Protein metabolism - Wikipedia
Protein metabolism denotes the various biochemical processes responsible for the synthesis of proteins and amino acids (anabolism), and the breakdown of proteins by catabolism. The steps of protein synthesis include transcription, translation, and post translational modifications.
24.4 Protein Metabolism – Anatomy & Physiology
Digestion of proteins begins in the stomach, where HCl and pepsin begin the process of breaking down proteins into their constituent amino acids. As the chyme enters the small intestine, it mixes with bicarbonate and digestive enzymes.

24.4 Protein Metabolism - Anatomy and Physiology 2e - OpenStax
The digestion of proteins begins in the stomach. When protein-rich foods enter the stomach, they are greeted by a mixture of the enzyme pepsin and hydrochloric acid (HCl; 0.5 percent). The latter produces an environmental pH of 1.5–3.5 that denatures proteins within food.
6.4: Protein Metabolism - Medicine LibreTexts
There are four protein metabolic pathways that will be covered in this section. The first step in catabolizing, or breaking down, an amino acid is the removal of its amine group (- NH3 NH 3). Amine groups can be transferred or removed through transamination or deamination, respectively.

2022年9月12日 · Metabolism refers to the whole sum of reactions that occur throughout the body within each cell and that provide the body with energy. This energy gets used for vital processes and the synthesis of new organic material.
Proteolytic enzymes responsible for degrading proteins are produced by three different organs: the stomach, the pancreas, and the small intestine. The digestion of proteins begins in the stomach, which secretes gastric juice—a unique solution containing hydrochloric acid and the proenzyme, pepsinogen.

2019年1月17日 · Metabolism of proteins, as annotated here, covers the full life cycle of a protein from its synthesis to its posttranslational modification and degradation, at various levels of specificity. Protein synthesis is accomplished through the process of Translation of an mRNA sequence into a polypeptide chain.
PROTEIN METABOLISM - Brigham Young University–Idaho
Proteins are responsible for most of the structure and function in our body tissues, so we probably don't want to metabolize them too extensively. In fact, the body employs several regulatory mechanisms to spare body proteins from metabolism.
Protein Metabolism - an overview | ScienceDirect Topics
Protein metabolism occurs in liver, specifically, the deamination of amino acids, urea formation for removal of ammonia, plasma protein synthesis, and in the interconversions between amino acids. Ingested protein is the sole source of the ten essential amino acids, and the primary source of nitrogen necessary for the synthesis of other amino acids.

10.5: Connections of Carbohydrate, Protein, and Lipid Metabolic Pathways
2021年4月27日 · Proteins are hydrolyzed by a variety of enzymes in cells. Most of the time, the amino acids are recycled into the synthesis of new proteins. If there are excess amino acids, however, or if the body is in a state of starvation, some amino acids will be shunted into the pathways of glucose catabolism (Figure 10.5.1 10.5. 1).
6.4 Protein Metabolism | Nutrition Flexbook - Lumen Learning
There are four protein metabolic pathways that will be covered in this section: Transamination: transfer of an amino group from one amino acid to another. Deamination: removal of an amino group, normally from an amino acid. Gluconeogenesis: synthesis of glucose from a non-carbohydrate source.

Human protein metabolism: its measurement and regulation
2002年12月1日 · in humans, the body protein mass provides architectural support, enzymes to catalyze metabolic reactions, signaling intermediates within and between cells, and fuel to allow survival. Because there is no protein storage pool, proteins that serve vital roles are catabolized when the body is faced with a need for additional fuel expenditure.
