You Are What You Eat - RJBio1ntbk. The double bond causes a bend or a "kink" that prevents the fatty acids from packing tightly, keeping them liquid at room temperature. A class of macromolecules that are nonpolar and insoluble in water. Omega-3 fatty acids are important in brain function and normal growth and development. The structure of a macromolecule is a single molecule that consists of many covalently linked subunit molecules, and a polymer is a single molecule composed of many similar monomers. Any change in the gene sequence may lead to a different amino acid being added to the polypeptide chain, causing a change in protein structure and function. The elements carbon, hydrogen, oxygen, and nitrogen are the most common in plants.
What atoms are found in each of the following macromolecules? Monosaccharide: Gets its name from 'Mono' meaning 'one' and 'sacchar, ' meaning 'sugar. ' For example, hemoglobin is a globular protein, but collagen, found in our skin, is a fibrous protein. The number of carbons in the fatty acid may range from 4 to 36; most common are those containing 12–18 carbons. Enzymes, which are produced by living cells, are catalysts in biochemical reactions (like digestion) and are usually proteins. Amino acids consist of the following elements: carbon, hydrogen, oxygen, nitrogen, and, sometimes, sulfur and selenium. For example, hemoglobin is a combination of four polypeptide subunits. Carbohydrates are classified into three subtypes: monosaccharides, disaccharides, and polysaccharides.

Humans have thousands of proteins, each unique or specific in function and structure. 8 metres (6 feet), whereas the cell nucleus is about 6 μm (6 10-6 metre) in diameter—has a highly flexible helical structure that allows the molecule to become tightly coiled and looped. A single unit or monomer of carbohydrates. For example, they help keep aquatic birds and mammals dry because of their water-repelling nature. The carbon atoms may bond with atoms of other elements, such as nitrogen, oxygen, and phosphorus ( Figure 2b). Biological macromolecules are organic, as they contain carbon.
