What is PROTEIN? PROTEIN meaning – PROTEIN definition – How to pronounce PROTEIN

Protein makes up your nails, your hair and the egg on your plate. This nitrogenous substance. We call protein, consists of chains of amino acids and is necessary for life functions. Most microorganisms and plants can bio, synthesize all 20 standard amino acids, while animals, including humans, must obtain some of the amino acids from the diet. 23. The amino acids that an organism cannot synthesize on its own are referred to as essential amino acids. Key enzymes that synthesize certain amino acids are not present in animals such as esparto kinase, which catalyzes the first step in the synthesis of lysine, methionine E and threonine II from aspartate. If amino acids are present in the environment, microorganisms can conserve energy by taking up the amino acids from their surroundings and down regulating their biosynthetic pathways. Although protein is a word often heard in labs and biology classes, it is everyday context to particularly in the kitchen protein rich foods like eggs, cheese, meats, peanuts or beans are an essential part of good nutrition in animals. Amino acids are obtained through the consumption of foods containing protein ingested. Proteins are then broken down into amino acids through digestion, which typically involves nature. Ation of the protein through exposure to acid and hydrolysis by enzymes called proteases some ingested amino acids are used for protein biosynthesis, while others are converted to glucose through gluconeogenesis or fed into the citric acid cycle. This use of protein as a fuel is particularly important under starvation conditions, as it allows the body’s own proteins to be used to support, particularly those found in muscle. The linguistic origins of protein from the Greek Proteus, meaning first place or primary, are fitting for a substance that is one of life’s chief components.
