Pigments are substances used to impart color to other materials. Unlike dyes, which chemically bond to the material they color, pigments retain their color because they reflect only specific wavelengths of light, absorbing all others. They work by scattering and absorbing certain light frequencies, with the unabsorbed light giving the pigment its color. Pigments can be derived from various sources, including minerals, plants, and synthetic processes, and are mixed with a binder to adhere to surfaces. Their stability, opacity, and non-solubility in the mixing medium make them versatile for applications in art, cosmetics, and industrial coatings. Pigments play a crucial role in the aesthetic and functional aspects of various products by providing color that is durable and stable under many conditions.
Amino acids, the building blocks of proteins, are synthesized by living organisms in two primary ways: from scratch (de novo) and by modification of existing amino acids. Essential amino acids, which humans cannot synthesize, must be obtained from the diet. In contrast, non-essential amino acids are produced within the body. The de novo synthesis involves complex metabolic pathways, where precursor molecules are gradually converted into amino acids through a series of enzymatic reactions. This process occurs in the cells of plants, animals, and microbes. Furthermore, certain amino acids can also be modified after they're initially synthesized to create variations needed for specific functions, a process known as post-translational modification in proteins.
Performing a yarn over (YO) after a purl stitch is straightforward but slightly different from doing it after a knit stitch. Here’s how: After completing your purl stitch, ensure your yarn is in front (as it naturally would be after purling). Then, instead of moving the yarn to the back over the needle as you would for a knit stitch, you simply bring it over the right-hand needle to the back and then proceed with your next stitch, be it a knit or a purl. This action creates the yarn over increase. If your next stitch is a knit, this step automatically positions your yarn correctly. However, if your next stitch is another purl, you'll need to bring the yarn back to the front under the needle to continue purling, which will also correctly form the yarn over. Practicing this maneuver will help make the yarn over seamless and contribute to the desired increase and decorative hole in your knitting project.
