The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
Peptide Bond. Covalent bond between the nitrogen of the amino group of one amino acid and the carbon of the carboxyl group of a second amino acid, joining the 2 amino acids together in a peptide or protein.
When small organic molecules bind together, they form larger molecules called biological macromolecules. Biological macromolecules fall into four categories: carbohydrates, proteins, lipids and nucleic acids.Your body uses carbohydrates, lipids and proteins for energy. The only biological macromolecule not used for energy is nucleic acid. Nucleic acids hold and transcribe your genetic code.mall organic molecules called amino acids bind together to form the biological macromolecule protein. Protein is the building block of hair, blood cells, muscles and enzymes. If you consume more protein than your body needs, it converts into fat.
