DD1: Proteins: Software Components of Life
DD 1: Proteins: Software Components of Life 1.1 Introduction to Proteins Proteins are the workhorses of the cell, performing a diverse array of functions. They are essential for life, playing roles in everything from structural support to enzymatic catalysis. 1.2 Types of Proteins Fibrous Proteins: Collagen: The most abundant protein in the human body, provides structural support to skin, bones, and connective tissues. Keratin: Found in hair, nails, and skin, provides protection and structural integrity. Elastin: Provides elasticity to tissues like skin and blood vessels. Globular Proteins: Enzymes: Catalyze biochemical reactions, such as the digestive enzymes amylase and pepsin. Hormones: Regulate physiological processes, such as insulin and growth hormone. Antibodies: Protect the body from pathogens. Hemoglobin: Transports oxygen in the blood. Membrane Proteins: Transport Proteins: Facilitate the movement of molecules across cell membranes, such as t...
