Struktur dan Fungsi Protein | Biomolekul #4

In this video, we explore the structure and types of proteins, starting with amino acids, the building blocks of proteins. Amino acids are simple molecules with a central carbon atom bonded to an amino group, a carboxyl group, and a variable side chain. There are hundreds of amino acids, but only 20 are proteinogenic, meaning they can combine to form proteins. These amino acids have different properties based on their side chains, which can be hydrophobic, hydrophilic, acidic, or basic. Proteins are formed by linking amino acids through peptide bonds, resulting in polypeptide chains that fold into three-dimensional structures. The folding is influenced by the environment, and changes can lead to denaturation, where proteins lose their function. The video also discusses the levels of protein structure: primary, secondary, tertiary, and quaternary, highlighting the differences between globular and fibrous proteins. Globular proteins are complex and diverse, while fibrous proteins are simpler and provide structural support.
