohydrates, with their chemical ratio being CHâ‚‚O.
- Starch serves as a storage carbohydrate for plants, while glycogen plays the same role for animals.
- Disaccharides such as lactose and maltose are composed of two monosaccharides.
Proteins
- Predominant component of cellular cytoplasm, essential for various functions.
- Found in high amounts in meat and cheese, proteins include fibrous types like collagen and keratin, and functional types like enzymes, hemoglobin, and hormones.
- Proteins are made from amino acids, which vary by their unique R groups.
Lipids and Fatty Acids
- Lipids include fats and cholesterol, with fatty acids serving as their building blocks alongside glycerol.
- Major dietary sources of lipids include egg yolks and peanut oil, highlighting their importance in nutrition.
Nucleic Acids
- DNA and RNA contain the genetic information essential for heredity and protein synthesis.
Other Important Terms
- Hydrolysis refers to the chemical process that breaks down polymers into monomers during digestion.
- The term "R group" differentiates individual amino acids within proteins, indicating their unique properties.
